IELTS TEST 2 (WATER POLUTION)
Pollution of rivers, lakes, and seas is a major concern for people who seek to protect the environment. What are the causes of water pollution? And what effects does this have on animal life and human society?
Water bodies such as rivers, lakes, and seas are suffered by toxic pollutants coming from hazardous chemicals and plastics. This issue becomes close attention of environmentalists as it causes a poison ecosystem for aquatic animals and health problems for a human.
The pollutants that cause major damage in water ecosystem are from harmful chemicals and solid waste. This toxic compounds such as mercury and asbestos is mainly a result of industrial disposal discharged without any treatments, and it is undeniable that even the highly productive companies do not have a well-operated system to reduce the concentration of such contaminants. In fact, the more active of this process means the more plastics will be needed for packaging which majority of them will be accumulated into the water bodies as the final disposal place. For example, European Union surveyed and revealed that at least 61% of plastics ended up in the sea during a decade ago, and there is an area called barren Ireland where it is almost empty with sea creatures resulted from mercury contamination. If there is no effort to prevent or reduce the amount of disposal, the floating of these harmful compounds will substantially increase of sea covered by the waste.
What are the major consequences of this? These pollutants will both danger aquatic animals and human's health as the water becomes poisonous, and some of the animals are vulnerable consuming plastic compound as their prey has similar appearances. The further impact may lead to numerous deaths of creatures and chronic diseases attacked people who consume toxic seafood. For example, on the north coast of Ireland, some death turtles found contained plastic pieces in their digestive track. Also, in hospital, the doctor has recorded 20 people in that area suffer from mercury toxicities after eating fish in the coastal. Therefore, these are the reason why many environmentalists putting major concern in order to avoid the adverse effect in the future.
In conclusion, water pollution from industrial waste mainly chemical substances and plastics cause severe disadvantages both aquatic animals and humans.
