So what exactly is overpopulation. It is defined by carrying capacity a slightly complicated concept which basically means the number of individuals on ecosystems resources like food water and species can sustain indefinitely but demographers have consistently got it wrong. There almost. Because we have. Natural resources. So were not quite sure what the odds carrying capacity is because the variables are constantly changing one things for sure its not the population element thats going to be the problem. Already in the developed world the population has largely stabilized 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 dont look like it yet. Its deception the crowded and there. Is planners havent really taken into account population growth and anyway and then theres the 2nd point which is actually kind of the 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 contacts. Globally across cities within cities they are highly highly in the. Ok so lets then look at how we are consuming resources and that equation. Every our Research Shows look at the earths annual resource budget and calculate at what point he was that. If we look at this by country the differences are startling many nations in the middle east and west exhaust the budget in the 1st quarter while a few countries like india dont overshoot yet. They reckon 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 shouldnt we have done me looking at who is consuming and how much instead of simply counting the number of people. One. The 1st studies to compare global emissions involved over 200 diverse researchers and policymakers the result called project drawdown publish a definitive list on reducing our impact we did a very complex models you know we didnt know what they would be i had a strong hunch of what the top 10 would be and i was clearly wrong all the rest of us were wrong number one is refrigerant management yes you have that right the way we keep things cool is one of our worst offenses against the planet our air conditioners and referee 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. A lot of big one on the list is something we can all individually do something about. Almost a 3rd of all missions go to the food system to waste not possible. No one can really deny that the human population has an impact on the environment but right now wealthier countries emmetts so much carbon that even. In the global south one significantly impact the rate of Climate Change but also learning consumption sounds weird easier than deciding whether that many people should or shouldnt exist to say that to many people is sort of. Kindness to a person. Which person thinks or to know. Its time to change the narrative away from the easy to blame visual problem of 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. 2 poles of the worlds population lives in urban areas by 2050 according to the un expected to only get worse part of the world work in changing the infrastructure in germany capital berlin and developing projects for the mission the city and smart a. 1000000 dollar limit livable is best achieved with the help of people who live here via when hes in 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. Voters take a left gets around by bike. The thrill moved in and out. Loud and i dont want to live in a noisy polluted concrete jungle without i want to live in a city where people chat on the pavements and dont have to shout at one another over the roar of porches was a gas deporter. The platform fix my berlin was set up a year ago for the city cycling. It allows users to see for example where theres a new bypass or where a new one is planned it already has a 50. 100 users the idea is to put pressure on urban planning authorities if. Theyre planning a new bicycle boulevard or new bike racks the public can say whether they approve of the plans. So you can see whats 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 its office is in city lab or land a shared work space for people developing projects and ideas to make berlin greener and smarter. 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 the city more livable and. Population increases by about 20000 a year according to forecast 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 lapper land are seeking to answer with the help of Data Collected by traffic cameras. Lets take a busy balanced each as an example a street you think would be quite dangerous for cyclists. Would look at that your checked aries 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 berlins streets when the pandemic hit the city created a number of pop up cycling paths. But the fix my berlin team say theres still a lot of work to be done. And im sure that. Compared to other cities the mayor and the City Government arent very invested in cycling policy. In paris and london its a political priority at the water. And. Perhaps not yet but the visionaries at city lab are working hard to get berlin up to speed. That so many people are rising around the world to make a positive impact on the earth is a hot fact i hope you will examine your impact however big or small it right to was if you have any questions or thoughts about it going to. Well see you again next week until then good bye. Moving. The movement. You know that 77 percent of. Our youngest and 6 oclock. Thats me and me and you.
