Marine environment is one in water,seawater tolerance hydrolyzate and suspended solids,seabed sediment and marine organisms,including complex systems.Ocean rich biological resources,mineral resources,chemical resources and power resources is an indispensable resource treasure house of human beings,with human survival and development of the relationship very close.
The main objective of the current marine conservation is to protect the living marine resources,so as not to failure,in order for human sustainable use.In particular,give priority to protect those valuable and critically endangered marine life.According to the UN for investigation,due to overfishing,accidental capture and killing of non-target to allow hunting of marine,coastal shoreline construction,mangrove deforestation,widespread marine pollution,at least the world's 25 most valuable fishery resources depleted,whales,sea turtles,manatees and many other marine animals face extinction risk.Is expected that with the expansion of the scale of ocean development,
Marine living resources are likely to cause more damage.
The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat,in particular,their migration,spawning,foraging,avoiding predators coast,tidal flats,estuaries,coral reefs,it is necessary to prevent the heavy metals,pesticides,oil,organic and easy to produce nutrients such as eutrophication of marine pollution.Preservation of the marine living resources of the natural regeneration capacity and water purification capacity,preservation of the marine ecological balance,to ensure sustainable human development and utilization of the oceans.
