Showing the hidden costs of the things we buy | J Henry Fair | TEDxBerlin
Photographer J Henry Fair takes aerial photos of areas in environmental crisis around the world, to show how industry and the consumer affect the planet. At TEDxBerlin, he gives an annotated tour of his shocking, beautiful work, explaining how these photographs show the “hidden costs” of the things we buy – things like toilet paper, hairspray, gasoline, even power for our homes.
Why I create pop-up farms in my city | Roman Gaus | TEDxZurich
Creating a farm in the midst of a city isn’t exactly easy, but at TEDxZurich, urban farmer Roman Gaus makes it seem both easy and fun. He and colleagues install pop-up farms in random places all over Zurich with the help of recycled corrugated containers, plants and fish.
The street lamp that absorbs CO2 | Pierre Calleja | TEDxLausanneChange
At TEDxLausanneChange, French biochemist Pierre Callej shares his idea to use algae to power street lamps. He and his team developed a lamp that doubles as a habitat for microalgae, which absorb solar energy and consume carbon dioxide. These lamps are designed to store the energy made from this process, so that when placed in unlit places, they continue to shine.
