Soil
A carbon sink acts as a reservoir for carbon, removing carbon dioxide from the atmosphere, for almost an indefinite period of time. Preserving carbon sinks is significant in tackling climate change.
Explanation:
The soil has more carbon that atmosphere and life on earth combined. It is approximated that soil holds approximately 2,500 billion tonnes of carbon while the atmosphere holds approximately 800 billion tones. Plat and animal life combined hold about 560 billion tonnes of carbon. The carbon in the soil comes mainly from dead organic matter and microbes in the soil.
