>> how much money do you owe people >> around $350,000 >> praying on the vulnerable >> i have nothing to hide, if i was a scam artist, i would have cut and run from here >> surrogacy inc. an american tonight investigative report only on al jazeera america hamas rejects a peace plan from palestinian partners as israel knocks out gaza's main power source for hospital, sewage and water. i'm antonio mora, welcome to "r, that and more ahead. -- welcome to "consider this", that and more ahead. dead. >> conflicts in gaza enters a fourth week. >> 100 have been killed in israeli air strikes.

>> several rockets blew from gaza to central israel. >> it's a grim day in the war. >> government's rules of putting people on the terror watch list. >> they can put people without a connection to terrorism. >> the idea of how to predict who will commit terrorism is flawed and upproven. >> united states is joining the european union in imposing new sanctions on russia. >> the u.s. not happy with the russian role in eastern ukraine. >> the sanctions will have a bigger bite. >> new theories suggest that dinosaurs died off because of their timing. due to rising sea levels and volcanic activity. humans would not exist. we begin with another ceasefire offer that has come and gone in the middle east. but this time it was proposed by the palestinian authority, and rejected by hamas.

so much for the unity government. meanwhile we are seeing the heaviest fighting since the conflict began. israel hit gaza, knocking out the areas only power plant which powers hospitals, water and sewerage systems. the israeli military system said it hit hundreds of targets, a hamas television station, and the homes of top leaders. palestinian health officials say more than 120 people were killed on tuesday alone. in israel five soldiers killed early tuesday morning, after gunmen used a tunnel to cross the border. in cairo the mediators were at work preparing a proposal for ceasefire, while john kerry fought back about criticisms that his efforts favoured hamas. >> i have

taken hits before in politics. i'm not worried about that. it's not about me. it's about israel and their right to defend themselves. >> joining us from gaza is al jazeera correspondent nick schifrin. it's hard to keep track of who is calling for a ceasefire and backing away interest it. is there a growing slit among palestinians, after they proposed a ceasefire, and hamas said no. >> i think what this is evidence of is of a bit of a split between the palestinian authority, fatah in the west bank, and hamas in gaza. we knew that that existed. what, perhaps, it the larger point here is simply that it's not clear who is in charge in gaza. it's not clear if one person or one group is speaking with one voice. what we had today is a senior member of the palestinian authority coming out and suggesting that everyone had agreed on a ceasefire, including hamas, about five minutes later, the spokesman texted everyone

here, saying she doesn't speak for u saying he's not fighting, part of the resistance as they call themselves here, and we'll be the ones to declare a ceasefire, and only we. >> that happened and you have a sense that within gaza itself, and within the palestinian factions of gaza, between hamas and jihad and smaller groups, there's not ninan imenty at -- unnan imenty at all. that is something we felt, but is coming to the fore as the diplomatic process increases. it's not clear how or who can convince hamas. who and how hamas can be convinced and other groups, to go for a ceasefire. >> israel hit israel hard you were on the air a few hours ago when there was an explosion behind you. the army said it hit hundreds of targets, but gaza stds power

plant -- gaza's power plant. what does that mean for a humanitarian crisis. >> we had three sets of targets. the first is the symbols of power for hamas. you saw the top hamas official. hamas is number two, his house destroyed. three warning shots, neighbours told us we were thrown into that house before the actual strike. so he wasn't there. it wasn't designed to kill anyone or put pressure on hamas. also designed to put pressure on hamas is the strike on the one power cried that gaza has going, the one power plant, operating at 20-30% before, we had 3-4 hours of electricity throughout gaza strip beforehand. now we have nothing. you can't see anything. that's not because there's nothing there. that is because all of gaza city is really in a blackout right now.

that means more than power, water can't getpumped into many homes. people don't have water. sewerage is not treated properly. we saw scenes of suage flowing into the -- sewerage flowing into the mediterranean sea. hospitals - we are short of drugs, and they say they are running out of power. they don't have enough gas for the generators, and it adds up to a humanitarian crisis. the u.n. says there was a humanitarian crisis. the hit on the electricity station will increase na. >> thousands of people injured. good to have you with us. >> we are joined from our studio by joshua. a fellow at john hopkins school of advanced study, the author of "making david into goliath - how the world turned against israel."

great to have you with us. i want to start with crit. >>, john kerry's efforts to broker a ceasefire. you wrote kerry's performance on gaza was anything but shocking to anyone who studied his attitude towards enemies and aggressors. do you not thing he had the best of intentions. what did he do wrong? >> i am sure he had the best of intention, but he has - he always gets it wrong. he has - u.s. policy, all the way back through the cold war years, and after, and he got it wrong here. the point was that there was a ceasefire proposal on the table. it had been there from egypt. he, instead, turned and worked something new with hamas's main backers, with turkey and qatar. and the point of this proposal

was to give a bunch of sweet ners to hamas, which had rejected all the other ceasefires. so that the ceasefire would come along with giving hamas a victory in the war. and the foolishness of that was that it - it would be a guarantee of more wars, and very soon, because it - in essence, it rewarded hamas for starting this one. >> a pew poll this week looks at something that you raise in your book. it found that 40% of u.s. - 40% of americans blame hamas for the current round of violence - only 19% blame israel. there's a big partisan divider. they overwhelmingly support israel. democrats are divided. 26 blaming hamas, 36 blaming israel. 35% thing the response is excessive as opposed to 31 who

think it's right. >> in your book you say how israelened from underdog to demonizing israel. >> in this conflict and the two others before it, where the death toll is disproportionate, is it a big part of the problem. >> i think the imagery is part of the problem. but the death toll is asymmetrical, and the weapons capabilities of the two sides are asymmetrical. but the images that come in the midst of fighting on the television overshadow the other deeper asymmetry, which is the goals of the two sides, where israel's goal is simply to live in peace and to be - to live and let lie, whereas hamas's goal is genocide. it's to destroy israel and drive the jews into the sea. >> well, it is difficult to understand what it's like to be

surrounded by enmice at all time and have rockets fired at you. by most accounts the recent peace fire - the peace process failed because israeli prime minister binyamin netanyahu was somewhat ipp trance gent about settlements and other things, ground. >> no, oath it's right. the recent efforts failed because both sides were intronsy get. it's fair to put some blame at the door -- introns gent. i think it's fair to put some blame at the door to the israeli side. the people that broke off negotiations had taken them and the obama administration about five years to get them to ezin negotiating -- to begin negotiating. people involved before, former negotiators, warned that at this point it was too great a

distance between the two sides. while it is true that prime minister binyamin netanyahu is more of a hard-liner or was driving a hard bargain, we have had other israeli prime ministers that were more forthcoming than binyamin netanyahu, but still the palestinian side has not been ready to make an agreement, sorry. >> mahmoud abbas was seen as someone who was more reasonable than other palestinian leaders, and he has been at the forefront of the palestinians willing to recognise going back to the late '80s, recognise israel's right to exist. now with all the suffering in gaza, with all the death, injuries, now we are seeing iran, which had become estranged from hamas, iran is getting bellicose with comments made by the leader today. is this offensive on-gaza a good

strategy for his rail's international -- for his rail's international strength and long-term security. >> of course not. it had no choice. we saw it as the rocket firing started from gaza, and for days after days, israel was hitting back in a small way, and binyamin netanyahu kest saying -- kept saying and kept sending signals through egypt of quiet for quiet. if you guys will knock it off, we don't want to fight with you now. hamas insisted on having the war. i think probably because its own popularity was sinking. and it hoped to revive its fortunes in this way. once people are making war on you, you don't really have a choice about fighting back. >> again, the book is making david into goliath, how the world turned against israel.

turning to the most significant confrontation between russia and the west since the cold war, on tuesday the european union and the united states came together to impose brode economic -- broad economic sanctions on finance, defense and energy. it's the strongest action so far, coming as the white house accused russia of violating the 1987 nuclear missile treater signed by ronald reagan and mikhail gosha shove -- gorbachev. marking an end to the war. >> today decades of progress were set back. because actions were coordinated with europe, the sanctions we are announcing will have a bigger bite. >> joining us now from washington d.c. is ambassador courtney, u.s. ambassador to kazakh sustain and georgia, a former senior director for russia, ukraine and eurasia.

great to have you on the show. president obama was asked after his statement if we are seeing a new cold war. he said "no." you were involved at files in nuclear negotiations, you were a foreign service officer. after everything that happen, do you agree with the president? >> he's probably right that there's not a new cold war. i would say that there is a cool war going on. some of the atmospherics resemble the days when the soviet union ruled that part of the world. >> for example, in september 1983, the soviets shot down korean airliners, 00 klw 7. president regan demanded a public apology from the kremlin, but really didn't do anything else, cutting off grain shipments or stop arms negotiations. today president obama had a similar situation. they want to keep some productive cooperation going

with russia in certain areas, but do not want to cut off other things. they are important with iran and what is going on in syria the e.u. stepped up when it came to sanctions, joining the u.s. do you think that vladimir putin saw this coming or did he think the e.u. would put it off because it didn't want to hurt itself because of its ties to russia. >> the kremlin believed europe had different measures, and a key strategy was to stop them working together, to isolate them. what president obama and the europeans have done. they have stayed in lock stop toot. president obama -- lock stop together. president obama has taken criticism for not moving faster. this is moving forward. that's very effective. >> is it enough. russia's economy is

struggling, there's no foreign investment. >> sanctions are not enough. russia in the 1990s, and the first decade after independence suffered economic depp rifation great are than now. what is a greater risk is russians might see that he is humiliating russia by its actions, which have been not very successful. vladimir putin probably felt the success could be replicated. it was not. ethnic russians did not rush to support the really russian military intelligence officers who led the effort to take other buildings there. if the russians believe that putin is humiliating russia, and the sanctions show that vladimir putin doesn't know how to deal with the big powers, that could spell trouble for him. >> the pentagon has been looking

at how to help ukraine target rebel missile launch release. the administration has not made a decision on that. should the u.s. provide that military support? >> that support should be provided. counterbattery targetting will be useful. but more needs to be done. the key thing is providing defensive arms. a lot of specialists said europeans and the american ought to provide anti-armour, anti-air, other defensive weapons, not offensive like tanks, for example, but defensive weapons. for various reasons, the united states and europeans were reluctant to do that. >> the obama administration announced that russia violated a 1987 cruise missile treaty by testing a prohibited missile. why now.

some reports say russia has been violating that treaty for years. >> apparently in 2008 concern was raised. in 2011 there was a step up. sometimes it takes a lot of technical analysis to look into these things. there could be a political dimension. the united states sees u.s.-russian relations going worse in the near future. there's less to be lost by raising the issue now. it's not clear what happened in the late 19 '70s, early 1980s. russia started deploying ss 20 missiles intermediate raping missiles. a different kind of system. but similar range. in that case the soviets wouldn't deploy. that set the stage for a treat athat regan and gosha chof signed.

the first to eliminate a class of nuclear missile treatments. >> in the meantime in ukraine the fighting continues including in donetsk, which hadn't happened until now. investigators can't get to the crash site of ukraine. it's a terrible situation. good to see you, thank you. >> now for more stories from around the world. we begin in libya where firefighters had to withdraw from a massive blaze at an oil deepo outside tripoli after running out of water. the government requested international help to fight the fire, ignited by intense fighting. it brought down a libyan fighter shet and a group of ipp -- jets and a group of insurgents overran a base. the u.s., british and german embassies have been evacuated and some are urging their citizens to leave libya.

next, to west africa, where health care workers are battling the worst ebola outbreak in history. a man died in nigeria, the first ebola death - guinea, liberia and sierra leone. >> he had travelled from liberia to lagos. two more americans, one a doctor, fell ill. they have deteriorated and the prognosis is poor. also tuesday, the leading doctor fighting the outbreak of sierra leone died from the virus after falling ill last week. in washington d.c., house speaker john boehner ruled out a possibility of a house attempt to impeach president obama. >> we have no plans to impeach the president. no future plans. >> listen. it's all a scam started by democrats at the white house.

>> the speaker says that talk of impeachment comes from democrats trying to raise money. reportedly raising $2 million after using impeachment as a fundraising tool. to be fair, former republican vice presidential candidate called for the president's impeachment. that is some of what is happening around the world. coming up, child migrants make their case to congress in person. house. >> more than 1,000 nominated to terrorist watch lifts. jeremy on what you post could get you in trouble. >> and harmeli aregawi. >> there's controversy over a poster for a kid's movie, saying it makes light of one of america's greatest tramming dis. are they being overly sensitive.

with child migrants arriving on the border and congress days away from a summer vacation, house republicans proposed a build to produce border security, and make it easier to deport child migrants. >> we expect $659 billion on thursday, covering the expenses necessary, we believe, between now and the end of september. >> a few hours later the congressional kaukous heard child migrants say gangs forced them to leave their homes, and pleaded for help. we are joint by a congress woman, representing the 26th distribute. you have come from the kaug cues hearing where you heard stories from migrant kids and witnesses. there's a battle over how much money is needed for the

humanitarian crisis, and concerns that if congress doesn't act, health and human services would run out of money. john boehner is offering $369 million until the end of the fiscal year. is that acceptable to democrats? >> this is not acceptable. the hearing showed there is a huge need. we have to address all aspects of the crisis. speaker john boehner's proposal gives money to border patrol. they need the money, so does health and human services, the immigration system needs funds for immigration judges. we need to address the root causes that is making these children go on this very, very dangerous journey. >> you have seep that in person. you -- seen that in person. you went to the texas border,

and you said the 2008 law allowing unaccompanied central american kids to stay in the united states until they have a legal hearing about their status. you want the law to stay as it is, but republicans and democrats argue that the law is responsible for the surge in migration because kids and parents know that they'll be able to stay here. >> actually, if the theory was true that the president obama policies are causing this, why are people not coming from other areas. there is poverty in other countries. >> no, it's from honduras, guatemala, and el salvador - where there's extreme violence, causing these children to flee. >>

you wrote that militarizing borders was not the answer. president obama - some of the mun yes he is has asked for is for those purposes. >> yes, we have to look to whether there's a legitimate claim for violence and persecution. if the system were to be done correctly, we'd have the immigration judges that he need. now there's only 243 in this nation to take care of the cases. that's why they are a - there's a huge backlog and the children are not represented in court. that is not acceptable. >> you have written about theeate ricks in border politics, and you were talking about the militarization, and perry sending troops to the border, and your point is it makes no difference, because kids are happy to turn themselves in. what needs to be done, how do

you secure the border. do you need physical barriers? >> they are turning themselves in, that would not solve that problem. i do have to say that i directly asked the border patrol whether they are shipping to the border, and they said they could help with the paperwork. they are not trained to work at the border or process the kids. it's a theatrical move that would serve no purpose. >> how do you stop the flow into the united states. what do you need to do. once the kids stepped on u.s. ground, they have the rights. is there no way of stopping them from getting on to u.s. territory. >> what would help is a functional immigration system. if we had an immigration system that could hear the cases in a timely manner, we would know who qualifies to stay, and who needs to be returned back to the country. right now, the cases have such a

great backlog that it could be five years before their kids could be heard. that's not right. >> a poll from the republic institute says 17,000 unaccompanied migrant kids should be treated as refugees and stay in the country if there's proof that it's too dangerous for them to go home. are you surprised that there's that much support. >> america is a land of immigrants and it cheers my heart to know that americans have compassion to ensure kids will not be sent back. do you think anything will get through congress and the senate? >> we must push for it. because the money will run out. and we need to make sure that these children are at least kept safe. this is a land that has shown compassion to the vulnerable,

children. >> congress woman, judy chew of california, we appreciate you joke us. thank you for your time. >> the u.s. government added more than 1.5 million names to the terrorist watch list in the past five years. getting on the watch list is a lot easier than getting off, according to the national countermorism centers 2013 watch lifting guidance, an american or foreign national can be added to the list without concrete facts and evidence tying them to terrorism. only reasonable suspicion is required, for some, not that. >> we are joined by an investigative reporter to obtain the guidance document and who wrote about it in an article entitled black listed, a government rule book for thableing you a -- labelling you a terrorist. >> let's talk about the rules.

there's the terrorist database, a no-fly list, and requiring scrutiny at the border, whatever border you are trying to enter the yate through. why is the government determined to keep the secret. >> what we are looking at is a shadow or parallel legal system. we are not allowed to know what the laws are, or how we can do something that will get us cat forized as a kst -- categorized as a kst, a known terrorist. the standards that are used to place people, including american citizens is called reasonable suspicions, which is the same tender used for stop and frisk. it's like a global stop and frisk programme. it's a loose standard. >> you mentioned the lists. at the top of it you have a classified database.

you have meta data. along with sfuf from foreign governments. that is not the watch list. there are hundreds of thousands on the database. hundreds of thousand of people on that. from there you go down further. there's the no fly list, you are not to board a plane in the united states, and the select t list, which means every time you check into a flight or cross the border, you'll be pulled aside for terrorism screening. >> last year, more than 450,000 people were nominated to be on these lists. you are talking about 1,000 people a day. how is there a way to have quality control about who is on the lists. >> on the one hand you make a civil liberties argument about the policies. >> in june, a federal judge declared it unconstitutional. that there's no way for anyone to know they are on the list, and it's almost impossible to

get off of it. >> there's no review process. >> only an internal review process. the courts don't have a role. there's not a system of checks and balances. once you are sucked into vort vortex, it's almost impossible to get out of it. >> ted kennedy was stopped. >> and nelson mandela. e.v.o. morale es. the president of bolivia. i was talking to someone today, whose son had a similar name. >> if someone is on a list because of reasonable suspicion. on top of that, they are associates and family members. it's a broad group of people. >> of course, and one. things that i laughed out loud when i read it, i thought it was a typescro, it's true.

the -- typo, it's true. the subsidies -- deceased spouse dying. name. >> it sounds a little ridiculous. the problem is what - the definition of who a terrorist is, the threshold is low, in be. >> it's a one-two punch. if you are on the list, and your number pumps up in the text of someone who is a known or suspected terrorist, you could be on the watch list. if you post someone on facebook, and say this sounds like this person has sympathies towards a jihadist group, you could be on the watch list because of an uncorroborated account. you could tweet something that is sar cast ib, someone that doesn't get it locks at it and says "we have to watch the

person", and you are stuck into the machine. it's not like the government has this and if you do something wrong, it will pop up. this could be used in court proceedings, you could get pulled over. >> that doesn't strike me. you could pull - you get pulled over by a policeman, and somehow your name is checked against the lists. >> look at the cases and countries of racial profiling. it's often muslim people, arabs, pakistanis - they are being targeted. imagine if you are an arab man with a beard, driving down a county road and a sher itch pulls you over -- sheriff pulls you over because of a busted tail light. they take your name and run it, and up pops that you are a terrorist. that's a dangerous situation for that individual in the car because the sheriff is told

there may be a suicide bomber. though don't know what known terrorist moons. >> we had a former member on the show on the no fly list, and was unable to get on an airplane, restricting his ability to get work. and the float side of it. people say better safe than sorry, if someone has to go through a hassle of keeping the american public space, we have to do it. >> the average american would say that was reasonable if that was happening. >> we talked to conservative fbi agents telling us that they are drowning in information, that it's making them difficult to attract terrorists or suspected terrorists. what i think is at the heart of this is not keeping us safe. the reason they want so many names is to use as leverage informants. way. >> and to cover their butts. no one wants to be the person

whose name was not in there. the under wear bomber was not on the no fly lift. his name was in the intelligence community but his name was not nominated. after the under wear bomb plot almost succeeded the obama administration said we want all the information, collect it. they are drowning in meaningless information, trying to find a needle in a haystack. >> taking away time from efforts to combat real terrorists. great to see you. >> thank. time to see what is trending on the web. >> paramount pictures is in the middle of controversy. a poster for the teenage mutant ninja turtles movie appears to have offended some. australia tweeted an imaging of this falling from a skyscraper and the release date of september 11th. considering the parallels between the image, release dates

and the 9/11 attacks, it was an insensitive joys. rosie says: >> there were many, if not more that thought it was ridiculous that people were offended: paramount released a statement apologise are for their choice saying: >> let us know what you thing on

world history. after 37,000 hours of recordle, 5-7% were transcribed. the new book "the nixon tapes" sheds light on many taped conversations before the water gate scandal. award-winning require co-ed itted and annotated the book. thanks for joining us. israel, four decades later, dominating the headlines, and a tape you transcribed brings up an interesting issue in a conversation that nixon had with his chief of staff. let's listen. so they are talking about

henry kissinger, the then national security advisor, should be involved in middle east policy. >> keep in mind nixon had this as a voice activated system. he captures everything, the guard is down. they were worried nixon and hallederman and others, that kissinger may be pro-israel. henry comes in and is constantly trying to prove that he's not. nixon tells holderman i don't want anyone dealing with israel that is jewish because of the baked oven, world war ii, the holocaust and emotionalism. it's graphic and unusual and odd, ugly way that nixon describes that. >> you bring up the guard being down. the reality is few people knew that it existed. the few who knew it existed let their guards down. others didn't know. >> none of the guys knew.

kissinger was a going guys, a smart man from harvard, writing books on nuclear weapons, he's a great states craft people. he doesn't come out so great. >> let's listen to something that henry kissinger said when he discussed jews in russia, and the problems they had and whether the u.s. should get involved: there. >> there is a callous innocence to nixon and kes ipinger -- kissinger. they believe in politics, power. the downside is little on human rights and humanitarian concerns. and kissinger is saying let the soviet union do what they want

with jewish people, we'll turn a blind eye to it. it comes off callous. >> talking about callousness, a striking one is involving vietnam. let's listen to that. >> okay. . >> little brown people kavt rating millions of catholics. awful stuff. >> nixon had a hatred for the country of india, because they were doing business with the soviet union, and he wanted to punish the indians and backed pakistan.

we talk about nix job in his opening to -- nixon in his opening to china, how nixon did the china approach. but when he comes to india, the names he called the leader, i won't get into on your show. robert dal ebbing -- dalek, your fellow histonion -- historian criticised nixon and said the vulgar itty tarpished the -- tarnished the presidency. lyndon johnson was no shrinking violence. john kennedy himself wasn't. are we looking at the the tapes and judging them through a 20th century leps, and what is appropriate now - what was inappropriate now may not be seen like that. >> to a degree. keep in mind nixon was breaking the law. you are listening to abuses of

power, the president forced to flee the white house because that's right so much thuggery going on. they were ordering a break-in of the brookings institute to steal office. you are capturing that. bbj used barnyard language, kennedy had tants put would -- taints, but would push them when doing well or in a statesman mode. foolishly nixon grabbed everything. >> this does crapp tur some -- capture some of the brill yaps of nixon. it's after assault one, and after the rech lish -- reckless one with china. he won the election with 61% of the vote. if not for the tapes which led to his res iing nation, do you

think -- resignation in watergate. do you think you'd see him as a great president. >> ip do realise that that tas -- i do realise that's a bit like asking mrs. lincoln how was the play. >> he won is huge victory in 1968, reelected in 1962, the biggest land slide ever. he created the environmental application agency. a liberal on domestic affairs. and he had a breakthrough to china. vietnam was a downfall. unlike eyesen hower who pulled them out of china saying "game over." nixon mann ip ute lated that. the combo of vietnam and the lowest. >> i know he never expected the

tapes to go public. we skim the service. fascinating stuff in the book. later. >> 1973, then hague pulled the system out, and his presidency collapses. >> we look forward to that. good to see you. >> the book is "the nixon tapes", and it's available. were dinosaurs extinct because the bad luck. >> a shocking america tonight investigative report... >> you take someones hopes and dreams of childhood, and then out right steal their money >> wishing to start a family >> we lost over $20,000 trying to do surrogacy in mexico >> but left with broken hearts and empty pockets >> how much money do you owe people >> around $350,000

al jazeera america is the question of what killed the dinosaurs has been a long hot topic of debate. was it an astronaut or volcanos. research published friday found extinction was caused by all three tied together by bad luck and timing by the dinosaurs. don't be sad for them, their bad luck may be the reason we are here today. joining us is a paleontologist, the lead author of the ex-tippings of the diane -- extinction of the dinosaur's article that was recently published. this is fascinating. paleontologists argued about this, about what killed the dinosaurs 65 million ago. the leading theory was it was an astronaut or a comet. your finding is if that ent had happened earlier or later, the

right-hand. >> this is the big one, the big question about dinosaurs. one of biggest riddles in science, the mystery that got me hooked when i was a kid, the question of what happened to these things. we have done new research, compiled data on how dipo saur diverse -- dinosaur diversity change. the big asteroid that hit the planet was the primary reason they died out. that asteroid happened to hit at the worst possible time for dinosaurs. timing seems to have been everything in this case. >> the worst time because what - vol can uk activity -- volcanic activity created conditions where the strong. >> it's never a good time to be hit by a 6-mile wide asteroid.

but for the dinosaurs. it hit when they were in a rut. not a big rut? if you were looking at the dinosaurs, you would have thought they were doing well. but one type of dinosaur in particularly, the plant-eating dinosaurs, at the base of the food chaining, they, for a few million years underwent a little bit of a decline. there were fewer species of them. since they are at the base of the food chain, they are fundamental. the key zone species. because there were fewer of them, they were vulnerable to collapse when the asteroid hit. make if it hit a few million years earlier when there was more of the big plant-eating dinosaurs, they would have had better odds. the asteroid was the final nail in the coffin to finishing the eco system in decline.

well just pushing them over the edge because it brought a double whammy, the effect that was aftereffects. >> that's what it seems like. dinosaurs were not declining for tens of millions of years before. they weren't wasting away. that's an idea that people used to have. now, about 35 years later, after the ator i had impact -- asteroid impact, and the debates, there's so much new information on dinosaurs, we are finding a new species somewhere around the world, once a week. we are confident that dinosaurs were not wasting away for a long time, but the big eaters were declining, then the asteroid came down, you'd have had devastation, wildfires, acid rain, ecosystems collapsing. planet. >> and then combed.

so you had this -- cold. so you had this perfect storm unlucky for the dinosaurs. if that hadn't happened you today. >> i think it's the way we have to look at it. i know it can tie your brain into a pretzel, but the story of the dinosaurs really is our own. this was a cataclysm. out of that cataclysm is the opportunity for new groups of animals to evolve, to rise to dom thens, and that's when mammals had their chance. without the asteroid mammals wouldn't have the stunty, and without mammals having an opportunity, bats, whales, dogs and cats and humans would have never evolved. it's a fascinating look at incredible animals and a look at the world's history. it's a pleasure to have you with us.

thank you for taking the time. >> thank you very much. >> that's all for now. the conversation continues on the website aljazeera.com/considerthis. >> president obama says the brand-new sanctions just slapped odd vladimir putin's russia will have a bigger bite. but i see mostly bark. how america could really show its teeth and put an end to the ukraine crisis. and also, more than a third of americans have an unpaid debt in collections right now, and here's the surprising part, you could be on the list and not know it. and plus, if owning your home is the american dream, here's your wake-up call. we haven't seen a home ownership rate this low in 19 years. i'm ali velshi, and this is
