water pollutionThe Earth is our home, but now it is severely polluted by human activities. The main sources of pollution are listed as follows:
Firstly, air pollution caused by burning fossil fuels such as coal, oil and gas. Exhaust gases such as carbon dioxide, nitrogen oxide and sulfur dioxide, can cause the greenhouse effect, leading to global warming and so on.
Secondly, water pollution is caused by dumping industrial, agricultural and domestic wastewaters, resulting in water shortage, eutrophication of lakes and serious water pollution.
Thirdly, land pollution caused by improper disposal of garbage and pollutants such as chemical fertilizers, pesticides and industrial waste.
Fourthly, noise pollution caused by various man-made noises, such as traffic noise and construction noise, which can cause hearing damage, sleep disturbance, and so on.
Fifthly, light pollution resulting from artificial illumination at night, which can cause poor visibility and damage the eyesight of people.
We should work together to protect our earth, not just talking and discussing, but really implementing the green technologies. As individuals, we should save resources, reduce consumption, reduce emissions and develop low carbon lifestyles. We should also strengthen environmental pollution prevention and control, implement the law, tighten restrictions, and enhance the punishment of environmental pollution offenders. It is a long process, but it is necessary. If we can all work together, we can make the Earth a better place to live in.
