What is the main idea of the passage? Human activity, such as burning fossil fuels and clearing forests, is a primary cause of increasing carbon dioxide into the Earth’s atmosphere.

Humans add carbon dioxide to the atmosphere faster than the Earth’s biological processes can remove it.

The burning of fossil fuels contributes to the increase of carbon dioxide in the Earth’s atmosphere.

Since carbon dioxide contributes to climate change, it is important to understand where and when carbon is released into the atmosphere.
