Q: What does burning wood release into the atmosphere?


Read this paragraph and choose the correct option from the provided answers:

Forests are also being destroyed. Trees may be cut down for their wood, or they may be burned to clear the land for farming. Burning wood releases more carbon dioxide into the atmosphere. You can see how a tropical rainforest was cleared for farming in Figure below . With forests shrinking, there are fewer trees to remove carbon dioxide from the air. This makes the greenhouse effect even worse.
