2:15 pm
or the apple app store, i'll give you access to all the latest news from around the world, as well as push notifications for any breaking off for this hour of next week. got doc film science of urban evolution. so stick around for that one more top the our way in blue cross. thanks very much for watching music. 50 years ago, the international gathering of peace and cooperation becomes the scene of a horrible tragedy. arab terrors, armed with sub machine guns, went to the headquarters of the israeli team and immediately killed one man. they're all gone. how i witnessed his experience to the terrible events,
2:16 pm
the long shadow of the 1970 to olympic massacre, start september 3rd on d. w. ah ah. busy busy in a lot of ways you can think of cities as. busy one of the largest unplanned experiments of all time. mm that these are places we call them extreme habitats. really, there are places where there is a lot of opportunity. and at the same time, there's also challenges as al cities. sprint, how well nature respond? well, plants and animals dwindle, or will they adapt to up in my life? and what kind of new interactions will we see in the city?
2:17 pm
in the historic french town up, i'll be biologist frederick on to keep an eye on his catfish. in 1983 fisherman released these eastern european fish into the river tom to day there at the top of the rivers food chain where he seduced this machine on the bus. this is the fascinating species because we know so little about them. there are many myths that people believe even that they eat dogs. they are many stories like this. yeah . yeah. could you still off? the biologist is interested in the behavior of the large fish that circled the reservoir basins on 5th on i to kentucky. but we work with fishermen to tag the fish and ha ha, they contacted us after observing very strange behavior in the fish here. the alvin
2:18 pm
dickens walked along. it caused it. you see, i'll meet the man my landscape of the city foster's new encounters between species . busy lip, your eas, latigion have never had to face predators from the water level gallant 8th. instead, they scan the sky for birds of prey. can you see the pigeons approached the water to bathe and drink? sometimes a bird misses the narrow strip of safe ground and touches down in open water. unless you're the catfish don't really see the pigeons unfit. but once they sense the birds movements in the water with their barble silly job, then they strike i should offer. ah, scientists observed the count fish's new hunting tactic for the 1st time in 2010.
2:19 pm
here in al me, pigeons are no longer safe on the water. the city is bringing together new predators and pray ah, for some catfish here, pigeons now account for up to 40 per cent of their prey. blue . they're suddenly this ecological interaction, which allows for evolution to start to improve the burt catching ability of the catfish and also to improve the escape ability of the pension. so you can expect that all these new interactions are also causing new evolutionary dynamics. dont', evolutionary biologist, minnow, she'll 1000 researches the adaptation of wildlife to the city. darwin's theory he
2:20 pm
believes, has gone up and ah, ebony pollution is evolutionary change. so really genetic change in wild animals and plants in cities. it's all about understanding how species will be able to survive in this very human dominated context cities, a homo sapiens, most extreme intervention in nature with concrete and steel. we create new landscapes and alter the face of the of. ready already most people live in cities rather than in the countryside. counties this influence evolution, the development of new species. what selection precious does the city create a summer evening in the dont' capital amsterdam,
2:21 pm
in the fall dell park in the center of the city biologist, men oh, shoot. how's him? uses a light trap to catch insects. oh, he's leading a citizen science project to explore urban nature. oh, for insects and for some smaller plans. the diversity today in cities seems to be higher than in intensively managed agriculture or areas. today, agricultural land is so intensively managed and every last bit of production of squeezed out of every square meter of surface area. there's no space for nature anymore in the countryside, and at the same time, cities get more, they get greener, people pay more attention to nature and to and to urban nature. so it's actually becoming a very rich environment with, with a higher by diversity than outside of the c o. m. we are rapidly
2:22 pm
losing bio diversity. both within and outside out it is for insect, the declines are particularly severe. ah, in the swiss alps, me as eric scientists, fully an ultimate has set up his light traps ever since humans began to light up the night. millions of nocturnal insects have been dying off every year. and it's all for a species like this, being attracted by light is problematic, because then it's confused the few short days it has a month to lags, come light pollution is one of the major trends demands scientists are even going, is found to describe it as an insect apocalypse. thank you. yes, i think the declines we are seeing now are already quite worried. off secret studies show a 60 to 80 percent decline and biomass hiv i sometimes even
2:23 pm
a nature reserves recovering that these are incredibly large numbers. slavish goals . it's all in, in my childhood i used to observe much like these so me, coleman. i would set up this trap next to my parents house and attract months actually quite large numbers them. but today i would probably not find many of them . often i, you know, she stopped the hit solemn daughter with a short movie, finished that for you live in them, but might in fact be capable of adapting to life in the perpetual night of our cities. florian ultimate wanted to find out his test, subject the spindle, ermine month whose caterpillars develop on the european spindle tree. now the thought i actually it was a coincidence. while i was working on my ph. d thesis. every day i walked through a park that had these european spindle bushes. and i noticed that with these caterpillars, these moths, which must have lived there for years or in a city park with permanent light pollution intended for smoked some east. i thought
2:24 pm
i could just collect them, raise them, and test how much the adult mots are attracted by light, bianca locked with in. formerly, with these experiments in 2006 altamont pioneered research into urban evolution, he released the moths in a darkened room. the next morning he counted how many had flown into the light tramp? it gave his yvonne, the results showed a difference. about 20 percent fewer urban lots had flown into the tramp halter of some state dish around what an aunt he looked. shar therapy brushed off among, i was very surprised, concluded that it was widely known that mots are attracted by light some more than others proceed about him. these differences have always been observed between different species. in the whole, i see in variations within a single species that we've never seen before or bought it. the experiment clearly demonstrated an hereditary adaptation to life in the city. direct proof of, of an evolution. for dont' biologist, men oh, shoot. how's him to findings confirm
2:25 pm
a larger picture in amsterdam, he and his group of citizens, scientists debate whether we might soon observe even more and greater adaptations of animals and plants to the city. ready we see that evolutionary processes are starting which will eventually or who eventually produce new theses that are specialized on living in the city. financial thompson. it's not if, but when every organism that lives in the city will show this urban evolution, these rapid changes in their behavior, in their physiology, in their appearances, to optimize their life in an urban environment. but won't ellamin said urban landscapes, prompt wildlife to adapt. evolutionary biologist,
2:26 pm
jason monkeys, south is an expert on animals found in the parks of new york. for years, he has been studying how rodents adapt to the city along with human immigrants. from europe, rats also voyage to the new world. today they roamed the city in subway tunnels, most native wrote in species, however, dom dan, trying to unlock crossing town. this distinction sparked the scientists interest. i used to be a tropical biologist, but then i moved to new york city for my 1st academic job. after graduate school and i decided i wanted to do some local work that would be interesting to the people of new york city and to my, myself. and i found out that there was a small mammals living in the centrally islands of worth and video. but that's interesting, nobody's really ever looked at these are they become a jagged different from mice outside the city or the end happening. and that's how it all started. central park opened in 18. 73. it still hosts animal species that
2:27 pm
lived here long before the city was built right now we're in the middle of central park. we're going to be traveling to the north end of the park where there's a very nice for, it's called the northwood. and there will be setting up traps, hopefully to capture white put in my one of the things that inspired me when i 1st started this work is if you look at new york city subway map, you see the subway lines. but then there are these large green shapes, rectangles and ovals, and so forth that are the, the parkland. and they put those on the map so you know where they are. but you also see that they are almost like a chain of islands that are scattered in the sea of concrete and roads and buildings. and, you know, 8 and a half 1000000 people. so in a sense, if it's a species like a mouse that can't leave the 4th cross neighborhoods and buildings and roads and make it to the other patch. it is essentially the same biologically as if they were
2:28 pm
on an island in terms of them not being able to move and spread their genes with the other patches. and these urban patches, once they become sufficiently isolated, operate like a mini galapagos and may be driving the evolution of many species that are, you know, stuck there. now, the evolutionary biologists investigating whether the white footed mice actually develop indistinct ways in each of the various palms would be a really nice spot for white, for the mice. they like to move next to log. so they're not completely out in the open. they might actually even be living inside this log where it's rotting or in holes underneath the log. so this is pretty much the ideal spot. this forest is encircled by the big apple. have the mice already adapted to this unique environment? what traits to they need to survive have no shortage of good trapping
2:29 pm
spots later i'll be going to one of our more suburban, almost rural sites for the larger, more intact forests, less urban ization. and i'll be setting out, you know, an equal number of traps. so the hope that we catch mice there as well. jason mankey south will search within the animals genetic codes for the malcolm of life in the big city. ah, i think what's been most interesting to me is thinking about how the things that we're all doing in our daily lives, where we put our garbage, what we're choosing to eat and what we generate as ways where we choose to live. how we choose to go to work or how to restaurant or something. all of these things we are doing are now influencing other species in a way that we're just starting to understand it. but it's not only
2:30 pm
animals that adapt to human intervention in the natural world. plans to the same in southern france, the yellow flowers crap. his sanctum is being studied by ologist pierre. only be a ship to keep you. so does the news. crevice, santa is a very common species in the mediterranean regions, a kind of mediterranean dandelion from the same family from here. and its essential advantage as a model is that it produces 2 types of seeds would read the large ones and small ones and dig also. the small wild flower produces both like to see with parachutes, allowing them to glide and heavy, a seeds that simply fall to the ground measurement of us. ooh, i'm interested in the process of adaptation to an urban environment. and in particular, what happens when a species 1st arrives in the city? so it is recently colonized certain areas of montpelier. in my comparison between rural and urban populations, i focus on the traits related to seeds,
2:31 pm
lee k. yet again, the idea of studying the adaptation of the plant to the city came to shift to almost by chance. when he came back from abroad, he noticed the inconspicuous flowers growing in the city. aid of japan demoya adie nija. i left montreal in the middle of a blizzard dodge. i took the plain for paris, l u m. then i took the bus to downtown montpelier, where it was sunny it with a clear blue sky is all of young also. and then i noticed there were crap as sunk to flowers everywhere, and those tiny urban patches. and suddenly it struck me that there was something to figure out here. redeem a lot, but i didn't yet know exactly what made lucy on tweak. because actually the crap is sank to thrives in rural areas and not in the asphalt deserts of the city. lead leno to ignore the predominant component in cities, especially in european cities, is concrete. its urine concrete exerts a powerful fragmenting force on the habitats of plants. supposing they have to survive in many by a tow basil feudal the put is
2:32 pm
a beat up. sometimes the cities constraints on a plans habitat can be extreme. how will evolution respond? house cement, vested of, i'm looking at how urban fragmentation will modify the dispersal traits of this species his best. i expect plants that produce more of the larger seeds will be more successful at reproduction in urban areas than they would be in the open country. oh, the heavier seeds are less likely to be swept on to the asphalt. and indeed, the biologists discovered the farm. all plants in the city produced the heavier seeds and thus better able to survive a difference of 15 percent. but what stands out most is the speed at this adaptation infected and we're sure the evolution we've seen has taken about 15 years. so this is extremely briefly. it was the 1st demonstration of such a rapid evolution of sci traits for plants. and this is due to the highly
2:33 pm
fragmented composition of the urban environment and mo, gilba it, did you talk about the exciting genetic changes occurring at such a rate of long being considered unlikely, even impossible by science or i think i would have been amazed by the fastness by which these changes take place. he was, it was sort of underestimating the power of natural selection himself. he said that you could never see any of these changes in progress. you cannot actually observed that. you can only deduce them from the fulfills from the patterns that you see in nature. you said that the illusion is too slow to see it happening in real time and effect that now today, especially in cities, we see these change is taking place under our eyes in the streets where we live right around us. i think darwin would have been thrilled. but what if man made
2:34 pm
pollutants substantially distort the biochemistry of organisms in the 1970s, the water new bedford harbor, the boston was severely polluted with p. c. b's. the u. s. environmental protection agency. wanted to know just how bad the pollution really was. the original focus was on what must be wrong with all the fish that live in that harbor because of the toxic chemicals. instead, we came here looking, trying to understand what must be right about those fish that could survive here. mm. so they've become a natural experiment for us to study how animals can adapt to toxic human made pollutants. just what we're looking for. let's get them into a net. bring them back to the lab. diane not, she had the environmental protection agency lab in narragansett,
2:35 pm
rhode island in that reading facility. the scientists want to unravel the mechanism that allows this population of kili fish species to survive in the p. c. b polluted water of new bedford harbor. so let's see if they left any eggs flora. they planned to compare eggs from the new bedford hob, a fish with those of a fish population from a clean a site. oh, let's start a test and see what they do when we expose them the chemical these killy fish species that cause all along the north american atlantic coast. the killy fish has been a favorite of biology literally for centuries at they are quite common. they are
2:36 pm
non migratory, so they reflect their local environment, and each population is unique in that it is genetically different. it is adapted to its local environment. so it gives us opportunity for lots of studies. the researchers need to observe the development of the fish embryos in the egg in order to understand, at which stages the environmental talks and disrupt the animals, biochemistry or not. ah, so we'll look at the rate at which the embryo is developed and certain features that we know that p. c. bees can disturb, like a proper development of the heart. evidence of proper development of the circulatory system and proper body side. mm. why these particular fish able to resist deadly in her mental talk sense?
2:37 pm
what are the factors that allow individual species to adapt to the city? all parallel developments taking place in cities wild white. at the university of toronto, mississauga, evolutionary biologist, mark johnson, pursues these questions. in a lot of ways, you can think of cities as one of the largest unplanned experiments of all time. the problem is, is there's very few organisms where you could study annotation to urban environments on a global scale and white clover is one of those very few organisms where you can actually do that. so now this then becomes the model to understand whether organisms in general can adapt to the convergent environmental changes. so she was cities throughout the world. research is across the globe by working together in this study, evolutionary biologist,
2:38 pm
stephan guyana. and his team are collecting the white clover in berlin. in cities, the plant face is a different habitat, temperature's a higher than in the suburbs, and the countryside was one have ottoman con is what you can expect is that as humans creates new environmental conditions, life will adopt. and to be able to show that on a global scale, that's a real scientific benefit. and that is why we're dedicating a free time to this project. fewer than filed them as they proceed from the countryside to the city center of berlin, ghana and his team collect specimens at 35 locations. this gives them a sufficiently broad range of data to compare with that of other global cit, is they fine to have final samples at the foot of the television tower spot. that's it all done in all we have a 168 cities right now and over $250.00 collaborators all working on the same
2:39 pm
project together. there's never been a collaborative project on evolutionary biology of this scale. and so this is the largest collaborative project in evolutionary biology ever. so is clover developing in the same way all over the world, into a kind of global citi. clover from the vast set of data. the research is hope to find an answer in the grounds of a research institute, north of new york geneticist, jason mankey south wants to catch white footed mice to compare that dna with that of those in the city. but it's not easy. ok, ah ah, so this is a trap that was opened, it didn't catch anything. obviously. that's a toad at that it was a map day for wildlife.
2:40 pm
ah, you're really surprised that almost every park was different from every other park . it's always to the point where you could take a mouse from one park, give it to our lab, and we could just look at a small segment of his genome and tell you where it's it came from. that's how much they had changed just randomly over time from being isolated. and that's when we started our current studies looking at, you know, over 20000 genes to see what genes and potentially what functions change when they adapt to living in, inside of new york city. ah, there's one 1st wait for the math of the day. with a new study, jason monkeys, south and east team, i've already caught more than $100.00 mice. and to analyze that genetic compositions, they try to take their samples as gently as possible, so as not to ha, the animals. mm hm. we take
2:41 pm
a jack sample in this case, we will be using this small tool. it's like a paper punched, but for tissue and we store that for genetic analysis. and we want to be able to tie that tissue sample to a location because that's important for understanding how they vary when they're in a more urban or less urban population. so now they're pretty m o, well this is a male. this young male are why don't we take the air punch and we'll start on the other one half isn't suitable for comprehensive genetic analysis. so the research is take a tissue sample from the ear. ah, yeah, he gets off to collecting the samples and some measurements of the scientists release the mice. genetic analysis can reveal the evolutionary
2:42 pm
trajectories of the mice. there we go. they point to a variety of physical and behavioral changes spreading among the animals. each of them unique to the challenges of each city park environment. so we're starting to fill in our gradient really nicely. ok, so here the my seattle today from the color center and you can see it's right in between highly urbanized new york city. and then all these sites we have up here and one out here. so central park seems to be our most distinct population. to date, it makes sense. yeah, yeah, most urban, probably the most isolated. so if you took a mouse from central park, some of its scenes will be different from mouth outside it in the countryside, in a big park some way. so for this one, particularly the food supply in central park and much of a human food waste might have triggered
2:43 pm
a genetic response in the city near central park. what we've learned so far is that one set of genes that are changing in the city have to do with metabolism. so these white food of mice are eating things and they have to digest them and assimilate the nutrients. and we know it's evolution because a heritable change in dna sequences. evolution central pock my seem to have genetic, it ought to their metabolism to better digest fast food in res, several like broader questions about what we are doing as a species. as we modify the earth habitat for our needs, how are we changing the future of other species? not only affecting them, but we're changing what they will become in the future. ah, narragansett. diane nazi and her team are investigating how the different fish embryos exposed to the toxic p. c. b 's have developed by going really well. so this is the study that's comparing scores
2:44 pm
creek and new bedford harbor experts to p c. b 126. so this one is the group that was treated with p cds and also from the clean site creek. and as you can see that you have had a pretty dramatic effect on the development, which is what we expect with these very toxic chemicals. yeah, and in my experience when i see this, this constellation of anomaly is absolutely lethal. there's no way that that an animal would even hatch, nevermind, survive after hatching. if the heart is not functional and the blood is essentially not circulating around the body. so let's take a look at that biochemical end point to see if they are also responsive at the biochemical level. using a special contrast agent, the scientists can trace enzyme activity in the on hatched fash.
2:45 pm
so you can see that the, the substrate is flora thing in the bladder showing that this enzyme system is working and we're, we're getting the expected metabolites of water. that's a very dramatic demonstration of enzyme activity in a living organism. the active enzymes in the fish embryo reveal how the organism tries to break down the thompson, but perishes in the process. then the team observes how the offspring of the fish from new bedford harbour have developed. ok, so these are fish from new bedford harbor that were exposed to the same level of p c. b that we were just looking at. as you can see what this embryo doesn't seem to have any effect, the heart is still beating normally and healthy. and it's developed really well. now, looks like an embryo that's about ready to hatch. some of them actually already patch
2:46 pm
these fish should be dead poison by one of the most lethal environmental toxins. but life, it seems, has found away. one thing we know about this class of chemicals is that in all vertebrates cleaning people, the, it turns on a certain enzyme pathway. so normally responsive person, or in this case of fish, should have that enzyme system turned on. if they were exposed to p c b, the contrast enhanced image shows how the n times that normally respond to the toxin remain silent. so in this case, i see very little that's glowing brightly is a dramatic visual difference. that suggests that that enzyme system is broken in the new bedford fish. the killing fish from new bedford harbor have changed their
2:47 pm
metabolism. the poisoned can no longer hamden, but which genetic modifications lead to the fishes toxic resistance. that's why geneticist ma. com of the woods, whole oceanographic institute wants to find out, could this be a key to understanding how nature might resist human interference. ready in that of our tree, he uses the crisper cash method. it's an incredibly powerful way to modify the genetics of an experimental fish like this to ask questions about the roles of certain genes. and in fact, the roles of even single amino acids in the protein can be investigated with this chris per task to task their assumptions about the resistant kelly fish market and his team experiment with that profession. i want to find out exactly what are the changes in those genes and to be able to actually 0 in on the specific molecular changes that are responsible for the resistance. and to be able to recreate that in
2:48 pm
the laboratory, to actually prove that that's the mechanism of resistance. where inserting portions of dna taken from the resistant killing fish into embryos of that pro fish mine you all you good. which ones are the injecting a p. exxon to com and his colleague neil lulu are using the most up to date genetic engineering techniques. here we are interested to city a function of g known as a p. so we are trying to delete this gene in this particular species and then played to steady. what's the function of the weather that will alter that a system to p c. b. in with these experiments, scientists venturing deep into the source code of creation. the scientists believe this research could yield the secret of life's ability to adapt to the most extreme
2:49 pm
and conditions. and this knowledge could also help other creatures to adapt and survive in a rapidly changing world. ah, i think we will understand the extent to which we can extrapolate our knowledge from the killy fish system out beyond to other fish and even other vertebrates. so a broader understanding of the toxicology of pollutants and how that will impact the natural world. how we can understand what will be the most vulnerable species the max planck institute in potsdam, the research team processes the clover samples from berlin. they're going to find cyanide, clover plants that produce cyanide,
2:50 pm
a better protected against predators. bots are less able to tolerate cold. it's warmer in city centers. so this clover might be more common that this isn't a glass, is a qualitative test yet by isn't, i mean, we use it to indirectly detect a specific chain that generates the cyanide. this could might be a different office. know you look like they're both rural now an institute of g. yeah. they're both still role dyna and his team send their results and other clovers specimens to mark johnson in his toronto. lon. hey, how's it going? good. the, the how did that extractions of this year? yeah, so remind me this is berlin and buenos ari's. the team prepares the clover for gene sequencing, but the cyanide values taken by the team and germany show whether the clover has adapted to an up and existence already. okay,
2:51 pm
better did we get the data from berlin? yes, we did. okay. here it is so great. thank james. have you had a chance to look at the data from berlin? so we can understand how the environments changing from downtown berlin, through the suburbs and into the rural areas. got it. all right, so let's take a look at so berlin is one of the cities where we see why clover adapting to urban real gradients. yeah. nice. and so now we're at about 33 percent of cities where why clover adapts. yeah. but yeah, fair enough about that. okay, so then next i think what we're gonna have to do is figure out what are the drivers, the environmental drivers of this adaptation. so that's really cool. in berlin plans from the city center, a more likely to produce cyanide, as is the case in a 3rd of the cities surveyed so far an indication of parallel evolution.
2:52 pm
some of the preliminary insights are, are fascinating. that really looks like, regardless of where you are in the world, whether you're in europe, north america, japan, china, australia, new zealand. we see the ability for this humble white clover to dat, to these cities in the warmth of the city sinai producing clover stance a better chance of survival. oh, but to survive in the city in organisms must adapt to higher temperatures. what scientists, school, heat islands and cities, humans and their machinery creates a lot of heat. and we have a, a bubble of hot air in large fifties, in a city of more than a 1000000 people can be 78 degrees south celsius halter in the center of the city
2:53 pm
than outside of the city. with this men, oh shoot. carson believes now it also influences the evolution of the white lipped snail on their shells. coming many shades from brown to pale yellow. a single gene determines the color. so they could basically carry their genes on their back. the, the shell color, the herman, the internal temperature of the hail to somebody in the difference in temperature inside can be 2 degrees under the same conditions. and that could be just the difference between life or death on a hot summer day. and you know, it was 40 degrees in amsterdam a few weeks ago. it could be that some of these yellow snails survived, but many of the brown ones died because they got to help they overheated and they died. but well, the statistics support this hypothesis ah, so the plan is now to,
2:54 pm
to just add some data to the dataset. so let's go in order to collect and evaluate as many snails as possible throughout europe memo shield housing is helped by volunteers. you know, you don't have to go through the galapagos to study evolution or become a part paleontologist is happening everywhere all the time. it's a continuous, very normal biological process. the group only find the fuse nails but even empty. now shells can also provide data that photographed and added to the database with an app that anyone can install on their mobile phone. ah, if we're looking at the adaptations of urban animals and plans to the urban heat islands, which of course is happening has been happening more rapidly than global climate change. we can probably predict what's going to happen globally in response to
2:55 pm
climate change. openings ation and climate change poses a threat to all plant and animal species including the monarch butterfly which gather in millions in the forests of mexico. every october, they've completed a 5000 kilometer journey to their winter quarters and increasingly perilous odyssey to the linsey miles studies. the butterflies in toronto, monarch butterflies are these really great insect. unfortunately, right now they're in decline. the and the united states, they've experienced 80 percent population decline in this industrial area of toronto, monarch butterflies take a rest stop before flying home. they also take the opportunity to mate and reproduce. really vague caterpillar. this is an let the baby monarch. this one's probably
2:56 pm
a day or 2 away from going into its chrysalis and then becoming a monarch butterfly. it's really cool. one other species had the ability to switch to other food sources. monarch butterflies remain dependent on a single plot. oh, i got one. let's check it out. we found a monarch ah, the butterflies laid eggs on the milkweed that caterpillar's feet exclusively on these plants. and in many cities, the land on which milkweed can grow is disappearing. oh, unfortunately a lot of these cities are providing these barriers that just don't have the resources that they need. and so it would basically be if you're driving along the road and you don't have any fuel stations and you run out a gas, you're stuck there. not what's happening with these butterflies,
2:57 pm
not all species can adapt. as our cities continue to expand, accommodating wildlife might be crucial how we shape our cities in the future may prove decisive for the course of life honor. 5 diversity helps us with the food that we eat. it helps us with the air that we breathe. so if we continue along the path that we have many different populations, including human population, will start to cry. the urban evolution can help us design green cities in our winning way. humans become more urban, we have the potential to, you know, allow some faces to live in a city and adapt to our cities, but then put less pressure on the other habitat which will allow the species that can't survive in the city to continue to threaten the we're going to see more and
2:58 pm
more of the realization that we are part of nature and that's, it's actually probably going to help us survive the me ah, the ah, we love europe. we love diversity and anything unusual. no mountain is too high and no road is too long. in the search of the extraordinary we are the
