this is al jazeera america. here is a look at today's top stories. the fragile cease pyre in syria-- fire in syria. it's in its second day and already there are reports of violations. >> i don't know anything about what you're even talking about with white supreme cy donald trump damage control after he claimed he didn't know enough about the kkk to disavow

them >> he said he doesn't know who david duke is his competition wasting little time making it a campaign issue. lost in the headlines, hillary clinton beats bernie sanders is south carolina and looks ahead for a make or break super tuesday. a landmark abortion case to be heard this week. it could affect the ability of women's health clinics to treat patients. that's the top of tonight's the week ahead. -- topic of we begin with the ceasefire in syria. it is now day two and there are claims the agreement is already being violated. a top official with the syrian opposition says russian iranian and government forces have not stopped hostilities. according to that official

russian war planes carried out 26 air strikes today targeting rebels that are abiding by the truce. >> reporter: day two of the truce in syria got off to a bad start. a war plane believed to be russian hit a number of villages and towns in the countryside of aleppo province. people here in the town thought they were safe. many people woke up to this following the early morning raids. >> translation: people were sleeping. what truce. they hit the houses, the shop, the markets. get your militias out. those from iran and hezbollah. >> reporter: the truce is meant to spare these people but it seems it didn't. the rebel group, al-nusra, with links to al-qaeda, is excluded from the ceasefire deal along with i.s.i.l. people understand that al-nusra fighters here but people say the group is a number of rebel groups controlling in area.

the terms of the truce can be interpreted differently by all the warring sides. the ministry of defense in moscow says russian strikes are not a violation of the terms of truce because al-nusra was the target. the russians say they recorded nine violations on the rebel side in the last 24 hours. fighting is also being reported between government forces and the rebels in the latakia province appeared in other areas. turkey's president is also warning kurdish fighters the y.p.g., who are fighting i.s.i.l. in northern syria, that the turkish army will stop them from creating a free corridor on turkey's southern border and that could worsen the fragile truce russian authorities believe 36 people have died at a mine where rescuers were trying to

free trapped miners. >> reporter: rescue efforts have been called off now. the series of methane explosions mean that it's just too unsafe to try and see if anyone else is still alive. the mining company is trying to work out what to do next. it has two options, really. flood the mine with water to try and put out the fires that are still burning or shut off the air supply and asphyxiate the flames. the emergency ministry here says the conditions are so severe down this mine that they don't think there are any survivors left. russia does have a pretty lamentable record for mining. there are safety regulations on paper but often these are not properly enforced. the also the fact that these

mines are often in very remote parts of the country mean that when things do go wrong, it's very difficult to actually mount a proper rescue operation to the race for the white house now. republican candidate donald trump's damage control over comments about support he is getting from the kkk. the g.o.p. front runner ignited a media onslaugt when he didn't immediately separate himself from the kkk organization. he said he needed more research. more from al jazeera's correspondent. >> reporter: the controversy started on wednesday when the white supremecist david duke urged listeners of his radio show to support donald trump for precedent. >> running against donald trump at this point is really treason to your heritage. >> reporter: at a press conference friday, he responded. >> i didn't even know he endorsed me. david duke endorsed me.

all right. i disavow. >> reporter: the matter didn't die there. he was called on to go further and confirm the racism. he was repeatedly pressed. >> even if you don't know about their endorsement, there are these groups and individuals endorsing you. would you say you condemn athem and you don't want their support? >> well, i have to look at the group. i don't know what group you're talking about. >> reporter: i'm talking about david duke and the kkk here >> honestly, i don't know david duke. i don't believe i've ever met him. i just don't know anything about him >> reporter: as criticism mounted, donald trump tweeted repeated his disavowal but his opponents saw an opening >> should the erred head of the conservative movement be someone who refused to criticise the

kkk. >> reporter: later sunday john kasich also weighed in: by late afternoon when donald trump addressed a large rally in alabama and notched his first endorsement, he had managed to define and dominate the day's political news condemnation of donald trump's comments is something that both democrats bleed on. bernie sanders says america's first black president cannot be succeeded by a hate group. chris christie condemned his endorsement of donald trump. meg whitman released a statement:

chris christie reacted to comments. >> i love meg. she is a great friend to me. always has been. we obviously have a difference of political opinion. that's okay. that's what makes this country great so people can have differences of political opinion. meg has always been free to express her views and i honor her. we absolutely adore our relationship with her and i'm sure it will continue he also denied telling a report that he would not endorse donald trump. to the democratic campaign now. hillary clinton appears to be focusing her attacks on donald trump instead of bernie sanders. this shift comes fresh off her huge win in south carolina where she easily beat sanders. she did the with 85% of the black vote, a group that could be the deciding factor in november. a senior white house correspondent has more. >> reporter: the focus now turns to super tuesday and contests like the caucuses.

after hillary clinton beat bernie sanders in south carolina, it could soon be effectively over. >> we just got here and it's just so beautiful. >> reporter: hillary clinton is on the verge of seizing control of the democratic race. after her resounding win in south carolina, she campaigned sunday in tennessee, one of 11 states with delegates up for grabs on super tuesday. she won by over 40%. hillary clinton didn't let up. >> tomorrow this campaign goes national. in the aftermath of the blow out lauls, sanders had few positives to spin. >> we got decimated. that's what happened. >> reporter: it wasn't just the 47 point margin, but it supposed the weakness. african-americans who backed clinton with 84% of their vote.

if bernie sanders loses blacks in a similar margin on tuesday, hillary clinton would rack up a big lead. putting bernie sanders back to where he started months ago, as a long shot to win the nomination. >> reporter: a chance to put sanders away, hillary clinton is calling for democrats to unite. turning to donald trump and anticipating a match up in the election. >> instead of building walls we need to be tearing down barriers. we need to show by everything we do that we really are in together. >> i give you bernie sanders. >> reporter: instead of south carolina, saturday night he rallied with supporters in minnesota a super tuesday state he thinks he can win. he repeated his call for social and economic justice and, again, challenged clinton to release transcripts of her speeches to gold man sach;

>> if you get $225,000 for a speech it must be a really excellent wonderful speech and therefore you should be very proud to release the transcript of that speech. >> reporter: in the crowd supporters knew of the route in shrine, but were not ready to give up. i'm discouraged maybe a little bit, but i'm an optimist, so obama too, people wrote him off and look at what he was able to do. >> reporter: bernie sanders says he is ready for a drawn-out fight for the nomination, but super tuesday and the contest in the next two or three weeks will decide whether the fight will be worth it hillary clinton may have won fans today. she campaigned with tony gold abouts win from the series scandal. he said he picks hillary clinton over bernie sanders because she gets things done. he called her tyreless in her

efforts. >> we all need to fight as hearted for hilary as reknow she will fight for us when she gets behind that desk in the oval office, the one that i pretend to sit behind in my day job >> i went over in l.a. and looked at the set. boy was it realistic. >> reporter: she says scandal's main actress will be appearing in commercials for her. things went off script when former president bill clinton held a rally on behalf of his wif wife. >> this is america. i get to answer back. i heard your speech. they heard your speech. you listen to me now. i'm not your commander in chief any more, but if i were i would

tell you to be more polite. sit down the heckler was removed from the event. he claims to be an iraqi war veteran. bernie sanders was interrupted atoday during his standard stump speech but to different effect. >> young people are saying - look. well, thank you. i love you too. what i was saying, we listen to young people, it wasn't necessarily that they all loved me, but i do appreciate that bernie sanders home state of vermont holds its primary on tuesday, so does hillary clinton former home state arkansaw. for whom ever wants to win the vote, the hispanic votes are keen.

the g.o.p. says maybe not leaning towards the democrats. a police officer killed on her fur first day on the job. later a landmark abortion rights case to be heard by the court this week. it could affect the ability of women's health condition to treat patients.

super tuesday states like texas and colorado include large blocks of hispanics.

because they attract democrat crack, republicans are working hard. >> do you know what i really am happy about because i've been saying it for a long time, 46% with the hispanics. >> reporter: less than 8% of the nearly 80,000 republicans who voted in the caucus are hispanic. >> how many of you are first time caucus goers. >> reporter: a record 27.3 million latino voters across the country are eligible to vote in this year's presidential election >> no candidate, neither democrat nor republican, can win without our vote, without the concerns that we have. they need to address those concerns. >> reporter: polls suggest latino mostly lean towards the democrats with hillary clinton

slightly favored overall. >> most likely to win the general election next november. >> as i understand it, we actually won the latino vote yesterday, which was a big break through for us >> that's not what our analysis shows. >> reporter: according to a new washington post survey, 81% of hispanics nationwide have an unfavorable view of donald trump. only 16% would vote for him over a democratic presidential candidate. if it holds up, a margin like that could decide the election >> we are the person of diversity not the democratic party judge the poll suggests that marco rubio and ted cruz will be better than donald trump. >> i'm going to tell you the most powerful sentiment in the hispanic community, is the

burning desire to leave your children better off than yourself. that's what we substantive for, not socialism. >> reporter: an analysis from the polling firm latino decisions suggests that the republican nominee will need to win at least 47% of the hispanic vote to become the next president early al jazeera spoke to brent wilks at the league of the latin american citizens. he expects a large turn out in the election >> i think you're going to see a huge latino turn out. if donald trump you will see a large turn out anyway because they're very engaged in this election, they've seen how damaging his words are and how his policies could hurt their families and to really deny opportunity, whether it be education or employment opportunities. because of that they are attuned to this election.

they're planning to participate. we've seen the enthusiasm, the momentum. you did a clip on some of our iowa campaign. toil tell you, we wasn't from one thousand latino voters in the iowa caucuses to over 13,000 in this. they're engaging like they never have before and they're going to be voting against donald trump and his policies. i think that is a big problem for republicans. they have to try to stop donald trump, which i think is the best play of action or they've got to figure out what they're going to do because they're really going to be in trouble if he is the standard bear for the party here is what is at stake on tuesday. voters in 12 states will go to the polls and you can see most of them in the south. for democrats 86 of 5 delegates are up for grab, for the republican 575 are available. al jazeera america will bring you full coverage tuesday night. a ban on international adoptions was imposed by the government

three rears ago nonsense so child abuse reports in the u.s. what was supposed to protect children has opened the way to a business in child trafficking. >> reporter: these are some of the destitute children here. they've been orphaned or abandoned here at the home at the edge of the city. she arrived a few days ago. she was found alone in the streets in one of the foundships. the 92 children here are waiting to be adopted, but the government suspended adoptions four years ago and it has been tough. >> translation: we have to keep children who have already been adopted and we are still receiving new arrivals. it is hard to take care of all of them and provide their basic needs. >> reporter: things may get better. 70 children who had already been adopted in countries like france, canada and the u.s. will now get exit visas that will

allow them to travel another 190 were issued with visas last year. after years of waiting they can join their adopted families from france. like other parts of the country, here you will find many abandoned children. the ban on international adoptions were meant to protect such vulnerable children, some of whom who end up being abused in foreign countries. since the ban, there have been more record cases of child smuggling. this woman says her four year old twins were taken from her village. she said she followed reports they had been taken to an orphanage in the capital but arrived too late. now all she has to go on is the picture of the american man who she was told have her children in the u.s. >> translation: i just want to tell whoever has my children to return them. i am not asking for anything else. i have nowhere to live in this city. i have been sleeping on the floor. i have been robbed.

but i won't go back home without my children. >> reporter: this man runs one of the company's international adoption agencies. he says a bill currently before parliament could see the lifting of the moratorium and proper regulation of foreign adoptions. >> translation: if passed, the law will have a provision for community to monitor the progress of the children when they leave the country. if properly implemented, child trafficking will be a thing of the past >> reporter: back at the home they may be too young to understand how a new improved law may help them, but those who take care of the children says they want to see them placed with stable loving families here or abroad in virginia an army staff sergeant is under arrest for the murder of a rookie police officer. authorities say ronald ham iltop killed his wife after a domestic dispute outside of washington. when police arrived, reports of

gun shots. he openeded fire killing the officer. it was her first day on the job after being sworn in. she had started the process of becoming an officer before but left during training and later returned. >> she felt like she still wanted to do this job. she couldn't get it out of her blood. it was something that he thought she could pour herself into, which is exactly why she re-applied and sought to be rehired. she clearly had a passion to serve others in a way that went beyond herself she had been an intern for the department and had a masters degree in france science. a ship is ending a voyage quickly. it was put back into service after battering incident three weeks ago. the ship is now set to drop anchor in new jersey on 1 march ending a 13-day voyage two days early. it seems as if no industry is

safe from hackers. that includes hospitals. while they have recommdations breaking into the health care industry can be profitable, it can also be deadly. such cyber attacks are a sign of the times. >> reporter: a hollywood hospital is the scene of a crime that once would have only been a thing of the movie. >> all the sign said do not use the computers. i'm going on what's going on here some in they said we got hacked >> reporter: hackers took control of the center's network, infecting its files with what is called ransom wear. >> it infects file after file after file. typically there is a key to undo it >> reporter: the absent ...-- anti antid antidote only after paying 17,000. hospital hacks do not just compromise your data.

they can cause your death. >> every gaming console that you can buy at the toy store, the wii, the playstation, x box, those have all gone cyber security reviews. the device in a hospital more than likely has not gone through any type of formal review at all. >> reporter: so you're telling me a playstation has more review than at morphine infusion pump? >> absolutely. >> reporter: this man is a society security expert, having identified threats and weaknesses for the u.s. military, google and microsoft. one of his specialists, hospital equipment. do you think hospital equipment is vulnerable or do you know hospital equipment is vulnerable >> we know it's vulnerable. we have data that shows that. >> reporter: on any given day he says there can be tens of thousands of devices connected to a network in a typical

hospital. everything-- typical hospital. everything from incubators to fusion pumps. any of which can be hacked and made lethal. >> that's not a thing that we think could happen. we know it could happen. we have demonstrated it for government agencies and the fda >> reporter: he says not only can the devices be hacked and turned against the very patients they're supposed to be helping, but when they access the equipment, they're also accessing all your personal data stored in it with far-reaching implications. so somebody could get in there and modify your data, change your blood type >> right, yes >> reporter: change a dosage level and the doshg tore wouldn't know the difference-- doctor isn't going to know about it >> that's right. they will make decisions about your care on that information. that is very dangerous

when the supreme court meets this week on its docket, a landmark abortion rights case. >> there was no way that i could continue the pregnancy knowing that there was no chance of survival for the baby it could affect the ability of women's health clinic to treat patients.

welcome back to al jazeera

america. republican presidential candidate donald trump is gathering endorsements from party members. donald trump is facing criticism from david duke. donald trump said he wasn't family with the group but on friday he said he disavowed the endorsement. the ceasefire in syria has ended with days of violations. hostilities have not been stopped. russian aeroplanes carried out 26 attacks today. in greece today more than 3,000 migrants arrived. 350 had to be rescued by patrols. greece's migration minister warns up to 70,000 migrants could be trapped in the country in the coming weeks

it is sunday night and time for our regular look at the week ahead. on wednesday, the supreme court will hear arguments in a landmark case for abortion rights. a women's health center in texas is challenging a law that requires clinics to meet standards. it requires doctors to have admitting privileges attend local hospitals and requires clinics to meet same standards to an emergency room. it will keep abortion clinics safe for women. critics say it will reduce access to care. half of the clinics in texas has been forced to close because they were unable to adhere to the new rules. it has been seen across the u.s. activists are concerned about women in texas and louisianna. similar attempts have been

blocked in area areas. a closer look at what is at stake. >> reporter: the texas says before the supreme court mau have the biggest impact on abortion law across the country sin . there are nine other states that have similar laws. question before the justices is whether they were in favor. one woman wanted her pregnancy but aftering her foetus had a fatal condition her nightmare just continued. >> i saw you at least temporarily yesterday via you will extra sound. it became real. you are growing in my bell ee >> reporter: she says she was thrilled. already the mother of two girls she had been excited at the

prospect of having a boy >> every time i would see the ultrasounds, you would wave at me >> reporter: then at 12 weeks a new you will extra sound revealed a grave problem. the foetus's brain had not fully developed. the doctor had terrible news >> he told me it was 100% incompatible with life >> reporter: she was left with a difficult decision, terminate or have a still born baby. she chose to have an abortion >> it was no way that i could continue the pregnancy knowing that there was no chance of survival for the baby. >> reporter: she wanted the abortion immediately but she was told she might have to wait weeks for an appointment. with more than half of text's' abortion clinics shut, she said she could not wait and went to florida the next day. >> i had moments where it was

hard, but you have to develop a coping mechanism to deal with the loss, but more so to still deal with the loss that i believe is just cruel for a woman that was in the situation i was put in. i think about women who may not have the resources that i had to be able to travel out of state to have the procedure done. >> reporter: indeed. women with fewer resources face a more difficult challenge and nowhere in texas is that challenge greater than here in the border region where more than a third of the mostly latino population live in poverty. access to health care here was already scarce, made worse when all but one abortion clinic closed. this clinic is the only one within 250 miles. >> there is waiting periods and there's multiple visits that

women need to make and so they have to get child care more than once, time off work, there's travel. for a lot of people that can be conflicted >> reporter: if not impossible. advocates for the restrictions say they're meant to make the procedures safer. one abortion clinic cannot serve a population of two million women along the border. some women are seeking another solution, a dangerous one in mexico. in a pharmacy just across the border we find the drug commonly used to induce medical abortion. it is available in mexico without a description. >> translation: it is made to treat stomach sul sers, but it-- ulcers, but it can only destroy the foetus and give the woman an abortion. >> reporter: he says he gets asked for the immediate inweekly

at $180 a box. he has seen a massive increase. the medication can be dangerous when taken without a doctor's prescription. >> we are hearing people trying to induce an abortion by physical abuse. >> reporter: women who is say no. >> of course we want women to be safe. we want anybody that has to have any type of medical care to be safe. the emotional impact of it is what i think the court should really take into consideration because that is very burdensome. it is a heavy burden that you can't really explain. it is a pain there.

>> reporter: so you've heard now from women from across the state of texas with very different backgrounds coming from very different circumstances all complaining that these laws do play an undue burden. however, when the justices hear this case on friday, it may be remain to be seen whether the question will be decided. with one justice seat say vacated in the four four time among the remaining justices, then the lower court's ruling would prevail but the greater constitutional question will ham unanswered thank you very much for joining us. joining me in the studio, the editor of human life review and film maker. this is the first time in decades that the supreme court is hearing a case like this that will have such an impact on abortion rights. how do you explain what is at

stake here, what are you expecting to happen this week? >> well, i think two major things are at stake. one is that an issue is that whether or not the states can regulate their own health clinics, so the texas laws which actually came as a result of the goznell case, the horrors that were revealed, where they found out that his clinic had not been snengtd or regulated at all and women and children died. it was just horrific-- inspected. the regulations at the supreme court is whether or not a state can regulate its own health clinics and whether these regulations, which are to be within 30 miles of a hospital, and to have the same quality asam bulaty surgical theatres,

whether they place a bar to the women. i say there would not. i think we productive rights include preserving reproductive rights in the future and making sure that they're healthy. what is at stake is if there is a five three decision, this could set a precedent for many her states you've made a documentary. you've spoken to several of these doctors who feel differently about what's going on here. before i ask you a question, i want to show a little clip of your documentary just so people can know what you've done >> in texas today the governor - they could soon with in the fight to fight abortion. women are going to have abortions. it's just that they are not going to be safe i just want to get your take on this. you've talked to a lot of these providers. why do they believe these laws are not about women's health?

>> thank you for having me. i'm really quite surprised to hear the opinion that the lauls were in response to the tragedy of gosnell. that koont be further from the truth. what is actually true is that four years the anti choice movement has been targeting providers. so you've slowly seen clinics start to close. on the gosnell's case there were plenty of laws because bu this they were not in use. i followed - over the last couple of years i spent time in more than six abortion clinics over a number of years and i saw the conditions in those clinics and i saw the women that were seeking abortions. i also say what is born out what is born out in the literature is

that abortion is an incredibly safe procedure. what these laws are doing is making it more difficult as your piece said for women to access a safe and legal procedure. they're not improving women's health. abortion complications are somewhere less than 2%, a recent colonel foreign i can't study found. transfers to the emergency room are less than 1%. so these laws are focusing on abortion providers and not focusing on similar outpatient procedures such as colonoscopy or cosmetic procedures. i think it is quite clear. it was quite clear from my filming and the research we did that the laws are targeted by states that seek to eliminate abortion. i think it's really distressing to see this political process

politicizing women. what we're talking about is politics and not what is helping women women's health and whether this is protecting women's health, operations that have a greater rate of can be complications, there has been research showing it is a low implication risk to do one of these procedures. can you describe why this is better? >> i disagree it is a low risk because the two greatest risks are per for eightd-- perforated uterus and haemorrhaging. without wanting to lose a child, i started haemorrhaging. if you have a pill or something at home, there is a real chance that you could start

haemorrhaging why isn't the medical association saying these are necessary things. we haven't heard that. >> i don't know. it was interesting because in 2012, i believe, william salitan who is pro-choice, had a big web series of articles called the back alley and he said because of the politics, and i agree because of the politics of abortion, people in the pro-choice side are afraid to have these laws and they're circling the wagons, but the fact is there are 3500 almost women from texas who filed a brief for this texas law who said that they were injured by abortions and clinics, and there are at least 400 women who have died from legal abortions. my concerns as a woman, and i consider myself a pro-life feminist, are we sacrificing

some lives for this cause that we want the women to have a right to the abortion. it is the poor women who suffer because in these clinics it is the poor women who don't have a choice, who end up going to clinics that are not regulated. i think we should be able to agree and have really strenuous health guidelines. one of the reasons that the women in the gosnells clinic died was because there wasn't highways enough to get a gur knee out-- gurney out. these are just simple-- you talk about poor women being affected, but in reverse we've heard the idea that if they don't have access to the clinics, where are they going to go. al jazeera did a piece that looked at a woman that went to mexico and did her own and didn't have it under the guidance of a doctor. i just want to hear your

thoughts on that. >> yes. i think a number of ideas are being conflated here and giving a misimpression. we're not talking about whether clinics can be regulated at all. they are and have always been regulated. we're talking about a specific set of regulations, many of which have gone into place since 2010, since conservative legislators have come into place that are targeted to close abortion clinics, targeted to close the places where board certified medically trained professionals are providing a medically-necessary service. there is a reason why the american association and others have come out against these laws because they're not helping health and safety. for a person that is haemorrhaging, the reason that people are having the bigger danger is when people are taking medications not under a doctor's supervision. these are women who are unable to access a clinic and taking

matters into their own hands. we are coming back to a an incredibly dangerous circumstances. i hope the court will look at the facts. i'm not aware of the death previously, but 400 deaths over 1973. every study that has study abortion in america has concluded that it isn't one of the safest. so the idea that these are not medically necessary has not been born out. what is the real purpose behind these laws if the law is upheld, does access become a function of your zip code? >> i would say that i am por-life so i don't think abortion is good for women either and there are good

medical centers and pregnancy centers in zip codes who will help women. abortion doesn't solve the problems of poverty or abuse. the clinics that i know that the pregnancy centers who talk to women in crisis pregnancys try to help them find solution to their lives, but i would challenge people on the pro-choice side to get together and compromise, have really good clinics in these areas, work to make them good, so that they can't be found faultless and that women don't get hurt in them. >> i just want to say thank you. it will be interesting to see what will happen in the supreme court this week. thank you both for joining us. >> thank you before we go, here is a look at other stories we will be watching in the week ahead. the company clear channel outdoor plans to announce monday

that it's partnering with cell phone carriers to track people a's travels. obama will be discussing a new supreme court nominee. republican leaders they will tell the president in person what they've been saying for two weeks, that their party will refuse to hold hearings on any candidate he nominates. scott kelly and astronauts will return to earth nearly a year they went to space. they set a record on staying at the international space station. the california drought has the business community coming up with new creative ways to grow produce with as little water as possible. next, the so-called blue rev lyings and the unusual ways to produce-- revolution-- foods during a draught.

# much nicer temperatures. >> reporter: it has been a beautiful weekends across much of the east as well as the south. we really needed this. there was a lot of cleaning up to do. first of all, take a look at the temperatures that we have across the region. the temperatures come down. we got up to about 60. washington was at 56.

down towards the south we saw dozens of tornadoes. a lot of good weather down here for the clean up efforts that are going across the region. over the next couple of days we have changes that are going to come been. first of all, those temperatures are going to stay nice. what you do notice here is more rain coming into the forecast. by the time we get to tuesday, that is going to be our big weather day which will extend into wednesday as well. what we do expect to see is rain from great lakes down to the gulf coast. this red area is where we expect to see severe weather going on across that area. we're going to watching that very carefully. as we go over here towards wednesday, that severe weather in the same places that we saw severe weather last time is going to be an issue across parts of mississippi, alabama. we will be watching that

carefully. out here towards central part not looking bad. for new york a nice day tomorrow at 60 degrees. a hint of snow in the forecast by the time we get to the end of the week. so friday, 36 thanks. california's drought is forcing some industries to think outside of the box. for the state's all important agriculture sector, that means more ways to grow food while saving water. a blue revolution it is being dubbed. >> reporter: these flopping, slippery fish could be the key to growing food in the future. ken armstrong and his partner jessica pattern have improvised their way to be two of the world's experts in a very different kind of farming >> reporter: did you know anything about fish going into this? >> no. i didn't. i killed my first fish tank. i've killed thousands of fish. >> reporter: do they bite? >> no, but they do jump

>> reporter: it is called aqua ponics, where plants are grown entirely in water. no pesticides, no soil, just plants and moisture. it is an ancient practice refined over the centuries from farmers in the middle east and mexico. >> essentially we're bacteria farmers. so it's the bacteria. plants know how to grow, the fish know what they're doing, so it is proifl the right environment >> reporter: it is a closed loop system. water travels through to the plants and back to the fish again. it saving water and compared to conventional alkilogramry culture-- produce, they'res grow faster. >> if you think of a big build, a one block could probably feed the entire city of san francisco

in a one square block radius. >> reporter: they get food out of a compressed space, but it is still only the equivalent of a five acre farm. to make money farms have to be tens, sometimes thousands of acres and so the question is how big can this system get. >> reporter: the food output will have to double by 2050 in order to feed the population. farmable land will be cut in half by cities. perhaps this aqua ponics could help. nobody has tried grain or r ice or other fundamental foodstuffs that keep the world alive. it requires a ready supply of electricity, a greenhouse and start-up funding for the pipes, tanks and pumps. that makes it impractical for the hundreds of million farmers
