ocean life on mass extinction

Here's your daily dose of Earth preservation. The ocean are now undergoing mass extinction, according to scientist, you can blame that on over-fishing and global warming.

The proves of coral reef dying around the world and increasing area call the "dead zone", this area are basically where the oxygen are so low that no living organisms can live in it, it is real, and it is spreading.

It is also said that we will lose major ocean ecosystem in a single generation. This is a real risk, much more bigger than previously thought. The ocean are facing the deadly trios, acidification, higher temperature and lack of oxygen. This trio is an evidence of mass extinction in the past.

The source are clear, acidification cause by the absorption of carbon dioxide by the use of fossil fuel, which also heating up the planet, while the low oxygen area are cause by run-off of fertilizers and other man made substance.

Unlike global warming, over-fishing is entirely different problem. It can be regulated by strict policy and tighter law. Over-fishing in some area across the globe has resulted in the extinction of some species even bring them to the brink of extinction.
