@BrownHairedEevee It's Foer's argument that in order to really have a positive impact on the climate crisis individuals will need to choose to make lifestyle changes. He argues that true, lasting climate change won't be achieved through renewable energy, electric cars, carbon taxes, etc., but rather through what we choose to eat. That by not eating animal products for (at least) breakfast and lunch we can bring about exponentially more benefit to the environment than any of the other "popular" things combined. The "popular" solutions will help, but if we don't change the way we eat, they won't help enough in time. 
I thought the book was rather engaging, and I appreciated his honesty when talking about his personal challenges to make different food choices. I'm curious who else may have read it and what their take on it is, because his arguments make a lot of sense to me.
