biosphere 2.anist linda leigh was one of the eight who spent two years sealed inside a giant greenhouse. i was drawn to a group of people who had a vision to build a biosphere and it was that magnetic pull of having a vision, working towards it no matter what, that pulled me into it. at dawn tomorrow, a unique experiment begins. biosphere 2, the prototype space colony in arizona, is being sealed up, with four men and four women inside. it is an attempt to discover whether human beings can design a completely artificial world and whether they can live in it. biosphere 2 was built to be a completely separate world from biosphere 1, which is the earth, and in making its separate, we have a glass covering that means that all of the air inside of the biosphere is created by what is inside of it. so we had a couple of acres to grow all of our own food, we had to grow our own oxygen. we had to get along with each other, do the research, keep the mechanical systems going. when we finally got in, closed th

it's based on the experience of biosphere, biosphere 2 in arizona in the early 90s. you have really drawn a picture that is similar to, but, in so many ways, different from the real thing. - well, thank you. when the biosphere 2 experiment first happened in 91 through 93 northeast of tucson, i was fascinated by this. like most of the public, i clipped out all the articles. i thought, this is right up my alley because as you know, evan, i often write about ecological concerns. for those who don't know, a friendly texas billionaire-- - ed bass. - ed bass put up the money to create a new world. 3.15 acres, 3800 species of plants and insects, four men, four women, to be sealed inside for two years. this was the first closure of a projected 50 so this would go on for 100 years. the whole point is, nasa is still after this, by the way, is could we create another biosphere, other than the one we live in here, in the event that this one should collapse, which it sure looks like it's happening right now-- - honestly, it's about 50/50 isn't it? - exactly, or a mars colony, or

its own two the biosphere center in it i learn more about you nest goals network of biosphere reservesthere are more than six hundred fifty of them worldwide including this way be an elf. the head of the center tells me what's so special about three jin foma how did she swabian alper in this title of biosphere. we have a bouquet of fantastic themes there are large numbers of castles and palaces here lots of caves you can explore it's wonderful who hold my views when i hear biosphere reserve and the first thing i think of is conservation and on sport nature how do towns and car traffic fit in with that. in the offended me angel miles fair reserves are about protecting nature but also about people and establishing harmony between humans and nature the biosphere areas protect cultivated landscapes the juniper heats woodlands in orchard meadows to protect them by using them. we have to keep using these landscapes in order to preserve them for people nature and of course for tourism with. many tourists who come here all fours lovers the swabian elp is perfect for a holiday on horseback ther

unesco declared it a biosphere reserve in 2012.lot has changed since then, especially when it comes to attitudes about plastic waste. >> leve, leve. take it easy, as they say in principe. but not when it comes to environmental protection. 24-year-old cileine fernandes has a long hot day ahead of her. >> good morning. i've come for the plastic bottles. it's exchange day today. so how's it going, is everything ready? >> a lot of bottles have piled up in her grandmother's backyard. every couple of months, it's time to get rid of them. >> aren't there any more lying around? we've got to collect the whole lot. >> the bottles are valuable because they can be exchanged. >> everybody wants the biosphere bottles. it really motivates the kids more than anyone else. they collect as many as they can, so you hardly see any lying in the streets now. >> everyone wants to trade in their bottles. the lucky ones can hop on board for a ride. the most popular means of getting around here anyway. >> it's busy at the collection site and stays that way t

the script on the biosphere and there's a big one there are other examples as well such as fecal transplants which are graphs of faces from one person to another. and so on this is a rather disgusting job here as this is but it helps to fight against certain infectious diseases which can be cured with antibiotics. transplantation is effective in ninety percent of cases and then and discover how we can also expand this research with use of such knowledge might enable doctors to find the right donor for an intestinal transplant the one containing the right enteral type which could increase the transplant success rate and is it a smoke to steam folks a lot it's a study done. the idea of transferring intestinal microbiota could revolutionize medicine. worldwide many teams are working on new solutions to treat patients with metabolic diseases such as diabetes and obesity in particular. nutritional specialist dr karim climb all coordinates a major event funded program investigating the role of gut microbes in cardio metabolic diseases here in her medical unit in paris her team is undertaking impor

unlike the biosphere 2 expeerment, where some were not on speaking terms by the end, they said this group said earlier that they think they're going to be friend forever. so, pleased to see that. >> crew members were able to communicate with loved ones during the study. but it was subject to a 20 minute delay each way. that tea how long it takes for a signal from earth to mars. any time they ventured outside the dome. the crew put on space suits. the harsh landscape. 8200 feet up is similar to what astronauts will encounter on the martian surface. >> send humans out. important for the future of the species. think really important to, to get off of earth. look back at the geological record. it is just full of mass extinctions. >> the next mission begins in january. and they're still taking applications, if you're interested. well that's the "overnight news" for this tuesday. for some of you, the news continues. for others check back with us later for the morning news. and, of course, cbs this morning. from the broadcast center in new york. >> it's tuesday, september 19th, 2017. this is the

and we try to circulate information and tactics and knowledge, so that the whole social movement biosphere around the world can be as intelligence and as equipped as every particular social movement. and finally, we represent a vision of social change. so, we are not utopians but we believe that it is important to keep a vision of the world you want to live in, in front of you, like a star on the horizon that you can navigate by. right? so, what connects, what connects all of the different struggles we report on and all the different activities we're involved in, is this vision that we call anarchism, we mean opposition to all forms of oppression, a system of values, you could say, like ethics, an idea of what it is that makes life most fulfill, that can connect people, that can make our connections worthwhile. and when i say opposition, all forms of oppression, all of the mechanisms that impose differences in power between people, that make it more difficult for people to carry out self-determination to live their lives on their own terms and i mean white supremacy issue mean pate -- patr

how can we characterize the biodiversity of life in the universe when we have one biosphere. so we have traditional ideas, but we don't really know. how do we address your question. one thing we do is we think about, and it causes us to think deeply about what life is and how it interacts with the planet. and we surmise even if life is very different from our kind of life, it's got to be sewer acting with its planet -- interacting with its planet in some ways. life multipie -- multiplies, so we talk about looking for dis- equilibrium, changes in a planet's atmosphere that don't seem to be caused by any non-biological process. there's some weird gas in that atmosphere that can't really be caused by volcanos or other things. certainly, if you were an alien look at earth, the first thing you would notice. all the other planets -- >> i think the simple answer is you look for signal, right? and that's what david's just talking about here. the signal from earth that there's life are only twofold that are really important. one is, you know, we've been broadcasting things into space

unlike the biosphere 2 experiments of the 1990s, this group seemed to get along. >> they said earliernk they're going to be friends forever so we're pleased to see that. >> crew members were able to communicate with loved ones during the study but it was subject to a 20-minute delay each way. that's about how long it takes for a signal to get from earth to mars. any time they ventured outside the dome, the crew put on mock space suits. the harsh volcanic landscape, about 8,200 feet up mona loa is similar to what humans would encounter on mars. >> we need to send humans outs because it's important for the species. if you look at the geological record, earth is full of mass extinctions. >> reporter: the next hiseas mission is scheduled to begin in january. the members of that crew, which is still being finalized, will also spent eight months inside the dome. nasa wants to send humans to an asteroid by 2025 and to mars some time in the 2030s. >> still can't believe that. it's amazing. >> it's incredible. >> wild. i think it's a while. >> the hawaii part doesn't -- >> once you get there,

we don't really know how to define life because we have one example of life, which is earth's biosphere. it is a weird thing scientifically to define and search for something that you have one example of. could you imagine you know trying to -- if you had one organism, and that's it shlg trying to characterize the biodiversity of life on earth. we couldn't do it. how can we characterize the biodiversity of life in the universe. we have these theories, probably needs water, needs carbon, we don't know. how do we address your question? one thing we do, it causes us to think about what life is and how it enter acts with a planet. we surmise even if life is very different from our kind of life it has to be interacting with its planet in some ways. life multiplies, uses chemicals and changes the chemical environment of its planet. we are looking about disequilibrium, changes in a planet's atmosphere that don't seem to be caused by any non-biological process. there is some weird gas in thatafter that can't be caused by volcanos or another things. certainly if you are an alien from aert lookin
