Water covers over 70% of the earth's surface and it is a very important resource for people and the environment. Coincidentally, 70% of human body also made up of water. These show the importance of water in life. Unfortunately, this valuable gift has been polluted by human being. There are many causes of water pollution that need to be prevented. According to a research, 80% of pollutants in seas and oceans come from land-based activities. Excessive pesticides that flown into rivers can damage DNA and may lead to infant mortality. A part from that, industrial waste also contributes to this problem. The waste damage the health of aquatic animals and those who eat them. Furthermore, oil spill from ships' tanks worsen the situation. As a result, seabirds may get covered in the oil, then they cannot fly and sometimes, dead.Beside marine dumping, domestic waste from hotel often being channeled into seas. Polluted drinking water sourced from the seas can cause infectious diseases that may infect aquatic and terrestrial life. The diseases include cholera, typhoid, diarrhea, immune suppression,reproductive failure, and acute poisoning. Fortunately, there are many steps that should be taken to control the water pollution. Firstly, water treatment plants and septic tanks can be used to treat sewage. Other than that, excessive nitrate in soil can be leached through denitrification process. Last but not least, ozone generator is used to break down pollutant in water source. In conclusion, human being should appreciate water and take great care of it before it is too late.

  1. You entry is really brief and you have talked most about water pollution in general. I would like you to give more focus on a more significant aspect of water pollution, which I read in your link, the only link, what are the dangers of water pollution?. Maybe after this, you can find more sources on a more detailed topic such as that. I like the design you chose for your blog.
