Think about the impact of a filet mignon or a hamburger :

18% of all carbon footprint is created by cattle.

70% of all agricultural land is used to raise cattle.

That 70% is translated into 30% of all the Earth's land mass.

You have to see this talk in its entirety. It totally and absolutely rocks. Bittman gives us a short history of "what went wrong with what we eat", by focusing on the industrialization of food, the suburbanization of communities and the increase of women in the work force.

It is a fascinating walk through history and a provocative one as well : Is a salmon that was raised "organically" in Chile, packed in styrofoam and flown across the hemisphere in a jet really healthy?

Yet the core message of this video is simple : We need to reduce the production of food in factories. We need to cut out as much meat out of our diet as possible. We need to focus on seasonality and local produce.

More importantly we need to go back to having a majority plant based diet. Not just four own individual health, but because it's the only way we'll save the Earth from ecological disaster.

Watch it!
