We need to defend our oceans

Scientists are worried. If we don't create an establishment of marine reserves, a lot of marine species will disappear in the next few years.
Inside the reserves, scientists think populations of fishes  will increase in size and individuals live longer, grow larger and develop increased reproductive potential.

Reserves are supposed to be areas that are closed to all extractive uses, such as fishing and mining, as well as disposal activities. Human activities won't be allowed in these zones. 

Marine reserves are not just about overfishing - even if one of the primary reasons for creating marine reserves is preserving fish stocks. They are seen as an essential global tool to protect the marine environment, including from pollution caused by the disposal of wastes (radioactive wastes, munitions and carbon dioxide).
