Question

what environmental consequence is closely associated with the disruption of the carbon cycle by human activities?

• increased biodiversity
• global cooling
• ozone layer repair
• climate change/global warming

Explanation:

Human activities disrupting the carbon cycle (like burning fossil fuels) release excess carbon dioxide, which traps heat, leading to climate change/global warming. Increased biodiversity is not caused by carbon cycle disruption (it's more likely reduced), global cooling is opposite, and ozone layer repair is about CFCs, not carbon cycle. So the correct option links to climate change/global warming.

Answer:

D. climate change/global warming (assuming the last option is D; if options are labeled as per order, the fourth option: climate change/global warming)
