Question

Which human activity would most likely decrease the amount of carbon in the atmosphere?

A. clearing forests
B. heating coal
C. burning wood
D. planting trees

Answer 1

The fourth option.

Also known as "D."

I chose this option because as trees grow, they remove Carbon Dioxide from the atmosphere. Carbon Dioxide is used in a process called "Photosynthesis" in which plants make there own food using Carbon Dioxide, sunlight, nutrients from the soil, water, etc.

The product produced would be Glucose and Oxygen.

Since Carbon Dioxide would be taken from the plants to make food and breathe, the level of Carbon in the atmosphere would definitely decrease!

Answer 2

`\huge\boxed{\sf Option\ D.}`

Step-by-step explanation:

Trees absorb carbon dioxide and release oxygen. In this case, carbon dioxide in the atmosphere decreases and oxygen in the atmosphere increases.

Hence, we should plant more trees in order to decrease the amount of carbon dioxide in the atmosphere which is the main cause of global warming.
