Hello there here we are again with yet another essay. this time we have the most common water pollution essay that appears in the majority of exams for students.
Water Pollution is the Contamination of water by harmful substances, which affects life on earth, is termed as water pollution. Due to human activities, our water is getting more and more polluted day by day. Household garbage is disposed of various sources of water. Many people perform their domestic activities like bathing, washing clothes and utensils, etc. in these sources of water.
Also, industrial wastes are discharged into the water, leading to water pollution. Consumption of this polluted water leads to diseases like cholera, typhoid, diarrhea, etc. in human beings. Polluted water also adversely affects aquatic life. Thus, we need to make sure that we do not pollute water.
water pollution essay in English
Domestic activities like bathing, washing clothes and utensils should not be done in rivers, lakes, ponds, etc. Household garbage should not be disposed of in the various sources of water. Also, sewage and industrial wastewater should be treated before discharging into the water.
water is a basic resource that guarantees the life of all living beings on the planet however its scarcity and pollution caused millions of people to have poor access to this much-needed asset humans are the main cause of water pollution which is triggered in many ways by the dumping of industrial wastes due to temperature rise that causes the alteration of water by reducing the oxygen in its composition or due to deforestation which causes sediments and
bacteria to appear under the soil and therefore contaminate groundwater in the same way the pesticides used in agricultural fields filter through underground channels and reach the consumption networks and also as a result of accidental spillage of oil and what are
the main consequences of this firstly the disappearance of biodiversity and aquatic ecosystems also humans are harmed by the alteration in the food chain and by contracting illnesses when drinking or using contaminated water for all this we must ensure water availability its sustainable management and sanitation for all.
how to prevent water pollution essay
water pollution that we examine the many ways the substances mankind throws away have polluted lakes rivers and even the oceans the United Nations estimate that around 10% of the world’s people do not have access to clean drinking water that’s over 700 million people the main problem with is untreated water is that it can carry diseases such as cholera spread through untreated human feces
this is particularly serious in shantytowns near big cities and in refugee camps rivers and streams can also be polluted with diseases from water coming from badly managed rubbish dumps but human sewage is not the only substance that pollutes our water supplies most of the other substances humans allow to escape into streams rivers and the oceans are more a danger to natural ecosystems than to us directly chemical fertilizers are much more soluble in water than organic manure-based fertilizers
so heavy rain can wash them into streams and lakes causing eutrophication the fertilizers caused algae to grow very fast forming a mat on the lake surface this blocks sunlight from the vegetation deeper down which dyes bacteria then feed off the dying vegetation and use up the remaining oxygen supply once the oxygen has gone all animal life dies the lake ecosystem is destroyed if heavy metals such as lead mercury and cadmium get into rivers and lakes many animals will die in Minamata Japan
a polluting mercury fungicide factory was closed in 1968 yet people there have continued to be affected by the mercury poisoning the so-called Minamata disease ever since because the fish caught locally in the bay still have traces of mercury in them.
essay on water pollution
nowadays the use of mercury and cadmium in fungicides has been largely replaced by copper and organic compounds the removal of lead from petrol began in the 70s when it became clear that lead poisoning causing mental defects was caused at least in part by the lead compounds added to petrol to make it burn more smoothly
it has taken 40 years since then for a United Nations global ban on the sale of leaded petrol the last six nations complied in 2013 radioactive waste is normally stored above ground in water tanks waiting for more permanent underground storage where it has to be safe for millions of years there are fears that these underground stores could fail and contaminate watercourses currently small amounts of radioactive material are allowed to be washed out to sea on the basis that it will become so diluted that
it will make no difference to the natural background radioactivity in the oceans following a nuclear disaster like 5 Mile Island in 1979 Chernobyl in 1986 or Fukushima in 2011 watercourses and the oceans can become dangerously polluted with radioactive waste during mining and drilling operations to extract minerals from the earth aquifers which are the underground watercourses can
short essay on water pollution
become polluted huge amounts of plastic thrown away from ships and washed out to sea from rubbish dumps on land have ended up floating in huge islands of waste causing a serious threat to fish seabirds and other marine animals the so-called Great Pacific Garbage Patch is estimated to be half the size of Europe and there are four others coal and oil-fueled power stations have been responsible more
so in the past for causing acid rain which devastated many North European new lakes on acid rain floor on this fossil fuel and nuclear power stations need large amounts of water for condensing the steam which drives their turbines this water is usually cooled on-site in the great cooling towers that dominate the skyline of power stations even so the water will be returned to the river or sea warmer than
before and this can upset the river or sea ecosystems although not material pollution this waste heat is a pollutant so to summarize there are many ways mankind is polluting the rivers lakes and seas perhaps the most serious causing millions to become ill or die is pollution by human souls to learn how we are attempting to purify wastewater.
