Pollution is one of the phenomena that occurs due to reckless human activities. Such as industrial waste, car smoke, factories and greenhouse gases. These human actions cause a lot of damage to living species, our air and even our food. This essay will discuss the causes and effects of pollution with all types of pollution. The most common type is air pollution and is the most dangerous. People living in big cities are very familiar with air pollution. but there are different types of air pollution, some visible, some not, that lead to global warming. Generally, any substance that interrupts contact with the atmosphere and has harmful effects on the atmosphere is considered air pollution. There are many types of greenhouse gases. The most common or popular type is carbon dioxide. Carbon dioxide is the main pollutant that is warming the Earth. Carbon dioxide is widespread and is associated with automobiles, airplanes, factories and other human activities involving fossil fuels and the burning of gasoline, such activities have caused the level or ratio of carbon dioxide in the atmosphere to increase . So most living creatures and species breathe carbon dioxide while it is in the air. Finally, CFCs used in radiators and cooling systems and aerosol propellants. But they are now banned because of the noted effect they have on the ozone layer. CFCs interact with ozone and remove it and then replace it with other gases that are not needed in the atmosphere, or in another language creates new harmful gases. (Conserve Energy Future, 2014) The second type of pollution is water pollution. Since water is essential to our lives, it is important to protect it. Water pollution occurs when any matter... in the middle of paper... is sterile and no longer dries out, no matter what we try to do. The number of the earth's population is increasing every day, so the demand for food will also increase. Farmers, however, sometimes use toxic fertilizers, and with excessive use, the soil becomes poisoned. During mining and quarrying activities, several surface spaces are created and there is no natural way to refill these surface spaces. (Conserving the Future of Energy, 2014) It is crucial to control pollution because nature, wildlife and human life are precious gifts to humanity, so we must protect them and keep them safe, whatever the cost. Every step we take to keep our earth safe from all kinds of pollution will help us be protected from future disasters; however everything has its pros and cons, we just need to use the pros and avoid the cons.
