According to the Russian satellite news network reported that recently published "natural" magazine article said that in the depths of the ocean without some oxygen and no life, the thickness and the extent of the so-called "death zone" was significantly expanded in recent years, it is because of climate change and "killer" bacteria.

The formation of a low oxygen containing marine area called the "death zone" is the result of chemical fertilizer and industrial waste water pollution. Nitrate and other compounds in the river, and then flows into the nearby ocean, resulting in a large number of single cell algae rapid reproduction, they are dying and breeding in the water to absorb most of the oxygen. Most organisms cannot survive under these conditions.

Scientists have found that the "death zone" in the ocean increases will lead to climate change and global temperature rise, thus, the problem of hypoxia in the ocean will be more serious. In addition, a global climate change an "accomplice" -- a family of the SAR11 special "killer" bacteria exacerbated this phenomenon, and forced the "death zone" to increase at a faster rate.
