If the world hopes to make meaningful progress on climate change, it won’t be enough for cars and factories to get cleaner. Our cows and wheat fields will have to become radically more efficient, too.
That’s the basic conclusion of a sweeping new study issued Wednesday by the World Resources Institute, an environmental group. The report warns that the world’s agricultural system will need drastic changes in the next few decades in order to feed billions more people without triggering a climate catastrophe.
