for the teachers british and. beethoven's knights. for the world starts to simmer down on t.w. . and there are nearly 2000000000 people on our planet and the impact. on the one hand on the fossil fuel wasn't the non-drinking engine and the resources with nicholas lea consume but on the other hand our efforts to reduce our carbon footprint and work with the environment can't be when they will examine closely

think back to what bad and good so that we can walk and informed decision about your choices how welcome to equal india and some that one way of tackling the problem of overconsumption and the subsequent resistant generally is for people to walk with me and bob where they live the people in our next story live in a remote region of india with extreme climatic conditions it's not easy to make a living and transporting a regular supply of food and other essential uses a lot of energy in their bid to help the environment in a small this is the scene of billy growing i'm not going wild betty a potential super for providing them with a new source of nutrition and. the. conditions are cool up here in the mountain desert of long haul speedy in the indian stay. that of him archer predation winter is approaching the area lies both

1000 meters above sea level and temperatures can drop well below freezing in winter . conditions here can be harsh and climate change is making things much harder 2 years ago heavy snow fell in september by being out a key part of the harvest farmer priem chanda's 84 years old he says life here used to be quite different. in the past the better circle was fairly predictable of the world no one time and there was no trouble with water so the only travelling from one village to another was a problem. people here are cut off from the outside world for 6 months every winter during that time they have to live off whatever they have produced in the summer if the harvest of potatoes peas or barley is poor the farmers can't sell as much so some people have started picking sea buckthorn

berries or jeremiah as they're known here on new york city where you. will know it's only been the tibetan medicine men that have used them or on local mall didn't put them in the mideast for video. or. we had no idea or knowledge about the various ourselves but they knew all this is called well we don't know anything about their medicine the properties or any of the uses. we just thought they were of by. you. once a remedy used to treat altitude sickness high blood pressure ulcers and bone conditions today sea buckthorn is considered a super food the berries are in high demand among india's urban middle class and they are plentiful up here making them an ideal source of extra income the shrub also plays

a key role in preserving the landscape. is more. in abundance across the malia's across and many other areas too much of produce make the environment here is very fragile and croon to soil erosion. helps to preserve it by stopping the soil from eroding which protects the wildlife and that's just one part of the story reason. why. if they're after you. within they're saying has spent 30 years studying sea booked on the 1st scientists in india to do so at a research center in lahore he's breeding new where right is that are more suitable for farming the idea is to increase the use of sea buckthorn and maximize its potential always go through the fruit and the leaves are extremely rich in vitamins amino acid fatty acid and polyphenols. nor the plant in the world possesses

such a rich composition of compounds pretty assured him the amount of vitamin c. present in c. but is 4 times what is present in the indian gooseberry for example. there are only . $3000.00 tonnes of c both on are sold every year in india and the scientists believes that the demand could double over the next 5 years many areas have yet to realize the shrub's economic potential. local solution. i'm sure c.r. is looking to change that with her start up top so working within the sing and supported by government institute she's developed and marketed a result of sea buckthorn products including food piri and fresh juice need to alleviate there's a you know marketing agency for taking these producers and at the same time products also into the market the specific industries where they fit in basically

so we plug in different at those and different going those existing technologies and make sure that good from the harvesting. in the time that the product reaches the customers or the businesses in the right place and it reaches in no particular order in hands do nope quality we basically so that is what the person make sure. the start of works closely with pharma producer organizations known as field one of them is led by 81 year old former teacher be deeper she he represents the interest of $150.00 small holders in marketing the berries the farmers have long since recognized the benefits of seebach tone. or is caught up with god we will remember many of them with the process involved. and we farmers hardly have to do much work with. we don't have to deal with it in a gated or give it man or you know and yet we're reaping the benefits of your

border there are. the farmers used to sell their berries to intermediaries for less than 20 rupees a kilo and even that price wasn't guaranteed now by selling them to the f.b.o. they get $4.00 times the price for their produce so each farmer earns an extra $40000.00 rupees per season in addition to one day get for their other crops this is the marked on flourishes in the cold desert landscape which covers more than 40 percent of him archer predation the shrub is hardy it can cope with drought and temperatures as low as minus $43.00 degrees celsius for the farmers it has the potential to become a cornerstone of their income and because the seabrook torn is also good for the ecosystem it's a definite win for the region. cotton grows not only in the hymn ali and clinton but also in many parts of central asia and even the arctic over millennia it's

spread all the way to the alps in central europe and the cost of the north and the baltic sea. see about corn is also farmed in germany but in the past 4 years there's usually undemanding plant has begun to struggle. see buckthorn is basically our life philosophy or company philosophy. this area fish last in the north of germany used to be covered in sea buckthorn the lemon of the no as locals call it but now families like punch better sounding. for over the past 5 or 6 years we've noticed that more and more sea buckthorn shrubs are dying at 1st there were just isolated cases maybe one or 5 shrubs but the last 2 to 3 years it's been really extreme. vast areas that were covered in

buckthorn are just dying off. it's not exactly clear what's killing the shrubs with its northern climate and favorable soil seebach fillin used to thrive in the area around that fixed city but that's changed function is working with researchers to find out what's happening to his plantations. the researcher checks the question is what the problems usually begin to affect the plant from inside many dry out. but why it's still a mystery. good to hear that those. that the weather will no doubt have had a massive impact in recent years. so also obviously. at the moment it doesn't look like we're dealing with any kind of new previously unknown pathogen or disease . it seems to be a complex of different factors all working together. samples

of c. back thrown from all over germany are being examined for possible causes the german federal research center for cultivated plants is running tests to try to save the plant our hypothesis is they are me how were major role of fungi in this disease complex sundog it's quite likely that we are climate as an additional influence but there are certainly other factors that need to be investigated like forums or the effect of other plans like cultural practices. the harvest ended in september previous they function better collected around $80.00 to $90.00 tons of berries this year he got only 110th of his normal harvest. only

this freezer is usually filled with contain is. all they are spreading is kind on the freezer could be fuller given the time of year. but i'm not thinking about it too much at the moment for now we'll just process the berries that we haven't turned them into a good product so when once we run out we'll have to see where we go from there. looking to see bucks on berries have a long history in the face last germany's 1st ever plantation was here the berries are tot fruity and have a strong flavor and soon became popular in germany and their powerhouse of vitamin c c bucks on oil is used in a wide range of food and beauty products and nutritional supplements my favorite is the juice it's the most versatile product. what's also nice is honey with sea buckthorn and sea buckthorn chili mustard it's perfect to save the local

plantations researchers want to do an experiment they will plant 8 different varieties of sea buckthorn here most of them from the elves and then study how they cope with the local ecosystem. will be investigating whether these other varieties develop the same kinds of problems we see in the local shrubs. it may be that some of these other varieties are more robust and better suited to cultivation here in northern germany over the long term. for farm is the experiments office the hope that they'll be able to continue their production or that a solution will be found to restore ailing plantations part of that might involve new farming practices or organic supplements to bring the nordic lemon back to life . now when we begin to talk about the impact on the planet population is one of the factors. it's being blamed for global warming default

a station shortage of resources among many. in india for example has the world's 2nd largest population after china. but is there another way to examine this problem just looking. let's find out. in the time you watch this almost a 1200 people have been added to our population. breathing the same oxygen sharing the same space and creating more and more greenhouse gases . is about the population are back we need to address much more aggressively the population part of the equation if we keep norine exponential population rise nature reduce your population for us is this the whole story. about nature growth this. is just too

trippy. how many is really too many and what does the also have to do with frozen food. let's start at the very beginning when multi-fuel around meant security in an insecure show on the indian subcontinent for example china get the full also 1st suggested that widows quickly find new husbands find during the month the increase in population was celebrated as it meant more people could work on a farm and produce more food for the roman emperors were no different in some cases passing laws to promote early marriage and frequent childbirth so that armies could stay up to strength. setting up new colonies until the number of people started becoming a visible problem. in the 18th century british economists

started ringing alarm bells ok ancient history. in more modern times the feel exploded with the publication of a book called the population bomb. an american biologist one the western world of the conditions he had seen in new delhi. blamed for everything from. resource management to destroying the environment. some countries. and political. control. china became the poster child and its one child. gender imbalance and like other control. it was eventually. enemy had been identified as. so what exactly is overpopulation. it is defined by carrying capacity

a slightly complicated concept which basically means the number of individuals in ecosystems resources like food water and species can sustain indefinitely but demographers have consistently go to. their almost. because. natural resources. so we're not quite sure what the odds carrying capacity is because the variables are constantly changing one thing's for sure it's not the population element that's going to be the problem. already in the. i love towards the population has largely stabilized our begun to decline and the developing world is on track to follow education and access to contraception are driving the numbers down even if cities

don't look like it yet. its deception of the city's local crowd. is planners haven't really taken into account the population growth and anyway and then there's the 2nd point which is actually the kind of bigger impacts on the environment and a link to consumption. could say. as seen their own the world consumption unlike population is on an exponential rise. if we look at the levels of consumption across different contexts. globally across cities within cities they are highly highly of me. ok so let's then look at how we are consuming resources and that equation. every research just look at the annual resource budget and calculate at what point we will use it. if we look at this by

country the differences are startling many nations in the middle east and west exhausted budget in the 1st quarter while a few countries like india don't overshoot yet. with. india. and correspondingly how much carbon dioxide we entered on the world is different to in 2018 and indian family of 4 had a carbon footprint of less than 8 tons an american family of 4 in the same year came in at almost 70. so shouldn't we have done me looking at who is consuming and how much. instead of simply counting the number of people. one of the 1st studies to compare global emissions involved over 200 diverse

research shows and policymakers the result called project draw down published a definitive list on reducing our impact with is very complex models you know we didn't know what they would be i had a strong hunch of what the top 10 would be and i was completely wrong all the rest of us were wrong lever one is refrigerant match yes you have that right the way we keep things cool is one of our worst offenses against the planet our air conditioners and record today is still largely emmet greenhouse gases much stronger than carbon dioxide when cooling like transporting frozen goods. the project estimates that changing to more efficient cooling could save 5 times more emissions than if all cars became electric. the big one on the list is something we can all individually do something about. is huge it's.

almost a 3rd of all missions go to the food system to waste nothing. no one can really deny that the human population has an impact on the environment but right now wealthier countries emmett's so much carbon that even adding 3 or 4000000000 people in the global south won't significantly impact the rate of climate change but also lowering consumption sounds weird easier than deciding whether that many people should or shouldn't exist to say there's too many people is sort of. kindness to a person like which person thinks or to know. it's time to change the narrative away from the easy to blame visual problem. population to the more hidden and dangerous concerns of waste and overconsumption. we try to answer the biggest questions concerning climate change today.

in metropolis and around the world traffic is one of the major causes. of the world's population to live in urban areas by 2050 according to the un is expected to only get worse if you are part of the world work changes to their infrastructure in joni's capital berlin and developing projects in the city greener and smarter. milliman livable is best achieved with the help of people who live here via where using new technology to contribute to a better understanding of traffic. i would like to see the city authorities and the general public taking care of the trees in the.

city. the streets of berlin are increasingly busy with cars cyclists pedestrians. take the left gets around by bike. if released in are not. allowed and i don't want to live in a noisy polluted concrete jungle about i want to live in a city where people chatting on the pavements apartment don't have to shout at one another over the roar of porches was a pass to porter. the platform fix my berlin was set up a year ago for. the city cycling community it allows users to see for example where there's a new bypass or where a new one is planned it already has a 1500 users the idea is to put pressure on urban planning authorities.

already said planning a new bicycle boulevard or new bike racks the public can say whether they approve of the plans. so you can see what's possible what the public sees as a priority and what it sees as less urgent and where there is less demand. 8 people now work for the startup it's office is in city lab or land a shared work space for people developing projects and ideas to make berlin greener and smarter. the city like this in a city lab is a public innovation lab coat run biotechnology foundation and the berlin state we focus on the future of berlin as a digital city and we develop a range of products designed to make this city more livable. for lent population increases by about 20000 a year according to forecasts the city will be home to some 4000000 people by 2030

. how can traffic be reduced how can traffic flow be diverted to reduce congestion and pollution. these are questions that a group of scientists also based in city lab for them are seeking to answer with the help of data collected by traffic cameras. let's take a busy balin street as an example a street you think would be quite dangerous for cyclists. would look at that you check terry's see if they often need to overtake trucks and buses say and see if that could be quite high risk of. their findings could be used by urban planners to redesign busy cross roads for example. traffic patterns are constantly in flux recent months have seen a 25 percent rise in cyclists on berlin's streets when the pandemic hit the city created a number of pop up cycling paths. but the fits my berlin chain say there's still

a lot of work to be done. to understand the new you know. compared to other cities the mayor and the city government aren't very invested in cycling policy. in paris and london it's a political priority at the water. of south korea and. perhaps not yet but the visionaries at city lab are working hard to get berlin up to speed. that so many people around the world can make a positive impact on the earth in the ha fact i hope you will examine your back however big or small right to oz if you have any questions or thoughts about going . we'll see you again next week until then good bye.
