Scientists are telling us unanimously that our use of carbon based fuels is changing the balance of gases in our atmosphere. Of course, we have to stop burning so much fossil fuel. But we also have to start taking carbon out of the air and ‘sequestering’ or storing it somewhere else. Luckily, nature already has a way of doing this. It’s called photosynthesis, and green plants do it all day long. They take carbon dioxide out of the air and store it in their bodies. Their roots also carry it deep into the soil and store it underground.
