The Role of Carbon Sinks in Climate Change Mitigation

Carbon sinks, both natural and artificial, play a crucial role in absorbing atmospheric carbon dioxide. Natural sinks like oceans and forests use biological processes to capture CO2, with oceans absorbing about 50% of emissions. However, these sinks have limitations, such as ocean acidification. Artificial techniques aim to enhance carbon sequestration but face efficiency challenges. While carbon sinks help combat climate change, reducing fossil fuel dependence and increasing renewable energy use are essential for long-term solutions.

What are carbon sinks primarily responsible for?

• Increasing atmospheric oxygen

• Absorbing carbon dioxide from the atmosphere

• Producing fossil fuels

• Generating renewable energy

Which natural feature is considered the main carbon sink?

• Forests

• Deserts

• Oceans

• Mountains

What role do plankton and algae play in carbon sequestration?

• They increase ocean temperature

• They produce methane

• They absorb carbon dioxide

• They release carbon dioxide

How do forests contribute to carbon sequestration?

• Through the process of photosynthesis

• By increasing biodiversity

• By releasing carbon into the atmosphere

• By storing carbon in the soil

What is a major limitation of natural carbon sinks?

• They can only absorb oxygen

• They are not affected by human activities

• They can cause global warming

• They have a maximum absorption limit

What is a consequence of exceeding the absorption limit of oceans?

• Decreased sea levels

• Ocean acidification

• Enhanced coral growth

• Increased fish population

What is the purpose of artificial carbon sequestration techniques?

• To increase fossil fuel production

• To extract and store carbon from the atmosphere

• To enhance oceanic biodiversity

• To reduce renewable energy usage

What is a current challenge faced by artificial carbon sequestration technologies?

• They are too efficient

• They cause carbon leakage

• They are widely adopted

• They increase atmospheric carbon

What is essential to combat climate change effectively?

• Commitment to renewable energies

• Increased use of fossil fuels

• Dependence on natural carbon sinks

• Reduction in oceanic activities
