This process is called “sinking.” Carbon sinks, generally refers to the process of removing carbon dioxide from the air, activities, mechanisms. Speaking of carbon sinks, we must first mention global warming, referring to the increase of carbon dioxide. This refers to the carbon source, carbon source is the source of carbon dioxide. Carbon sources in nature are mainly ocean, soil, rock and organisms. In addition, industrial production, life, etc. will produce greenhouse gases such as carbon dioxide. it
