Pollutions

Air Pollution

The situation: this kills over 2 million people each year. The amount of CO2 and methane gases in the air has developed a new disease in China called the Beijing cough. Moreover, beside health dangers, the more gases are introduced into the air, the more heat is trapped, creating global warming.
The causes: Along with the advancement of many industries all over the world, more gases are belched out of factories and industrial facilities. Many incidents such as Chernobyl further devastate the air. Increasing demands for fossil fuel for everyday lives, such as to power cars and vehicles, is also a contributor. More cars and machines that are powered by fossil fuel, more CO2 dioxide is emitted.

The solutions: We need to find better alternatives to create power such as solar and wind power. As the result, we rely less on fossil fuels, in turn, reducing the amount of CO2  and other gases being introduced into the air. As citizens, people must be aware of the situation and voluntarily join the campaign. We could reduce every person's carbon footprint by recycling, and using public transportation. The governments are taking measures to reduce CO2 emission through the Kyoto protocol.

Water pollution

The situation: Worldwide, 750 million people lack access to clean water. That's 2 1/2 times the population of the United States. More,only 2.5% of the world's reserve is fresh water. 15 million children of age five or under die because of drinking unsafe water.
The causes: 70% of industrial waste and chemicals are dumped into water bodies which later contaminate the drinking water. The lack of awareness of citizens of developing countries also contributes to this. This mostly includes littering on beaches and into water bodies such as ponds, lakes, or rivers.

The solutions: More research and studies should be conducted toward inventing technologies to purify water. Governments must enforce laws on waste process and removal.

Light Pollution:

The situation: Light pollution has a negative impact on ecology. Birds are singing at unnatural time. Sky glow, brought about by light pollution, makes it difficult for astronomers and amateurs to observe the stars. Also, plants growth, development, and flowering could be disrupted or altered by artificial light.
The causes: Human is the source of light pollution because we are the ones who introduced artificial light into the environment.
The solutions: We should improve the lighting plants. Reduction of light usages is necessary. Turn off the lights when you go out. Turn off the light when ever no one is in a room. Also, we need to upgrade the lighting technologies so that they won' disrupt the natural ecology.

Why do we need some pollution?
The CO2 pollution has turned plants into better CO2 processing machines. We could potentially introduce more aerosol into the air because it reflects sunlight back into space. This would reduce the accumulation of heat and potentially reduce global warming. Moreover, it would also promote plants growth to process CO2.
