How does deforestation affect levels of carbon in the atmosphere?

• Trees remove oxygen from the atmosphere during photosynthesis. With fewer trees, more oxygen remains in the atmosphere.

• Trees remove carbon dioxide from the atmosphere during photosynthesis. With fewer trees, more carbon dioxide remains in the atmosphere.

• Deforestation removes the harmful chemicals from the environment that farmers use on crops.

• Deforestation adds more carbon dioxide to the air which is harmful for the environment.
