The Impact of Human Activities on the Greenhouse Effect

How do human activities affect the natural greenhouse effect?

a. exacerbate the natural greenhouse effect.

b. create the greenhouse effect.

c. diminish the greenhouse effect.

d. eliminate the greenhouse effect.

Final answer:

Human activities, chiefly burning fossil fuels and deforestation, exacerbate the natural greenhouse effect by increasing the levels of greenhouse gases in the atmosphere, thereby causing additional warming known as global warming or climate change.

Explanation:

Human activities, specifically those related to the burning of fossil fuels and deforestation, primarily exacerbate the natural greenhouse effect. The greenhouse effect is a natural phenomenon where gases in the Earth's atmosphere trap heat from the sun, which warms our planet and makes life possible. However, increased levels of greenhouse gases caused by human activities enhance this effect, leading to additional warming commonly referred to as global warming or climate change. None of the options stating human activities create, diminish, or eliminate the greenhouse effect are correct, as these activities only enhance the existing natural effect.
