A carbon sink is a natural feature that absorbs or stores more carbon than it releases.
(A)
Carbon sinks have been able to absorb about half of this excess CO2, and the world’s oceans have done the major part of that job. They absorb about one-fourth of humans’ industrial carbon emissions, doing half the work of all Earth’s carbon sinks combined.
(B)
Its mass of plants and other organic material absorb and store tons of carbon. However, the planet’s major carbon sink is its oceans. Since the Industrial Revolution began in the eighteenth century, CO2 released during industrial processes has greatly increased the proportion of carbon in the atmosphere.
(C)
The value of carbon sinks is that they can help create equilibrium in the atmosphere by removing excess CO2. One example of a carbon sink is a large forest.
