According to professor of geophysics Daniel Rothman, a mass extinction of marine species is likely to occur if we overload our oceans with an amount of 310 gigatons of carbon (Rothman). This is due in 2100, he also predicts, bearing in mind that human activities are on the rise. It is a fact that the planet has endured a noteworthy climate change and the water temperature has risen dramatically because of the industrial activities of the last century. A high water temperature causes a drop in oxygen levels and makes it difficult for marine organisms to make use of the oxygen left. The Baltic Sea also happens to suffer from a lack of oxygen which leads to the death of animals and plants. (Castensen). In addition, Dr. Schmidtko’s study has come to the conclusion that the ocean’s oxygen content has decreased by more than two percent over the last 50 years (Schmidtko)
