Control of air pollution
1.Reduce the emission of all industrial pollutants. 2.Rational plan of industrial areas and nonindustrial zone. 3.Use public transportation system ,bicycles. 4.Use more clean and renewable energy , such as wind and solar power. 5.Plant more trees.
Control of noise pollution
1. Reduce the sources of noise 2.Use soundproof materials to build houses
3. Adopt anti-noise measures in urban construction.
Major water pollution sources



1.The discharge of untreated industrial waste water; 2.The discharge of untreated domestic waste water; 3.Extensive use of fertilizers, pesticides;
At last, for the government, they should
punish the individual and factory that pollute the environment harshly and reward those who contribute to the environmental protection. Also, the government can open a tip-off hotline and they should also encourage citizens to say more. What’s more, government should improve the system of public transportation in order to reduce the use of private cars.
The types of environmental pollution:
1.Air pollution 2.Water pollution 3.Noise pollution 4.Soil pollution
Major air pollution sources



1.Industrial production is an important source of air pollution. 2.The burn of gasoline and other hydrocarbon fuels in automobiles , trucks, and jet airplanes produces several primary pollutants. 3. Life stoves and heating boilers.
Control of water pollution
1. Reduce and eliminate emissions of waste water. 2.Strengthen the protection of drinking water source. 3.Adopt new agricultural science to reduce reliance on fertilizers and pesticides .
Some suggestions
Here I’d like to give some suggestions to protect environment.
First, for individuals, the environmental protection
is everyone's responsibility. As far as I am concerned, it is really important for every citizen to strengthen the awareness of environmental protection. Maybe we can not change the situations in a minute, but we can do little things to contribute one’s effort to the career of environmental protection, for example, we can minimize the use of one-time items, drive lowemission cars,etc.
Environmental Pollution
Please care for our Earth
The current situation of environment
With the development of industry and technology, the problem of the environment becomes a severe teset for our humans. There is a tendency that the environmental pollution is becoming more and more serious. So it is time for humans to come up with some effective methods to limit humans influence on the environment so as to solve this severe problem.
Control of Soil pollution
1. Adopt new agricultural science to reduce reliance on fertilizers and pesticides . 2.Waste water should be properly treated before discharging them on the soil. 3.Solid wastes should be properly collected and disposed off by appropriate method.
Secondly, as for companies and factories, I think
the way they produce products should be environmental friendly and the leader of the companies or factories should research and develop new equipments, which can reduce the pollution. Factories can use some advanced manufacturing technologies to reduce the noise and improve their capacities of recycling. Exhaust gas and waste water should be well disposed of before they are discharged.
Thanks for your appreciation！
