What Does Carbon Sink Mean?
A carbon sink absorbs and stores carbon compounds by removing carbon dioxide from the atmosphere in a process called carbon sequestration. The largest carbon sinks are natural, with the sea absorbing CO2 through biological and physiochemical processes and terrestrial plants acting as carbon sinks through the process of photosynthesis.
Safeopedia Explains Carbon Sink
Combustion of fuels and farm animal production add carbon dioxide to the atmosphere, contributing to global warming. The Kyoto Protocol promotes the preservation and creation of carbon sinks to offset carbon emissions and reduce global warming. For example, the amount of carbon produced through human activities is referred to as a carbon footprint and this can be reduced by planting trees that act as a carbon sink or carbon offset. A carbon source produces more carbon than it absorbs, while a carbon sink absorbs more carbon than it produces.
