The Obama administration is taking on agriculture’s role in climate change
When we talk about why the planet is warming, we talk about fossil fuels — oil, gas, coal and their many variants. What we rarely say or think to say, though, is that’s not the whole story.
The fact is that plants take in carbon dioxide in the process of photosynthesis, and release it again when they die. So if you clear large swaths of land, so that it does not contain as many trees, crops, or grasses as before, then you are also contributing to global warming.
