Supporters say that greater freedom for companies creates more trade. And as result more jobs and increased wealth. Critics believe the only ones to really benefit our Large CompaniesEmployment Rights they say will be gradually eroded. 1994 was the start of nafta the aim was to create jobs and boost the economies of mexico canada and the u. S. But in reality it led to the loss of 850,000 jobs in the u. S. In mexican agriculture that figure was as high as 2 million. We start in the u. S. Detroit, one time auto city. Here you can learn a lot abot. Bob bowen work in the car industry his whole life for ford and he also suffered the effects of nafta. Every few weeks, bob shows his grandson billy how hes getting on with his retirement project. A Ford Thunderbird from 1957 in its original colors. It is a real eyecatcher. He and his former coworker greg are going to show us what is left of the automaking industry in ypsilanti, close to detroit. Since the nafta agreement was signed over 20 years ago, their town has lost half of its Auto Industry jobs. The detroit region has bled hundreds of thousands in total. It is part of americas Old Industrial heartland, the rust belt. Behind the fans, theres not much left of the company that once supplied ford and General Motors with parts. Bob bowen when i first started working here it was a factory pouring iron. They could lower the unit costs to stay in so they started moving to the south and then even in the south the wages became too high and with after they started moving across the border. And then it got so that even the people of mexico couldnt compete. They were sending it everywhere. So that was the advantage of nafta. The lower wages. At some point bob bowen decided he had to take action. He swapped the Conveyor Belt for the works council. But of course he couldnt stop the decline of ypsilanti. His grandson does still have a job in the auto supply industry. Here is 18 an hour, his wages havent gone up for years. He is concerned about the stagnation of pain levels in the u. S. Bluecollar sector. Billy when i make now is what my granddaddy made in the 70s. It is hard to do that now with inflation. The cost of living we have, increasing taxes. Our union dues went up this year. It is harder to do. One result of nafta. The relocation of work from here to mexico. Bob i really thought nafta would help us. I didnt realize there was no labor protection, no way of making sure that things were fair. The whole advantage of corporations moving their was just screwing the workers greg the people that have control are very greedy. Money rules their decisions. People like us, the working people are collateral damage. Nafta and its repercussions have been widely studied. The trade expert has become of surfers critic of the plant teaching agreement between the u. S. And europe. Lori we have had 20 years of living with nafta and the thing i would say to our friends in europe is, dont try it. We have seen everything come true that the critics predicted that much worse. We travel on to mexico. The jobs that disappeared into troy and elsewhere came here. To acquire as, right across the u. S. Border. Where hundreds of factories have sprung up out of the ground. This is where basic components are manufactured for u. S. Industry and then sent back over the border. It is cheaper for the Companies Involved and provides work in mexico. Nicholas rojas is employed in the auto supply industry here. He cant work at the moment because of a workplace accident. When the cotton growing industry collapse in his home village, he came here. Now he is one of the hundreds of thousands of lowpaid workers in the city. Since nafta came into force,he city has grown at an explosive rate. Crime rates have also spiraled. Juarez has become the most violent place on earth so murder rates are no longer as high as the once were. Rojas shows us the factories. We drive past. It is not wise to stop here. The drug cartels have their tentacles everywhere. Nicholas behind me they make airbags for various Companies Just like i do. For harley davidson, chrysler, as well as honda and many other foreign companies. And this is where i work. It is not clear who is really behind some of the factories. But they all pay lower wages in this factory iron 97 pesos as a foreman. Thats about six euros a day. Some factories pay even less. Nicholas has to work three days to earn what u. S. Worker earns in an hour. Palin was are not sufficient in either country. Nicholas we have work yes but the pay is not enough. It is pitiful. He is divorced and he lives with his mother. His wife left him and took their children with her. His injured shoulder and the split of have hit him hard. He says that the nafta Free Trade Agreement hasnt brought him happiness. That feeling is shared by hundreds of thousands of other people in northern mexico. It is work, but under what conditions. Nicholas it is really not easy. It hasnt had any benefits for us. The government told us it would be good. But we are paying a high price. The poor working conditions are destroying our lives. We have the highest divorce rate here at the border. The fact is the u. S. Firms have relocated hundreds of thousands of jobs to mexico. And mexicos lowwage economy has also put pay levels in the United States under considerable pressure. Free trade increases competition, between workers as well as companies. Thats what critics also fair with the planned agreement between the usa and europe, tti p. The streets of asia are unimaginable without them. In other regions they are known as tuktuks. They are in important form of transport as well as safeguarding the futures of millions of families. Up until now though it is mainly been man behind the wheel. Parking bb smokes in public. That is very unusual for a woman in pakistan. She is an anomaly in lahore. She is one of the first in the city of 7 million to drive a rick sharga. Men are curious. Wherever she stops, she draws a crowd, even if she is simply asking for directions. How i get there . Straight ahead and you get to one on the road. Her fellow driver smiles and helps her, but he does not approve of her being behind the wheel. Many men here think that women should not be out in public. We dont like it at all. Women should stay at home, where they are safe. The problem is tshe is driving a rickshaw. She can work at home. But women can barely make ends meet sewing clothes. Whereas she can make a rickshaw. She is not willing to bow to convention or social pressure when it comes to providing for her family. I think men are not just uneducated, theres actually something wrong with them. They help old women. But not here. She has to look after her daughter and three granddaughters. They live together in a small tworoom apartment. In pakistan the husband and father is usually the family breadwinner. But her husband died and she did not want to remarry. After the death of my husband my two daughters supported me. They sowed clothing and work in the beauty parlor. But still there was never enough money to pay the rent and the bills. Then one of my daughters at her husband died. Their three children live with me. So she has to feed a family of five. A neighbor comes to visit. She supports her and her defiance of traditional gender roles. I work really hard. You see. She is now getting support from a new organization that trains women as drivers and makes special pink painted rickshaws. Women drivers for women passengers. The instructor might be a man that only women are allowed to travel in these vehicles. The pink rickshaw project helps the drivers deal with bureaucracy. Her instructor a companys her to get the vehicle registered. A group of men stand and stare. I am really excited. I granddaughters keep calling. Luckily she doesnt have to face the noisy bureaucrats alone. At least five officials examine the rickshaw. They take photos for the authorities. The registration has been completed. She sets off for the first time. It does not take long before she finds a passenger. A male driver wants the business to, but she got there first. The pink rickshaw project also helped her get a proper driving license. If it catches on, she could earn a good living and provide many women as valuable service. Women dont feel safe riding with strange men. I am out and about a lot, and feel much better with a woman driver. It would be great if lots of women started to drive rickshaws. It would make life easier for working women like me. She is moved. She has met with so much support, women in pakistan need to stick together. In our global ideas series, we had to brazil. More and more people are moving to cities. Because they all need a place to live, there is tons of Building Work going on. Which has consequences for nature. In the state of rio de janeiro. A town with a population of just under a million. Our reporter at a city planner went to look at the ramifications of unbridled growth. Three years ago a flood wave destroyed 270 houses here. Two people were left dead and 60 injured. The scale of the disaster became apparent the day after. Looking at pictures back then is still hard to bear. Her family managed to escape in time. But they have lost everything. This used to be my house. The water gushed in here through the window. We heard this adult side and immediately went to look. The flood wave had already washed away everything up front. We had no time at all. We just had to run. The houses were built right next to the river, even though it often rains heavily here. The trained architect blames poor planning in the past. He picks up the urban planning department. He takes us to the center of town. The city borders rio de janeiro. Almost a Million People live in this town, many of them commuters. In the last few decades the city has grown exponentially. The lack of urban planning a past demented buildings in the city were constructed incredibly close together. No green spaces were left. Everything was built over. The disaster that took place years ago has led to a rethink. He points out to us the coastal strip just beyond the city. He tells us this is the first time people have recorded how nature benefits the city and its people. A study was funded by the German International climate protection initiative. Thanks to this research, it is now easier to explain why certain Construction Projects cannot be given planning permission. Ecosystems and Natural Habitats have to be given priority. Everyone in the Municipal Authority is playing their part. We now have an instrument to shape urban planning. Development is now prohibited in the mangrove forests on the outskirts of town. They are just a few kilometers from the city center and they act as a flood barrier. He shows us around this sensitive ecosystem. Nature is really impressive. Especially here in the mangrove swamps. It is so powerful. The power becomes apparent on and tides. The creatures living in the mud become more visible. The crabs provide a livelihood for hundreds of families here. But the fisherman tell us that their halls are shrinking. Our guide tells us that not long ago he also used to catch oysters and salmon in these waters. Look how dirty it is here. All this rubbish floating around. The mangroves are the only things helping to combat pollution for us fisherman. The trees filter toxins from the water and then die off. If you want for them, we would really have a huge problem. Decreasing pollution is having a detrimental impact on the environment and biodiversity in is a development that is also a cause of concern for the city planner. In the future the citys existence will depend on the mangrove forests. We know that Climate Change is coming and the mangroves are our bulwark against rising sea levels. The town is located in a hollow. Even now there is a danger of flooding. The second Natural Environment of the City Planners now regarded as sacred is situated to the north of the city, the Atlantic Forest. More than 20,000 species of plants and more than 2000 animal species live here. It is our next stop and the director of the nature reserve gisele maderos joint us on our trip. The Atlantic Forest used to cover up large swaps to brazil. Only 7 of the original forests has survived. People pose the biggest threat to the forest. We have to communicate better than the financial benefits of blogging pale in comparison with those of having it intact forest. This is where the citys Drinking Water comes from. The rainforest also helps cool the entire region. It also provides another valuable service that explains it status in marco pierre as master lands. When it rains hard the rainforest retains a large volume of water and releases it into the city more gradually. It absorbs a lot of water and slows down the outflow. The rainforest has become a lifesaver for the citys inhabitants. Without it the flood wave would have been a lot more destructive three years ago. Increasingly areas close to the river are being left undeveloped, so they can act as a floodplain. We have moved on from the phase where we were concerned with building as possible without a second thought. Now we constructed building, we also coupled with a green space. No one benefits if houses are squeezed in that reach other and people are piled on top of each other. The quality of life suffers and it can cause disasters, like you did here. We want to create the city in which nature is a firm fixture. Hopefully the city respect its Natural Resources more in the future. It can only be in the best interests of the People Living here. 16 years since the start of the millennium.
