Recommended: Biological importance of water
Water being the most important and valuable resource available to us on earth, covering most of the earth surface. Water is the essence of life & is required for life by the humans & the environment. With a growing population of earth, water may be misused or taken for granted by most of us which leads us to water pollution, which not only does harm our water bodies & natural environment, but eventually our drinking water & our human health. In todays world, we have changed the way our industries work, our Agricultural processes & basically everything that works. We as a society want everything to be faster, efficient & making more profit, whilst harming the environment. Industrial & Agricultural work involve the use of many different chemicals …show more content…
With chemical water pollution being our focus in this essay, it is the most dangerous form of water pollution in our water bodies. They are usually colourless, odourless, & tasteless. Water pollution may also affect the marine environment & food chain, affecting many species in a catastrophic manner. With so many impacts of water pollutions, which will be discussed in great details below, we need to make a change now to the way of our living, work, & how our industries & agricultural systems work. This essay will focus on chemical pollution in great detail, as it is the main biggest pollutant of our water. Water Pollution is an ongoing problem that has serious affects; it’s impacts grow everyday in our lakes, oceans, rivers and other bodies of water. Chemical water pollution affects us all, the environment, water, us humans & all natural species. We all together as a community need to adapt & prevent the water & earth from further pollution & make this earth & its environment a better place for the future generations for them to live a healthy life with clean fresh water for them to live on. The impacts of water pollution can be seen globally as well as Canada …show more content…
Economically treating water is not an easy and cheap thing to do, especially as the population grows the deand grows. When water pollution occurs it damages the economy & can be expensive to treat & prevent from contamination. Some wastes are too big enough to break down and so are accumulated in the earth’s water & eventually makes it way to the earth’s ocean. The pollution can be prevented in a number of ways by stopping the pollutants by contaminating the nearby waters such as the use of biological filters, chemical additives & sand filters. We are focusing on chemical water pollution so in that case we would be looking to use chemical additives. These methods are costly to maintain but are cheaper when compared to the cost of the clean up of pollution which depends on various factors such as; the location, the size of the contamination & the type of pollutant. Oil spills are the biggest troublesome chemical pollution on water. Many cases of oil spills have occured in Canada & big ones such as the Exxon Valdez which occured just off the coast of Alaska. There are many ways to clean up an oil spill but is very costly up to 3.8 Billion dollars!! The method of an oil spill clean up depends on many factors such as the size of spill, location etc but the main ways of lean up are oil booms, sorbents, dispenser, skimming, burning &
Humans need water. In a world that is overpopulated, we use a lot of water and other natural resources. Currently, in our world, clean water is getting scarce. Recently, for example, Flint, Michigan, had a water crisis. In early 2016, the water was discovered to be tainted with lead and other toxins. Long before that, the Michigan Department of Health and Human Services, and Governor Rick Snyder along with his council, knew about the lead, but to save money for the city of Flint in early 2014 Snyder had changed the city’s water source to the Flint River which had corroded pipes, causing people of all ages to be sick from the high amounts of lead
The industrialization of Canada is severely affecting the nations lakes, streams, and rivers. If something is not done to improve the situation it is going to have some severe environmental problems in its future. The following essay will be looking at the factors that cause pollution, and the effect that pollution has on the environment of Canada. It will also explore some of the methods used to treat and clean-up wastewater, and oil spills.
Pollution comes in many forms. In the ocean we dump a variety of substances, including human wastes, chemicals from fertilizers, oil, and trash such as plastic which all contribute to the growing issue of our ocean pollution. In addition to, our usable waters are finite. More than 97.5 percent of the water on this planet is undrinkable salt water; the remaining 2.5 percent has two-thirds of the usable fresh water locked up in glaciers, snow, and permafrost. Of the one-third of freshwater that is available for human use, 20 percent is used for industrial use. (“Water Pollution”) “In effect, water pollution reduces the volume of water available for use by human and other populations.” (Robin Clarke, Jannet King) Knowing that there are approximately 7.2 billion people and growing on this planet with only 0.83 percent of available for our use wouldn’t you want to do everything possible to help put an end to water pollution? (worldometers)
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Water pollution can affect a farmer’s ability to grow nutritious crops for personal and human consumption. Water seems to be an abundant resource, but drinkable water is becoming very limited. Unfortunately, this precious resource is easily contaminated by agricultural runoff, mining activities, waste treatment plants and improperly disposed-of industrial waste (Wieman, 2014, para.3). Water is a valuable resource that is used to fulfill human needs and to replenish nature which provides food and nourishment for the human race. As God commanded in Genesis 1, Christians are to be caretakers of the environment.
Water is on of the most precious natural resources that exist on our planet. “It is delivered from the atmosphere in the form of rain, snow, hail, fog, and condensation and returns to the atmosphere by evaporation and transpiration” (Hannigan 1969). Although many of us love activities that have to do with water, we disregard it and pollute out rivers, lakes and oceans. Slowly but surely we are going to harm out planet till no return. Protecting and conserving nature will secure a better future. 71% of earth is covered with oceans. Sounds like a lot right? Imagine ...
People don’t appreciated the many advantages that comes with having clean potable water to use, taking it for granted. A lot of clean useful water is wasted by humans all the time that people don’t care about saving water because they have easy access to it. Clean and safe drinkable water resources are getting scarce as the population grows. The world is facing many problems, but the most important needed to survive, is water. Water is getting low in many countries, therefore habitants are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages; meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands. Water shortage affects the agricultural sector, so as a consequence the price for production
Wastewater is simply water than has been used from industries, domestic and ground water run-off. It usually contains various pollutants, depending on what the water was used for. The wastewater is treated to improve and purify the water by either removing some or all of the pollutants. After treatment, the water is fit for reuse and discharge back to the environment. The act of making the wastewater fit for reuse is recycling. Not only does reusing waste water benefit humans economically, it also assists in sustaining the quality of the environment.
The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
Freshwater in the world makes up only a small portion of the water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only 1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes.
Water pollution is also a major thing in the world because almost 60% of it is fishes. It occurs due to several factors; the industrial waste dumped into the rivers and other water body’s cause am imbalance in the water leading to its severe contamination and deaths. And the infamous Global warming is the emission of greenhouse gases particularly CO2 is leading to global warming.
The key word is “drinking” water, while the world is made of 71% water, not all of it is suitable “drinking” water. For water to be considered drinkable, it must be devoid of all harmful agents and be safe to not only drink, but also prepare food with as well. That water only makes up 3% of the world’s water. In addition to that only 1% of the world’s water is available to us because the other 2% is frozen in glaciers. To make matters worse, we even pollute the water we have available to us. After the industrial revolution, the human race lost the connection with the environment and broke the balance between maintaining the planet and developing technology. Water pollution doesn’t reduce the amount of water in the world, but rather reduces it efficiency. Water is still being cleaned and processed into drink...
Are you aware of the detrimental impacts that we have had on our environment? Every second, the Earth is being polluted by poisonous gases, waste products and due to human activities, the world’s climate is dramatically changing. In other words, these impacts do not only harm our environment but also our health. It has been scientifically proven that air pollution causes respiratory diseases and cancer, due to the inhalation of all the harmful chemicals. Water pollution can also lead to typhoid, diarrheal diseases and other waterborne disease, due to the intake of bacteria and parasites. Many people have died due to these health-related illnesses. So why are we still living in this awful condition? Air sustains us and water is a basic necessity, so we should do what we can to prevent pollution. In short, we should protect our environment to ensure a healthy life a...
Water is an important part in the world, it’s essential for life, so why pollute it? Chemical and plastic pollution harm the environment and marine life. There are many effects in water pollution and there are many different types of water pollution.
The current world population of approximately 5.9 Billion will double in the next forty -ninety years. To further compound the water shortages, human consumption of water is rising twice as fast as the population. The exponential population growth has a severe effect on the amount of water being used and the amount of pollutants that go back into it. Take for example the problems that people in California are having with water and trying to get it. California's current water use is unsustainable. In many areas, ground water is being used at a rate that exceeds the rate of natural replenishment. Fish and wildlife species are being destroyed by withdrawal of water, as well as by development. Official projections are that water demand will exceed available supplies in the year 2020 (Simon 18).
