Burning fossil fuels releases carbon dioxide into the atmosphere, contributing to greenhouse gases. Deforestation contributes to greenhouse gases because trees absorb carbon dioxide and release oxygen, so cutting down trees reduces this natural process. Solar power does not contribute to greenhouse gases.
