What is one way that humans depend on the earth's

People use plants as fuel for transportation and heat ... Fossil fuels store carbon, just as living trees and plants do. When burned, they release carbon dioxide into the air. The large and growing amounts of carbon dioxide in our atmosphere cause Earth's climate to warm.

Humans depend on Earth's nature, specifically plants to survive. For example, we need to consume plants to obtain its glucose and oxygen, so that we can have ATP energy. Without energy, we will die.
