Question

ТО
Explain how human activity can affect the carbon cycle.

Answer 1

Human activity can affect the amount of carbon in the atmosphere. When fossil fuels like oil, coal, and natural gas are burned, carbon dioxide is released into the atmosphere as waste. The clearcutting of forests for lumber and fuel also increases levels of carbon dioxide in the atmosphere because the trees can no longer remove carbon dioxide from the atmosphere for photosynthesis. If trees are burned in order to be cleared, the burning processes release even more carbon dioxide into the air.

Step-by-step explanation:

Answer 2

Human activity can affect carbon cycle because of the burning fossils fuels, changing land use, and by using limestone to make concrete all transfer significant quantities of carbon into the atmosphere
