Why should pollution bother us?

While most developed countries have complete access to clean water and excellent sanitation, many third world undeveloped countries like africa and some parts of india have a lack of clean, drinkable water and proper sanitation due to the fact that these countries do not have the resources to purchase expensive water purification machinery to improve on their water quality and their citizens do not have enough money to purchase proper sanitation products. This allows waterborne diseases to spread quickly and easily, causing many unneeded deaths. Waterborne diseases like diarrhea, cholera and dysentery are caused by harmful microorganisms which are directly transmitted when contaminated fresh water is consumed. The statistics are alarming, with 1.1 billion people around the globe having no access to drinking water, 2.4 billion have inadequate sanitation and 3,4 million die from waterborne diseases yearly However, even developed countries will face the problems of pollution, due to the fact that we are constantly releasing pollution into the atmosphere as we burn fossil fuels to power our vehicles, it will cause our immunity system to become weaker, allowing infectious airborne diseases to spread easily. It will also cause environmental degradation around the polluted spot, causing nearby biodiversity and habitat to be destroyed. As biodiversity is crucial to the country’s growth, this may have a negative impact on the economy of the polluted country. Although pollution is a global problem, it also features more opportunities. Careers featuring pollution treatment are among the fastest growing economies, and it will also help to make a change among the lives of other people
