Why are rising carbon dioxide levels in the atmosphere harmful? Carbon dioxide blocks the sun’s rays from reaching earth’s surface.

Carbon dioxide harms plant life.

Carbon dioxide traps heat in earth’s atmosphere.

Carbon dioxide increases peoples risk of asthma.

C.) Carbon dioxide traps heat in earth's atmosphere

Explanation:

A.) is incorrect because it does not block the rays. Rather, it keeps the heat from the rays from escaping the atmosphere.

B.) is incorrect because carbon dioxide is actually necessary for plant life.

C.) is correct because carbon dioxide absorbs the heat that should be escaping the atmosphere. As a result, the heat stays within the atmosphere and increases Earth's temperature. This can lead to rising sea levels, loss of animal habitats, species extinction, etc.

D.) is incorrect because while increased carbon dioxide levels have been linked to worsening asthma, this connection is not direct and does not affect all age levels. This answer may be true, but there is a better, more obvious choice.
