Environmental pollution is the state of the environment contaminated by chemical, biological ... affect human health, other living organisms. Environmental pollution is caused by humans and how to manage people.
The major forms of pollution:
- Air pollution, dust and smoke from the release of chemicals into the atmosphere. Examples of toxic gases is carbon monoxide, sulfur dioxide, cloroflorocacbon substances (CFCs), and nitrogen oxide is industrial waste and vehicles.
- Water pollution occurs when water flows through the surface of household waste , industrial waste water, the contaminants in the ground, and then seeps into the groundwater.
- soil pollution occurs when soil contaminated with toxic chemicals (concentrations exceed normal limits) by activities all human activities such as mining, industrial production and use of chemical fertilizers or pesticides so much, ... or leaked from underground storage tanks. The most common pollutants in the soil are hydrocarbons, heavy metals, MTBE, herbicides, pesticides, and other chlorinated hydrocarbons.
- Radioactive pollution, noise pollution, light pollution .. .
effect:
+ for human health: air pollution can kill many living organisms, including humans. Ozone pollution can cause respiratory disease, cardiovascular disease, inflammation of the throat, chest pain, breathlessness.

Oil spills can cause itchy blisters. Noise pollution caused deafness, hypertension, depression, and insomnia., Causing serious consequences.
+ For ecosystems:
- sulfur dioxide and nitrogen oxides can cause acid rain reduces soil pH.
- contaminated soil can become barren, unsuitable for crops. This will affect other organisms in the food web.
- Smoke and fog reduce sunlight that plants get to perform photosynthesis.
- Invasive species can account for environmental competition living and doing harm to native species, thereby reducing biodiversity.
CO2 generated from factories and other passing vehicles also increases the greenhouse effect. Earth warmer days. Gradually destroys the natural resorts that are available.
The solution to limit environmental pollution:
- Reducing soil salinity.
- Handle contaminated natural water.
- Making clean air ...
