What is the function of carbon sinks?

Carbon sinks play a crucial role in regulating the levels of carbon dioxide in the atmosphere by absorbing more carbon dioxide than they release. This process is essential for mitigating climate change, as increased concentrations of CO2 contribute to global warming. Natural carbon sinks include forests, oceans, and soil, which capture carbon dioxide during processes such as photosynthesis in plants or through the biological processes occurring in oceans and soils.

The ability of these sinks to maintain a net absorption of carbon dioxide is vital for balancing the carbon cycle. This balance helps to keep atmospheric CO2 levels stable, thus reducing the greenhouse effect and its associated impacts on climate systems. By enhancing the capacity of carbon sinks, we can help combat the negative effects of climate change.

While some choices may mention aspects related to carbon emissions or industrial activities, none fulfill the primary role that carbon sinks play in carbon absorption and climate regulation as highlighted by the correct answer.
