Pollution

 

Pollution is the introduction of contaminants into the natural environment that cause adverse change. There many forms of pollution, for example, air pollution, noise pollution, water pollution, radioactive contamination and many more. 

   Air pollution refers to the release of chemicals and particulates into the atmosphere. The common gaseous pollutants which will result to air pollution includes carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs) and nitrogen oxides. These gaseous are normally released by the industry and motor vehicles. Noise pollution then includes roadway noise, aircraft noise, industrial noise as well as as high-density sonar. Water pollution is caused by the discharge of waste water from commercial and industrial waste through intentionally or spills into the surface of the waters； discharge of untreated domestic sewage and chemical contaminants such as chlorine; release of waste and contaminants into surface runoff flowing to the surface waters; waste disposal and leaching into groundwater; eutrophication and littering. Radioactive contamination is result from 20th century activities in  atomic physics, such as nuclear power generation and nuclear weapons research, manufacture and deployment. Radioactive pollution is a serious pollution issue with the concern of international societies. 

   All forms of pollution will bring negative effects to our Mother of Earth, and of course to human beings. For the effect of human health, the air pollution which resulted from the release of chemical gaseous can cause respiratory disease, cardiovascular disease, throat inflammation, chest pain and congestion. Water pollution will also caused death because of the contamination of drinking water which contained untreated sewage. The problem of contamination of drinking water is happened in most of the developing countries such as India and Afrika. Millions of people had dead due to the air and water pollution every year. Oil spills, which is another source of water pollution, will skin irritations and rashes. Besides, the radioactive and chemical substances that release by the radioactive industry can cause cancer and birth defects. Radioactive pollutions will affect many generations of affected area. In aspect of environment, the air pollutants or called greenhouse gases will leads to global warming which effects ecosystems of our environment. The release of sulfur dioxide and nitrogen oxides can cause acid rain which will lower the pH value of soil. All these pollutants will greatly affect our environment and our Mother of Earth. 

   Who needs to take the responsibilities of these effects on our earth? The human being is. In February 2007, a report by the Intergovernmental Panel on Climate Change (IPCC), representing the work of 2,5000 scientists, economists and policymakers from more than 120 countries , said that humans have been the primary cause of global warming. We, the citizens of the earth, are the one who destroy our own home. We should take actions to avoid our earth being continue polluted by us. Stop pollution!humans!We are not living to destroy the earth but protect it to be harmed. Therefore, we need to control the pollution. Without pollution control, the waste products from consumptions,heating, agriculture, mining, manufacturing, transportation and other human activities will degrade our environment. We need to practice pollution prevention and waste minimization practices in our daily lives. For example, practice the 3R in our daily lives: Reduce, Recycle and Reuse. The industry should have take action to reduce the release of pollutants in order to control the pollution. The Kyoto Protocol is one of the effort to reduce the global warming phenomenon. Countries which ratify this protocol commit to reduce their emissions of carbon dioxide and five other greenhouse gases, or engage in emissions trading if they maintain or increase the emissions of these harmful gases. A total of 141 countries have ratified this agreement. 

   However, these efforts are not enough. People should aware of how their irresponsible action will bring consequences to themselves. Start to preserve our Earth today by minimizing the waste. Reduce the usage of plastics, using public transportation instead of motor vehicles, do not waste water, do not throw rubbish all over the place-these are the small efforts that we can easily do to save our environment. What's you waiting for? Start to do it now!
