Burning Sugar Canes

When you burn sugar cane, it releases carbon dioxide into the atmosphere.
The farmer however only burns little sugar, which means that only a small amount of carbon dioxide will be released.

This small quantity can be absorbed by trees and then they, through the process of photosynthesis, can turn it into oxygen.
