As you may have guessed, not all foodstuff uses the same energy to create too.
Have you ever wondered what’s up with the whole vegan craze thing? Ellen Degeneres, Anne Hathaway, even Mike Tyson have all switched to “rabbit food”.
You probably already know (totally not because of stereotyping hippies) that being vegan has something to do with saving the environment.
And now you’ll know why!
Food that has to be flown is worse. After all, transport eats up energy too, remember?
Everything is always in stock in the supermarket, but their carbon footprint across the globe is not the same.
Fruits and vegetables that are out of season have to be flown in. That’s why in the U.S., the ratio of fossil fuel energy and the energy we get from food is 10:1.
And that is definitely not sustainable when you consider how much food gets wasted, and how limited our energy sources are becoming.
