join us next time on "techknow". go behind the scenes at aljazeera.com. >> this is aljazeera america live from new york city, i'm tony harris. dozens of desperate journeys now ending in death, the refugee crisis. fives days after nigerian girls were kidnapped by boko haram, the families say they haven't done enough, and tep years after hurricane katrina, president obama said that much

more must be done to prevent a disaster. >> we begin with a refugee crisis in europe. they met to it discuss it. and as they met, there was more tragedy. bodies of dozens of refugees were discovered in an abandon truck, east of vienna, and in the mediterranean sea, at least 30 people were killed as a boat sank. dozens were rescued. at least 340,000 refugees landed in europe this year. many travel the route that crosses the central and the east and them make the trek through the balkans. the refugees head to prance and britain and other countries in search of better opportunities and a better life.

we have two reports for you. >> reporter: it looks like nothing out of the ordinary. a truck parked on the busy road leading into ver vienna, but ths is the scene of a crime. when the police approached, the dry was nowhere to be seen, and they saw blood seeping out of the back, and they were overwhelmed. [ audio difficulties ] >> our apologies. no idea what happened. but we'll get that fur. one nation has been very clear about its intention to stop thousands of refugees from traveling through its territory. hungry is building a huge fence along it's border with serbia to keep people out. but many are finding ways to get around it. >> reporter: this is the 3 and a half meter high fence that separates hungry from

serbia. it's controversial for many reaches. it has cost millions of u.s. dollars, but many are cutting it with razor wire, and getting over and cutting through the fence, but there's another problem. the fence comes to an end just here, leaving a wide-open space. people walk in from serbia without interruption, and you can walk back in. what's the reason? when i walk backwards, i'm coming into romania. you can't put up a fence or wall between two eu states, and therefore, you have this anomaly with people being able to walk through three different countries. the nearest hungarian town is over there. and the locals have sympathy for the refugees, but anger towards the hungarian government.

>> it won't solve the situation, it's not for the migrants. the government wants to prove that they're saving the country. >> within a few minutes of our arrival, the hungarian border police did arrive to ask us questions, and within minutes, they asked who we were, and they even tried to explain the lay out of the land. they prefer more suitable areas of the town, and when the fence is completed, this problem will always remain. potential hot spots, and places that can be exploited by criminals. an example of the problems that the eu faces in policing it's borders. >> that's andrew simmons, and let's get you back to vienna now and barnaby phillips >> reporter: it looks like a truck on a motor way leading

into busy vienna, but this is the scene of a crime. when the police approached the abandoned vehicle, the driver was nowhere to be seen. they saw blood seeping out of the back, and they were overwhelmed by a terrible smell. inside, they found the decomposing bodies of people who had been locked in and suffocated. we don't know their country of origin, even counting them is a slow, gruesome task. >> reporter: how many people were in the truck? at this point, i can't tell you example. it might be more than 20 people, 20-50 people transported in the truck is all of them have died. it's very likely they're refugees, and likely this they're trafficked from east to west. >> reporter: the summit in vienna was always likely to be the refugee crisis, but this

gave a grim tragedy to these talks. >> we are very much shaken by the news that up to 50 people lost their lives in a situation where criminals facilitating an illegal border crossing did not care about them, even as they're on the way to places where they thought they would be safe. we need to tackle the issue of immigration. and today, there are more refugees than in the second world war. >> the austrian and german chancellors say that they want to move quickly to a system where european countries commit to taking on a certain number of refugees, depending on their size and economic ability. it would be fair, but certain countries such as denmark and the uk say that they will have nothing to do with european refugee crisis. suggested by the european

commission back in may. at this summit, the eu officials called for governments to have the courage to take difficult politicalling decisions. >> these people come to europe for protection, and they need europe to protect them. and we need to live up to our standards of human rights and respect for international obligations to protect them. we need the european approach, and everybody says so. >> reporter: the leaders also discussed ways of helping balkan countries cope with the influx of refugees, and to help people stay in their countries of origin. but that's a long-term solution, and there are no immediate solutions to europe's refugee crises. >> back in this yee, a vigil for the reporter and cameraman who were shot yesterday is about to be underway outside of

the station they worked. for alison parker and adam ward, at the exact time that they were murdered during the live interview by a former colleague. parker's father said that he will now fight to end gun violence. >> i'm going to to do everything that i can to make sure that her life has meaning, that people remember her, and that we don't have another new town, and we don't have another movie theater shooting, that we don't have another charleston. the politicians have got to stand up to the nra and close some of these loopholes so the crazy people don't get guns. >> adam ward's fiance, a producer at the station said that it has turned her life upside down. the shooter shedding a spotlight on workplace violence. and often it can erupt with no warning. bisi, how common is workplace

violence? >> reporter: tony, workplace violence say very serious problem. every injury hundreds of people are killed on the job. this afternoon, i had the opportunity to speak with a labor attorney who says that workplace violence is an issue that every company should evaluate. september 24th, 2014, joe, a recently fired ups employee, guns down two employees before killing himself. the next day in oklahoma, alton nolan, after being suspended, returns to the von food processing plant where he works, beheads an employee and stabs another. alison parker and news photographer, adam ward, carried out by a former coworker, one with a history of incidents that led to his firing. >> eventually, after many incidents of his anger coming

to the fore, we fired him and he did not take that well, and we had to call the police to escort him from the building. >> reporter: tw two hundred cases of workplace violence are reported every year according to osha. according to the bureau and statistics, workplace killings like the one in virginia are rare. 14,000 people were murdered on the job between 2000 and 2012 and that averages out to 700 violent deaths a year, and the shootings make up the lion's share of those deaths. in 2002, gun violence, while the number is declining overall, the government data said that there has been a rise in the attacks in which the assignment is a colleague or a former employee.

labor attorney, john hancock said that the workplace violence in the united states has been a problem for many years. >> we're taking more note of it. and there has been more publicity about it. and given the te tenor of the community now, we're appalled even more than we were before when it happens, especially the randomness of t. >> and it's that randomness that hancock said needs to be addressed with a plan that might prevent the next tragedy. >> i think that employers need to be aware of it, and they need to train their supervisors, and they need to have an escape plan, and practice that. >> because you don't get a chance to make it work a second time if you don't get it right the first time. >> hancock said that the most common types of workplace violence involve bullying and intimidation. oftentimes those incidents go unreported and that's something that needs to change.

>> bisi on the air for us, and thank you. and the dispute at an iranian facility could put the deal with iran at risk. the watchdog said that the iranians may have built a site, and the iae said that construction material has been there since may, and activity at the site has made it difficult to know if iran conducted nuclear bomb detonations there a decade ago, and iran calls it fabricate. police in china have arrested people conjunction with the maxive explosions a week ago. and at least 145 people were killed in the blast. adrien brown has more information. >> reporter: in a sense, those who you would expect to be arrested have been arrested.

they include the chairman, the vice chairman, and at least three of the deputy managers where all of the chemicals were stored and where the explosions happened two weeks ago. on wednesday, it was announced that the man who headed the safety regulator had himself been killed. he was a former deputy mayor of tianjin. and you get the sense that this investigation is going to be more open than previous similar inquiries. in the past, they tended to be very opaque, but this time, the authorities are much more open with the information that they are releasing. but we still don't know the answer to several key questions. one, why is it that so many dangerous chemicals were stored less than 800 meters away from where people were living. chinese law states that such chemicals have to be stored at least 1,000 meters away.

most of the dead are firemen, and the question is why were they trained to deal with something on this scale in and why did so many firemen die? and the regulations to tighten the regulations governing the storage of such chemicals. >> it has been 500 days since boko haram fighters broke into a school in nigeria and kidnapped girls, and most of the girls are still missing. the families of the girls are gathering. >> her daughter is one of the 219 missing schoolgirls. esther refuses to give up hope, taking part in a march to mark the grudge marker. >> i don't think that it would be this long. we want the government --

[ unintelligible ] we don't want any people dead. she's leading the march, and she's on the forefront of the campaign to put pressure on the government to rescue the girls. >> there are 219 girls out there, and quick not afford not to continue it. every day we are here, we say not until our girls are back. like i've always said, they are our daughters. >> reporter: but the girls have not been seen since they appeared in this boca raton video last year. nigeria's new president said that his government will not stop looking for them. >> [ unintelligible ] -- a

location in the northeast. i think the intelligence that was very -- it went into something deeper, clearer and more specific. >> reporter: the president met with some of the relatives and campaigners in july to personally reassure them that the government is doing everything possible to bring the girls home. the government said that it can't help relatives and campaigners whether it knows if the girls are still alive or where they might be because it might put them in danger, but every day that the girls are missing, the parents are losing hope of seeing them again. >> ten years after katrina. >> i have never been more confident that together, we'll get to where we need to go. >> president obama visits new orleans, which is still rebuilding. a look at the promises he has made and the promises he has

kept. and plus, gathering rice off the reservation. why a native american tribe could be prosecuted for doing it.

>> a native american tribe is putting an 1855 treaty to the test today in minnesota. members are gathering wild rice outside of the reservation, a

right that they say they are guaranteed by the treaty. and if they are allowed to harvest the rice, they say that they should have the right to other uses for the land. diane, is this just about rice, or is there something more going on here? >> reporter: no, it's not, tony. this is part of a very long battle that the chippewas have been aging over treaty rights that they signed with the federal government over 200 years ago. they say that the state of minnesota will not acknowledge those rights, and now this whole dispute is being complicated by a proposed oil pipeline. the plan was so devise state rules about gathering wild rice, but it was subtle before the chippewa tribe members. >> the department of natural resources, harvesting the rice. >> i'm glad to see that. and everybody else is glad to

see it too. >> the tribe member wasn't, he tore up the special one day permit. >> we never requested this application, and never applied to it. >> the chippewas wanted to be ticketed so they could challenge the state in court. they say that minnesota is ignoring the treaty, allowing them to hunt, fish on hundreds of land they ceded to the government. rice is a stap until the chippewa culture, but it's more than that to thompson and his son, todd. >> this is a spiritual thing. >> reporter: they fear any potential rupture in the pipeline could destroy a way of life. >> all of these lakes are like a spider web. i don't care where you go in minnesota, they're all connected. and any oil that ever breaks down and gets in our water, our rice is done.

it's done. >> reporter: some members were disappointed that a possible confrontation with the state is diffused for now, but it cait could be a sign that the minnesota officials are listening to them. >> they believe that they need our consent, because if we have property rights, they have to be dealt with through the due process clause, because we have a treaty. >> reporter: tribe members say this they will come back on friday to harvest the rice again, but they may not get the welcome that they received on this day. >> this is the one day permit. >> this is a one-day permit. >> it could be tomorrow -- >> the officers to enforce the state regulations on all people. >> reporter: now, the tribe said that it sent a letter to governor mark dayton, asking him to acknowledge the treaty rights, and the tribe has not

heard from the governor. and we put in a call to the governor as well, and we haven't heard from him either. >> all right, diane eastabrook, thank you. on some native american reservations, the members are fighting another battle. same-sex marriage equality. many of the tribes have their own laws banning gu guy marriag. >> tradition, the law of the land on navajo nation. a society in which the family is the foundation. >> the core of what it means to be navajo is compassion and family and being accepted >> reporter: 29-year-old nelson is the only son in a large navajo family. and he remembers his childhood fondly. >> it was probably the best part of my life, because i had

so many cousin brothers and sisters, and we live in a very rural area, and all of this land to explore and ride horses, to build mud houses and to really be outside. and i always remember doing that growing up. so it's important to me, that if i plan to raise a family in future, that my own children live that happy time in their lives as well. >> but the dream of building a family of his own and one day raising a child in a legally recognized family is out of reach. for ray and his partner, brennan, marriage is still banned by their government. >> it says marriage between persons of the same-sex is void and prohibited. >> alray is reading a portion of the 2005 marriage act, a law which denies him the right to

marry, despite the supreme court legalizing same-sex marriage earlier this sper. >> summer.>> i want the tribas to know that it's foreign to them. but it's navajo law today. >> the laws vary greatly, depending on which reservation you travel to. sovereign native native tribes still have bans on same-sex samx marriage, including the largest, the cherokee and the navajo. combined they have some 6,000 members. and alray is leading the charge to change navajo law, but so far, his attempts have failed. >> with these here, we need 16 votes to repeal the law, and we have a long way to go. >> reporter: our request for comment from the navajo

president, ben shelly, we went unanswered. with the laws changing across the country, alray feels that his tribe will have to come along eventually. aljazeera,nastic hoe nation. >> and you can see more on that at 10 p.m. eastern. 7:00 pacific. the best it has ever been. the army corp of engineers has good things to say about the new levee system in new orleans, but first, how climate change is killing off an already endangered species.

ga

>> two days from now marks the 10th anniversary of hurricane katrina. the hurricane that devastated new orleans. but the big easy has bounced back in a big way. the president went this, and saw how many people rebuilt their lives, and he said that their resil yes is an inspiration. >> because of u. the people of new orleans, working together, the city is working in the

right direction, and i have never been more confident that together, we'll get to where we need to go. you inspire me. your efforts inspire me, and no matter how hard it has been, and how hard and how long the road ahead might seem, you're working and building and striving for a better tomorrow. >> reporter: jonathan martin is live in new orleans, and the president made a point of visiting one of the oldest african-americans, not only in new orleans, but in the country, and this is a neighborhood that was devastated by the floodwaters. >> reporter: the president made it a point to go to several of those neighbors, and here in the 9th ward, he spoke at the $20 million community center, but before that, he rolled up his sleeves and walked through the neighborhoods. tremaine neighborhood and the lafitte be neighborhood. and some of the people wer eageo

show him how they rebuilt their lives. but as many remember, that was ground zero for hurricane katrina, and while we have this brand-new community center here, there's a new fire station here, and it opened about a year ago, and the school across the street from us, there are residents in the community who have not come back, so when the president rode in today, there were people standing on the streets of the ninth ward clapping and applauding but understand that there's a lot more to be done, tony. >> how were the president's comments and speech received? >> reporter: overwhelmingly, i think that people were pleased with what the president said. as you heard from the president earlier, he was really applauding the people, and talking about their resilience, saying that he was inspired by them. but one of the things they were happy to hear, they were happy

to hear that the president was honest about the people of new orleans. saying that 80% of the population has come back, but also saying that we have a long way to go, and there are a lot of people in the city still struggling. >> our work is not done when there are so many people who have yet to find good, affordable housing, and too many people, especially african-american men who can't find a job. not when there are so many people who can't come back home. >> and so many of the numbers speak to how bad it is. 70% poverty rate. and 62% of black men in the city don't have a job, and the president pointing out that there are still challenges, but also taking the time to count the work of his administration when it comes to building hospitals and schools, and the biggest thing perhaps of fortifying the levee system,

and pushing congress to get the $14 million to get the city better protected, tony. >> well, tomorrow, and can't wait until tomorrow, actually, but former president, george w. bush is set to visit new orleans, and what can we expect? >> reporter: it's to be seen. we know that former president bush is visiting one of the cities, premier charter schools, highlighting how the education has changed since hilliary clinton, and they have one of the biggest charter schools in the country, where 93% of the kids go to charter schools, but we all remember back in 2005 where many people feel that the bush administration did not respond. we remember president obama flying over new orleans, but not stopping here on the ground to talk to people. so i spoke to 10 or 12 people today, and it's overwhelmingly, people ten years later have a

hard feeling about that, and they're angry and upset about that, and they're not happy that he's coming tomorrow. >> it's hard to forget that minimal, the president in airforce 1 flying over. jonathan martin for us. bob jacobs is a specialist who joins us from baton rouge, and let me get to that. is today's new orleans better prepared to handle a katrina type storm than it was tenning years ago? >> oh, absolutely, yes. you know, the system has been built after katrina is everywhere higher and stronger, and when the armoring is completed, more resilient against breaching than katrina system. so we encourage people to move to new orleans, and they can rest assured that the system we have today is better than the

one we had ten years ago. >> i want to ask you specifics on that, but let me ask you a followup on that. how about the lower 9th ward? >> well, recognize if you've been to the city, that the levees have three distinct areas. and the lower 9th ward is behind some of the strongest features. ironically, it's the slowest to come back for other development reasons, but the particular structures, we refer to them as t walls, and these particular flood walls are much stronger than the walls prior to katrina. but i want to say that even though we have a system that's stronger than before katrina, there's a little bit of irony. the system is purposely designed and designated to protect property only, to protect property from flood damage, and not there to protect lives. so the key component for

hurricanes in the city is complete evacuation. and that's for anybody in the area, to get people with health or other issues, to support them in evacuating, so the real story, going down the road with hurricane surge threats in new orleans, the levee system is there to protect property. and it's going to be reassessed and reaccredited every ten years by people fema, and people to have their flood insurance, just like fire. you have to have your flood insurance, but the people, we want to make sure that we have good evacuation. >> i'm trying to read through the lines of what you're saying here. are you disappointed that the rebuild is not doing a better job protecting people? it does a job of protecting property, but not people? >> . >> absolutely. i grew up in the area, and

obviously those of us who care about these urban areas, whether it's baltimore, or miami, we is the urban areas threatened by floods to have higher standards than just the 100-year flood. but even folks who have begun reviews at the federal level and the national academies have said that really, a 100-year property standard levee system is not adequate. but in the wake of katrina, to hurry up and stabilize property values. they knew that would be the easiest thing to do first, but unfortunately, there has not been a commitment on the part of congress, or the locals or the state or anyone saying how do we raise the system higher so we can further reduce the

risk to property beyond the 100-year storm? i don't think that new orleans would be the place where you would want to take the bet and stay. but certainly, we would like to see no breaching in the system. that would be the main thing. a little bit over the topping we can handle, so the more resiliency and the more height the better. >> bob be jacobson. he's an engineer joining us from baton rouge, thank you. and another reminder for you. make sure that you tune in tomorrow evening for katrina after the storm on aljazeera america. tropical storm erika weakened slightly today. but it pounded the caribbean island of dominica where four people have been killed. and it's expected to hit the united states early next week. by then it could reach hurricane status, according to the u.s. national hurricane center. and kevin corriveau sells us

what's in store with erica pitzi. >> we're seeing it makes it way across the virgin islands and towards puerto rico. the storm is slowly increasing in intensity. but we don't think that it's going to be a hurricane until it makes its way to the bahamas. this is what the national hurricane center is da saying on the placement in the next several days. by saturday, it's going to be to the north of hispaniola. and then it enters into the bahamas, and it's at this point that we begin to see some uncertainty with the storm. we think it's going to stay a tropical storm, but it makes its way toward florida, it could be potentially a category 1 storm. the longer the storm stays in the open water, very warm water, the chance that's it's going to increase in intensity. as we go to monday and tuesday, we are watching carefully, because we think that it's going to make a turn to the north, affecting parts of georgia, and maybe even north

carolina. so we are watching later on, toward the beginning of the week, this deep trough could push it over, but we're going to be seeing initially quite a bit of flooding. >> in idaho, sock-eyed salmon have been dying off by the hundreds, and the river is warming up. that makes it tough for the cold water fish to survive. >> reporter: so it's 8:30 in the morning, and temperature levels are already almost 22°, which is above 07°, the mortality level for the sock-eyed salmon. >> salmon spend the most of their lives traveling up and down the river laying eggs, and those eggs become fish that return to the ocean and make the same journey again. now the climate is changing everything. the hazy quality to the air

here is wildfires, and you can smell the smoke in the area because a few miles from us is a 65-acre burn. and it's all function of climate change, and that's having a terrible of course on this river. >> i monitor temperatures up to 78° along these stretches this summer. and at this point, from a scientist's point of view, and from an endangered species point of view, as an attorney, this run is functionally extinct already. >> reporter: salmon are cold water fish, which means that they need more oxygen than other species. as the water is warmer, it holds less oxygen, and the fish begin to die. salmon have been on the endangered species list before climate change as way problem. some people believe that the

dams are also making it harder. there are eight of them over the course of the 900-mile journey that the fish travel. and that extends their travel time from 608 weeks. during that time, they have to transform as beings, going from a saltwater fish, fresh water and back again. and when you have to blow that much energy over a couple of months, as opposed to two weeks, it takes a terrible toll on your organs. so far this year, by the time the sock eye reach this fourth dam, run by the army corp of engineers, their official numbers go to 414 fish, a drop of 60%. >> all of measures and the billions and billions of dollars they have spent to try to allow the dams to stay continue operating as they always have, has been to the

peril of our fish. >> steve pettit was a fish biologist for fish and game, and spent 32 years trying to negotiate safe passage for the fish at the dams. >> you don't think that there's any way -- >> i do not, especially when you enter climate change into the picture. >> reporter: when the migratory season ends, as the climate changes, the snake river, which once hosted life and death in the cycle, could soon be entirely unliveable. >> the u.s. economy grew faster than expected. and the american unemployment rate is 5.3%. but it's significantly higher than the so-called millennials. 18-34. what's in the study, ali?

>> well, as you said, the young adults, the millennials, was 7 and a half percent in july. and the population percentage rate, 5.3%. so more than 2% higher. advocacy group, young invincibles, many of the jobs are in low wage sectors, and they are trying to determine the best jobs for this group of young adults. based on factors like pay, the field's projected growth. and the share of young people working in each job, and get this, the best occupation for young adults is physician assistants. it has a median income of $91,000, and actual wears took second place, and a tie for third between statisticians and biological engineers, and then stem jobs, and additional five jobs in the medical field,

therapists and dental hygienists. >> anything in the study stand out for you some. >> number eight on the list of best jobs is people who install and repair elevators. they have a medium income of $76,000. and in my case, i get less nervous every time that the elevator stops between floors, and the job growth in the elevator technician field will be 20%. i don't understand it. i'm going to guess because society is aging, and they're going to use elevators more than stairs, but the top paying on the list, petroleum engineer, $130,000. that's the median annual salary. that's not starting, but that's still in the high 90s. remember, not all high paying jobs are realistic for a young person. and that's why they removed

from contention the jobs that are the most selective in the future. and petrochemical engineer, these were before the lowering of oil prices. what are we looking at for the show? >> we're looking at new orleans after katrina, and specifically, how changes to the health system may effect those with mental health issues. >> ali, good to see you, and you can watch ali velshi right hoor on aljazeera america. >> just days before america's grand slam ten is tournament. my conversation with katrina adams, the first player to head up the u.s. tennis association and the u.s. open toy. >> plus: 6. >> i'm paul brennan, the first an verse edition of the record book itself.

>> the fastest man could not outrun the subway. you see it as they celebrated the 200 gold medal. it ran him over but he'll be fine.

and perhaps his rival, u.s. sprinter, justin, paid the cameraman to run him over. next week, tennis, i spoke to the president, katrina adams, and she told me that serena williams could be the first woman to win a calendar year grand slam since 1988. >> what serena has done, she has won the serena slam twice, four consecutive majors, just not in the calendar year, and she's the defending champion. so speaking to her earlier today, her focus is defending her title, that's first and foremost as a defending champion, and if that happens, she'll be the calendar grand champion for 2014. >> if she does that, is she the greatest -- i was going to say female athlete -- is she in the

conversation for being the greatest athlete america has ever produced? right up there with ali and ray? >> i would say so. because of the longevity of her career. you have to look at the span of how long she has been out here. how many weeks she has been number one in the world and when you look at her record this year, she only has two losses. and to go into the tournament, if she's able to win, for sure she could have that title. but even if she doesn't, i think that she deserves it. she's phenomenal. >> what are your thoughts on what she's attempting to accomplish, particularly given your background as a former player. how out of sight is it, what she's attempting to do? >> i think for what she's doing, obviously it hasn't been done since 1988, when stephi graff won, and then before that -- it has only been done

three other times. >> calendar year slam. >> for other women. only three other players hold that honor. >> so what does this week feel like for you as the first former player, the first african-american, to sit in the chair you now sit in as president and chair of the board of the united states tennis association? >> it has been fun, actually. it has been very busy, and a lot of different activity every day, with meetings leading up to the tournament and what we're expecting next two weeks. >> you went to the new york stock exchange yesterday. >> that's right. >> can we thank you for the surge and the rebound of stocks yesterday and. >> of course. i have everyone saying, can you go back tomorrow and the day after that and that? >> what was that like for you? was it good? >> it was good. >> you have never done anything like that before.

>> i have not. >> what does it mean for you to hold this position. >> it means the world for me. as a former player, coming up from high school. >> chicago. >> chicago west side. played on the tour for years, and being involved as a commentator, i have so many relationships within the game on so many different levels, and to be able to come out and understand what many of our constituents are feeling and experiencing, and try to execute to make the sport better, it's amazing, but also to be here in this seat if and when serena williams wins, and to pass her the trophy on that final sunday, it will hit me to the soul. >> anchor: good to see you. >> thank you. >> it has been 50 years since the first guinness book of world records was introduced. since then, it has been an institution, and a point of

pride for the institution. they are celebrating in london with the latest edition. >> it was in the early 1950s with a shooting party in ireland. guinness, and argument over which was the fastest european game? no one knew the answer, so he commissioned a new reference book, and here's the first edition from 1955. in the 60 years since, at this office in london, begin u guinns been the official book of the fastest and the biggest. there are surprising nuggets. mount everest is known as the world's highest mountain b. you the tallest mountain is on hawaii, which rises 10,000 meters from the sea bed. and it makes the difference. >> the widest possible
