Meat-packing plants dump blood, the contents of entrails 内脏, and other animal wastes.
Other food-processing plants discharge fruit and vegetable skins, seeds, leaves, stems, and other vegetable wastes.
Oil spills from tankers at sea or leaks from underground storage tanks on land are very difficult to control
Oil spills at sea decrease the oxygen level in the water and cause grave harm to the creatures living in the sea.

As water moves along or beneath the surface of the Earth, it dissolves minerals and matter from decaying plants and animals.
The principal positive ions (cations) in natural water are sodium (Na+), potassium (K+), calcium (Ca2+), magnesium (Mg2+), and sometimes iron (Fe2+ or Fe3+).
Domestic sewage contains a wide variety of dissolved and suspended impurities: a. organic materials-food and vegetable waste b. plant nutrients- chemical soaps, washing powders c. disease-causing microbes微生物

WATER POLLUTION
Yangzhou, China Miles
The four basic natural resources are water, air, land and energy. We need water for multiple uses and a certain quality is required. Its use leads to the generation of wastewater that can cause an impact on the environment.
As far as future prospect is concerned, I am sure that good results will be achieved in this respect. Rivers which used to be contaminated by industrial wastes will be cleaned and fish which could not live there a few years ago will be again. To conclude, it seems obvious that tomorrow will be better and brighter only if everyone does his part and tries hard to seek solutions for its control.
In addition, factories in towns and cities must be prohibited from draining waste liquids into rivers before they are totally treated and purified. I feel if they violate relevant rules or laws, they should be fined heavily. Certainly, there are some other cures which are worth adopting.

Marine environment pollution
Ocean oil leak, Marine transportation ,various landsourced pollutants (mainly coastal industrial wastewater and life sewage) discharged into the sea , aggravating the Marine environment pollution, and the Marine ecological environment has deteriorated.
A large number of nutrient-rich human sewage, industrial wastewater, agricultural wastewater emission sea of ​red tide organisms will use nutrients such as nitrogen, phosphorus, carbon frantically breeding and accumulation induced red tide occurred.
Measure：Sewage marine disposal
Ocean disposal of sewage is prohibited or effective measures to limit emissions and freedom of sewage shore random row, concentrated pretreatment of sewage works system, transportation by pipeline to the underwater depth of the ocean, emissions by the diffuser, so that inas small as possible within a high degree of dilution, to reduce the impact on the environment. This sewage marine disposal engineering, compared with the conventional secondary treatment of sewage, saving 1/2 to 1/3 of investment in infrastructure and operation and management costs, covering 30 to 40 percent reduction in benefits are enormous.

conclusion
Over the years, the Chinese people's awareness of resource protection is weak and the legal concept is thin. We often destruct at first and protect when situation is terrible, so many land aquatic organisms and marine life have disappeared from our sight. As a result of Kinds of reasons, the Chinese marine biodiversity and the marine environment isstill is worrying.
