Pollution - The Danger of Carbon Dioxide

       One of the causes of global warming is pollution. Pollution is contamination. Average air pollution resulting from motor vehicle exhaust fumes or factories. With the fumes, the air become dirty and we who breath it, will breathless. Even if we pollute the air with certain substance, air can become toxic.

       We are still make the wastes which can caused pollution. It can be said, If we continue to make the waste (limbah), pollution would not be inevitable. We must be smarter to treat the waste that exist and trying hard to restrore the natural resources which have been exposed to pollution. In fact, many ways to clean up a polluted natural resources.

       To restore land that has been contaminated, we can conserve soil. We can use reboisation. Plants can help to fertilized the soil and can absorb some chemicals from the soil. For water, we can do with the advanced techology of water filtration. The trick is to accumualate layers of sand, gravels, and ground in a drum. Then put the dirty water and if water has been flowing at the bottom of the drum, the water will be clean. The layers had been filter out impurities in the water so that water can be clean again.
