Discuss how the human disruption of the carbon cycle has caused ocean acidification.

The oceans are one of the three major carbon sinks on the planet, meaning that they accumulate enormous amounts of the atmospheric carbon in them. While there is a natural balance between the storing of carbon in the ocean waters and the releasing of it in the atmosphere, except when there is dramatic changes, it seems that the humans now are becoming a big factor. The humans with their activities have started to propel much more carbon into the atmosphere than what the natural cycle propels. Big portion of that carbon is ending in the ocean waters. When in contact with the ocean waters, the carbon reacts with the water and it results in acidification if the amount of carbon is high enough. The acidification of the ocean waters changes the living conditions for the marine organisms, so lot of start to die out, and if that continues it can result in a mass extinction of the marine life.
