Impose Strict Standards on Industries
Some parts of the world farce grave soil pollution that jeopardizes the ecology, food safety, people's health and a sustainable social development. The long-term effect of land pollution has become a cause for concern by the public in general, In my opinion, strict regulations and standards for industry should be adopted in order to prevent land pollution.
Firstly, as a matter of fact, industrial pollutants account for more than 80% of the land pollution which is now causing us huge problems in every aspect of our lives. By setting strict standards on industries, we could effectively deter relative factories from producing industrial pollutants. For example, the Earth Summit in Rio de Janeiro marked a paradigm shift in the attitude of the governments of the world, as 150 delegates attended and recognized the importance of control and discipline. Secondly, when governments make the new standards for those leading industries and with people in every comer of the world benefiting from it, small business owners and entrepreneurs will also be positively involved and possibly stay engaged with the process of reducing land pollution.
To conclude, I am fully convinced by what is argued above that for the sake of ourselves and the generations to come, strict relative relations and standards for industry should be immediately adopted in order to prevent land pollution once and for all. (224words)

New Technology Is One Way to Solve Noise Pollution
There have been an increasing number of complaints and lawsuits about noise pollution in some major world cities. The problem with noise is not only that it is unwanted, but also that it negatively affects human health and well-being. In my opinion, the government should attach importance to the research and application of technology in order to reduce noise pollution.
First, the application of sound-absorbing or sound-insulation material shows the quickest sign of the reduction of noise pollution. Noise inside a building can be reduced if both the external and internal walls are made of sound deadening materials. Heavy and dense materials such as masonry or brick walls are better for sound reduction. The application of sound reduction materials is economically and technically feasible in dealing with four main noise sources, namely transportation, industrial production, construction, and social activities. Furthermore, the introduction of hybrid cars has made advances in the reduction of motor vehicle noise. Noise from transportation is one major source of noise pollution. The application of cars with low level noise will be effective in reducing noise emission.

Use Clean Energy Only
The world is facing an uphill battle to reduce air pollution which has led to a series of health hazards. In my opinion, the real solution to air pollution is to replace fossil fuels with clean energy like solar and wind energy.
Firstly, by utilizing the sun and the wind to produce clean energy, pollution from dirty energy such as fossil fuels can be greatly reduced. The overuse of fossil fuels such as coal has given rise to the emission of pollutants like nitrogen oxides and carbon dioxide which are looming as one major threat to air quality. According to the official statistics, carbon dioxide emission reached 18.57 million tons in 1999, posing a serious threat to air quality, Therefore, harnessing solar and wind energy can effectively reduce pollutants emission from fossil fuels and significantly improve air quality. Secondly, renewable forms of energy such as solar and wind energy are non-polluting and environmentally friendly, It is widely acknowledged that solar and wind energy are clean, free and inexhaustible. They provide energy for cooking, lighting, heating and cooling without any direct emissions.
In conclusion, to win the battle against air pollution, some urgent measures have to be carried out immediately. Replacing fossil fuels with sustainable clean energy is the top priority. (211 words)
