Question

question 3 of 30
why do some scientists argue against the use of carbon dioxide sequestration technologies?
a. the environment will naturally remove carbon dioxide on its own.
b. burning fossil fuels does not produce very much carbon dioxide.
c. trapping carbon dioxide uses a lot of energy and water resources.
d. there are few risks associated with trapping carbon dioxide.

Explanation:

Carbon - sequestration technologies involve capturing and storing CO₂. One major concern is the high energy and water requirements for trapping CO₂. The environment's natural CO₂ - removal capacity is not sufficient to counteract human - induced emissions. Burning fossil fuels is a major source of CO₂. And the risks associated with CO₂ trapping are not few.

Answer:

C. Trapping carbon dioxide uses a lot of energy and water resources.
