  7. Disadvantages! • Burning the fuel creates carbon dioxide, a greenhouse gas. However , if you grow crops that absorb the same amount of carbon dioxide from the air that is created by burning them, the effect on the environment is less harmful. • Collecting waste in big enough amount to generate energy can be difficult. • If trees aren't groan especially for, fuel, and re-planted, the result is deforestation.
