Answers
Water pollution has a great impact on human health. Water pollution kills. It's been recorded that in 2015 nearly 1.8 million people died because of water pollution. People with low income are exposed to contaminated water coming out from the industries. Presence of disease causing pathogens in drinking water are the major cause of illness which includes cholera, giardia, and typhoid. Water pollution not only affects human health but also our environment by causing algal bloom in a lake or marine environment. Water pollution also causes eutrophication which suffocates plants and animals and thus causes dead zones. Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways and harm aquatic life.
Explanation:
Water being a universal solvent is vulnerable to pollution as it dissolves more substances than any other liquid on earth. Therefore, water is easily polluted. Toxic substances from farms, towns, and factories readily dissolve into water and mix with it, resulting in water pollution.Agricultural pollution is one of the major causes of contamination in rivers and streams. Use of excessive fertilizers, pesticides, and animal waste from farms and livestock operations lets the rain wash the nutrients and pathogens—such bacteria and viruses—into our waterways. The other major cause of water pollution is used water, termed as wastewater which basically comes from our sinks, showers, toilets and from commercial, industrial, and agricultural activities. It's been reported that the world's 80 percent wastewater flows back into the environment without being treated or reused. Oil spills and radioactive waste also causes water pollution to a great extent
It is important to keep our water bodies clean so we can take the following preventive measures to prevent from water pollution:Chemicals like bleach, paint, paint thinner, ammonia, and many chemicals are becoming a serious problem. Dumping toxic chemicals down the drain or flushing them down the toilet can cause water pollution. Thus, a proper disposal is important. Also, household chemicals need to be recycled.Avoid buying products that contain persistent and dangerous chemicals. Buying non-toxic cleaners and biodegradable cleaners and pesticides cuts down on water pollution.Prevent from pouring fats or greasy substances down the drain as it might clog the drain resulting in the dumping of waste into yards or basement which can contaminate the local water bodies.
