Question

what environmental consequence is closely associated with the disruption of the carbon cycle by human activities?
climate change/global warming
ozone layer repair
global cooling
increased biodiversity

Explanation:

Human activities like burning fossil fuels release excess carbon dioxide. This disrupts the carbon cycle. Carbon dioxide is a greenhouse gas. Greenhouse gases trap heat in the atmosphere. Trapped heat leads to climate change/global warming. Ozone layer repair is not related to carbon cycle disruption. Global cooling is the opposite of what excess carbon dioxide causes. Increased biodiversity is not a consequence of carbon cycle disruption by humans (human - caused carbon cycle disruption often harms biodiversity).

Answer:

climate change/global warming
