Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide (CO2) to reduce the effects of climate change. This can occur naturally through ecosystems like forests, oceans, and soil, which absorb CO2 from the atmosphere. In addition to natural methods, there are also technological approaches, such as carbon capture and storage (CCS), where CO2 emissions from industrial sources are captured and stored underground. Both methods aim to lower the concentration of greenhouse gases in the atmosphere, helping to mitigate global warming and its impacts.
