A large city like bali is finding you know way to be used to produce its own food and remain sustainable and why an architect from india is being called an eco pioneer. The. First lets talk about one of my favorite subjects for many futurist predict the beers not ready father and we have robot farmers harvesting studio closer to our homes or 3 d. Printers creating a perfectly suited cross off without emitting Greenhouse Gases but the food we eat today has a massive Carbon Footprint i went to meet 3 Game Changers in the city of bullion who are trying to find clean out in clean a solutions to help mitigate the problems in our food supply teams right now you know. 3. 5000000 inhabitants is not a big city considering indian standards but there are still lots of people to feed in the german capital i went. We explore how sustainable bully got in its Food Production. The ancient asterix of the chinese they did many millennia ago now a budding company is using the technology of aquaponics to feed the citys residents in the center of bullion a former malt factory this farm is producing food for billions its a combination of thrilling fish and green vegetables. Nicholas lescott and a colleague set it up 4 years ago the Carbon Footprint of traditional Food Production is very massive how is this aquaponics the solution to help solve this problem well aquaponics as a as a way to produce very resource efficiently food fish and vegetables of highest quality and if you do that within an urban environment of course you have very short transportation mileage you have very short cooling chain chains and an overall better c o 2 benefit than our reference farm here in berlin we produce about 400000. 00 pots of base loads per year and we can produce roughly 30 tonnes of fish and this is just a surface area of one 1800. 00 square metres if you could break down for me one of the 3 environmental benefits of using aquaponics well its the Carbon Footprint its the water footprint its the feed footprint and its the ocean footprint actually for what you think is the future of this technology in general i think as humans we have to produce food in systems like this where you take a very small footprint to produce large amounts of food with less resources this is a feat for a vegetarian like me im on my way to find out where i can find some lunch as fresh as this many places in berlin advertise the freshness of their products but its impossible to read good bank in this regard. At this restaurant the leads do come from the field instead you can watch a green screw right behind the bottle inside all glass by. Since im a can you tell me how the idea for good vacuum about you wanted to have a new form of astronomy fast casual astronomy in german is still very tradition all your work a lot of that convenience and so we decided to start just front that has the most visible history a 2nd see worth of farming to be a part of our work where we say ok you can have really high quality food with still affordable and fair products but with super fresh ingredients what would you say ever challenges to Something Like this in the beginning it was very difficult to sell the idea to the gas it was not really considered being who you are actually based and i remember when in farming fold the machines here were the Farming Models we had many guests that thought were old and not restaurant but now after 3 years of course people know what they get food here and that we grow on for. Any kind of consumption is a big impact on our end but i dont regard in the production of the transportation and even the compost to waste as one of the biggest problems in our Society Today but often what happens is when groceries are expiring be that theyre thrown into the bins but bullion has a very interesting way to tackle this problem this seems to be a Grocery Store like any other but the goods the selling i believe to be cool concord produced or expired food good stuff going to the trash bin elsewhere however theres still good to eat raw file film is the founder behind this unusual shop small flock suchness is operating in 4 different locations in berlin and in my shop this is such a simple yet you know its a fantastic concept can you tell us how it came about you have for me already when i was a young child felt it was a lot of injustice that we have hundreds of 1000000 people also children starving in the same time were throwing away food thats love possible any more than via. Believe but also ethically thats not correct as well where i wanted to do something to make this world a better place and thats why i started so close what does the future look like for so this and put a concept like our mission is was surplus to create awareness in the heads of the people because 50 percent of the food waste in germany and most other countries in europe is happening at home so we want to give the people again trust for their own census and our goal is right now we are throwing away one 3rd of all food in the world and the next 10 years we as a humanity appreciate food again more and use the food which we have instead of always producing more and more food which we throw away to come rough i felt hes creating a franchise to steve and.

In rural areas birds are natures pest control every year they eliminate about a half a 1000000000 tons of plant eating insects. And many help pollinate and disperse the seeds of plants scavengers such as vultures remove animal carcasses. In the city however birds must adapt to a new environment they dont build their nests on trees instead they build them on structures such as electricity poles or apartment buildings. They eat discarded food cities lack the large numbers of insects and worms they would otherwise feed on. Thats why some experts believe that birds that live in cities age more quickly and have a lower Life Expectancy than the same species that live in rural areas. This is noise level also impacts birds communication and reproduction. For example males that want to breed must compete with the sound of cars and other loud noises otherwise they have no chance of reproducing the animals must make a greater effort. Thats why its becoming more important to create spaces for birds when planning cities its the only way to ensure long term biodiversity.
