Choking Oceans: Elixir of Life – Healthy Climate (E)
The oceans, which make up over 70% of the Earth's surface, control the climate globally. They moderate temperature, influence weather patterns, and determine rainfall, floods, and droughts. With an estimated 83% of the world's carbon cycle passing through marine waters, they are also the greatest carbon repository on earth. This section of documentary discusses about some of these significant oceanic properties have changed over the time. In past one century the oceans have absorbed one-third of the carbon dioxide produced by humans due to which the chemistry of oceans is altering. As a result, the biodiversity of marine world is being considerably affected. Furthermore, chemicals from various industries are causing oxygen-depleted dead zones in which marine animals must struggle.
