The reason I thought GMOs were important to include in this book is because they are a great way to help us tread more lightly on the planet. They cause the crop yield to increase and you can grow GMO plants in different places. If climate change happens, you're going to need plants that can survive heat waves and droughts. The GMO toolkit is our best toolkit for accomplishing those things right now, and yet it's stridently opposed by governments and all kinds of groups around the world.
