Answer:
C. Cutting down forests.
Explanation:
Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.
The effects of an increase in CO2 concentration in the atmosphere is as follows:
- increase in water contamination and floods
- ocean acidification
- reduction of cold-related deaths
However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.
When a factory is emitting large
amounts of CFCs into the atmosphere, it affects the people in that area by the increase
in the level of ocean water. CFCs dissolve in seawater and because they are not
reactive, they just circulate until it becomes saturated.
