Water Pollution is the contamination of water bodies. It occurs as a result of introduction of pollutants in water. Water is life. Still, we contribute in polluting the water bodies in several ways.
Water Pollution is mainly caused as a result of improper discharge of household and industrial chemicals wastes into the water bodies.
These dangerous chemicals (in the form of solid, liquid or gases) mixes with water and make it unsafe for living bodies. Water pollutants cause harm to human-beings, animals, trees and other constituents of environment.
Fresh water is the most important source of life on the earth. Any living thing may survive without food for days however it is impossible to imagine life without water and oxygen. The ever increasing human population enhances the demand of more water for purposes like drinking, washing, performing industrial processes, irrigating crops, arranging swimming pools and other water-sports centres. Water pollution is done by the people of all over the world because of increasing demands and competitions of luxuries life. Waste products from many human activities are spoiling the whole water and decreasing the amount of oxygen available in the water. Such pollutants are altering the physical, chemical, thermal, and biological characteristics of the water and adversely affecting the lives inside as well as outside the water.
When we drink the polluted water, harmful chemicals and other pollutants goes inside our body and deteriorates all the body organs functioning and puts our lives in danger. Such harmful chemicals also disturb the lives of animals and plants greatly. When plants absorb dirty water through their roots, they stop growing and die. Thousands of seabirds are killing because of the oil spilling from ships and industries. High level of water pollution is done due to the chemicals coming out of the agricultural usage of fertilizers, insecticides and pesticides. The effect of water pollution varies from place to place upon the type and amount of water contamination. The degradation of drinking water needs an urgent basis prevention method which is possible by the proper understanding and support from the end of each and every person living on the earth.
There is no denying that computer is one of the all-time greatest inventions of human being. It has brought us an endless number of benefits. This miraculous tool not only allows us to edit documents, to create excel worksheets or to install programs to serve our needs but also helps our kids relax with a wide range of games and apps. However, some people believe that computers may bring more harm than benefits if children use them daily; meanwhile, others state that they are helpful and can affect children positively. In my opinion, I totally agree with the first idea because of the following reasons.\nTo begin with, children will be isolated from other people around them if they use computers frequently. It’s simply because they spend most of their time on utilizing computers, so they do not have much communication with their parents. Moreover, when computers become their close friend, they may refuse to play with other kids as well as to take part in outdoor activities. It means there is less interaction between them and their fellows. Obviously, this is not recommended for children since they need to be active and to learn new things from family and friends to broaden their horizon. \nAnother point is that using computers uncontrollably may cause children to develop some diseases. Sitting in front of the computer regularly may lead to obesity because every day, children absorb a large amount of nutrition such as fat, protein and starch but they do not take exercises to consume this energy. Seriously, obesity can put them at higher risk of developing diabetes. Besides, some research has shown that looking at the computer screen continuously with concentration more than 2 hours will reduce our vision and cause myopia easily.\nThe last reason is that children can neglect their study and sink into computer games. It goes without saying that computer games are so addictive. If kids are unable to control themselves, they may spend all their time on playing games. After completing a level, they will have promotion to continue to play and to unlock new levels, then all these things will be repeated over and over again. In addition, computer games can inhibit the ability of thinking of children because they do not need to rack their brains a lot when playing games. Consequently, their study results may become worse and this will affect their future significantly.\nIn conclusion, I am totally in agreement with the idea that using computers daily will put great negative impacts on children. However, they can still take advantages of this wonderful invention if they use it suitably and effectively. Therefore, parents should teach their kids to be self-disciplined and to manage their time well when using computers.
