Water pollution
Basically, water contains more than 2 of 3 part of the earth's surface. Its composition has not only huge oceans like the Pacific, the Atlantic or the Indian ocean, but it also counts the freezing ice at the north and the south pole at the Arctic and the Antartica or various rivers among several countries. Therefore, water is undoubtly one of the most precious resources in our planet. However, human civilization has evolved and simultaneously generated a number of problems even the problem in water. The statistics from the Environment and Heritage Service(EHS) shows that the trend of water pollution have increased yearly since industrial revolution in Europe. Technically, water pollution can be categorized the sources as from commercial and household affair.
From the commercial sources, factories have been accused to be the main causal agent of water pollution. For years, various factories around the world have drained the contaminated water and waste water to the sea or river without any treatments and responsibilities. But shortly after stimulation from ISO(International Organization for Standardization) standard which the factories should follow because of the law or restriction depending on each country, water pollution from this source have considerably decreased. However, there are still other commercial affairs which constantly produce contamination to water such as chemical substances used in agriculture or even liquid used in car washer.
From the household affair, the percentage of polluted water production have been increased rapidly corresponding with the increased number of population. Without restriction in most countries, household cleaner, soap liquid, garden and lawn chemical substances can pollute directly to natural water sources. Especially in undeveloped and developing countries, mostly people have never realized about this problem. They may think that this problem should relate with only the commercial section.
In short, water pollution problem have changed the cause from commercial to civilian source. The optimistic aspect can be seen that the problem from the commercial side, once the major causal agent, have been successfully solved. However, household affair, once the minor cause, is now considered as the main attacker to water resource that, from now on, should have to be resolved.
