A single water drop traveling from any river to any ocean is influenced with more than one hundred toxic chemicals and thousands of industrial pollutants. This is what people call water pollution, occurring in any state, country or continent. Unfortunately, throughout the centuries, water pollution has been an ongoing problem, mainly caused by the release of industrial toxins and chemicals. People around the world believe that plastic and metal make up the vast majority of this issue, but as years have come and gone, the quantity of chemicals released by small and large facilities are now the leading cause of water pollution. Although industries need to release waste somewhere, they should avoid putting it in waterways because it impacts the …show more content…
Not many know that eutrophication is an over abundance of nutrients in a water body induced by nitrogen and phosphate levels escalating from chemicals and pesticides. Eutrophication produces algae to the extent of depleting the water of oxygen, killing off all marine life by suffocation. There are many possible reasons why nitrogen and phosphate levels rise, but they have mainly been “associated with discharge of wastewater treatment works effluent, urban run-off . . . mining and agricultural activity” (Griffin 2). Effluent is liquid waste discharged into river or oceans. Urban run-off is rainwater that travels to nearby communities and cause flooding, but mainly water pollution. Mining and agricultural activity both release pesticides and chemicals illegally, or accidentally, causing water pollution. Notice the common association: they all cause water pollution. Rarely anybody knows that enough water pollution can change the amount of nutrition in waters as quick as lightning, suffocating any surrounding organisms. Chemicals have a composition that botches the levels of nutrition in water, mainly caused by “...agriculture... in this regard, because increased fertilizer use and intensive livestock farming increase nutrient inputs” (Ilić and Panjan 3). Manure and strong fertilizers have certain compounds found inside that are directly discharged from livestock farms, altering the physical and biological aspects of water. Even though nutrition is found in water at low levels, a high enough contamination of pesticides has a major of affect on the survival rate of marine life. The authors expresses that when eutrophication occurs, algae grows and suffocates the fish, leaving the survival rate at low
During the summers the oxygen content atop the water normally has a salinity level consistent with “more than 8 milligrams per liter”; but when oxygen content drops down to “less than 2 milligrams per liter” the water is then known to be in hypoxic state (CENR, 2000; USGS, 2006). Hypoxia is the result of oxygen levels decreasing to the point where aquatic organisms can no longer survive in the water column. Organisms such as fish, shrimps, and crabs are capable to evacuate the area but the fauna that cannot move either become stress and/or die. Due to this, many call the hypoxia zone the “dead zone” (Overview, 2008; USGS, 2006).
Whether we want to believe it or not water pollution is one of the world’s l...
The agriculture industries have affected the marine life due to eutrophication. Eutrophication occurs when human activity water because of the chemicals, nitrogen and phosphorus which run off into the water. Eutrophication results in algal bloom. An algal bloom forms when lots of nitrogen and phosphorus are set inside a body of water which results in an excess amount of algae in lakes, oceans, or streams. The waters can not take in a lot of algae because in can affect the habitat of the animals. It can also affect the population of the sea animals.
Ocean Pollution is a serious issue in today's global politics. The delicate balance of Earth's ecosystem is put in jeopardy when the ocean is not clean. Problem evolving from ocean pollution directly harm marine life and indirectly affect human health and the Earth's many valuable resources. Ocean Pollution is a Broad term that encpompasses any and all foregin matter that directly or indirectly makes its way into the ocean. This includes everything from the extreme: oil spills, Toxic Waste dumping and industrial dumping-- to the small scael: human activities and basic carelessness. Because the oceans and all other water bodies are invariably, somehow connected, and because they account for 3/4 of the Earth's surface, they are an ideal method of transportation for pollution, allowing the rapid spread of seemingly far away toxins into a river near you! It is increasingly important that we educate ourselves as to what, exactly, ocean pollution is, so that we can identify the causes at their source and take action in small and large ways, and hopefully, prevent this terrible form of pollution from getting any worse than it is today.
Our oceans take a large beating every day by the extremely large amount of pollution humans produce. Our society easily dumps their waste into the oceans to dispose of the excessive amount of garbage, sewage, and chemicals, but this small and simple solution is creating an even bigger problem. The way humans dispose of their wastes is causing the death of our beloved marine life. Not only are we killing off our animals, our food source, and our resources, we are also minimizing our usable water. By having a better understanding of the problem on the severe dumping, it will be easier to find ways to help minimize the pollution that is going into the ocean.
Water pollution has had devastating effects on the environment, which include irreversible effects to the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousand of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever; unless there is a balance. We must protect the resources we have in order for them to last into the next generation. Every time we throw away a plastic bottle, drive our cars, and even burn those millions of fossil fuels to operate all those huge factories, there is a chance it will pollute the ocean and eventually effect the way we live. There should be stricter laws regulating human pollution, in order to protect our oceans ecosystem.
Nutrients are substances that all living organisms need for growth and reproduction. Two major nutrients which are nitrogen and phosphorus occur naturally in water, soil and air. Nutrients are present in animal and human waste and chemical fertilizer. But, if the nutrients are in excessive amount, it will tend to cause nutrients pollution towards the environment. The over-development in agriculture and industrial area had accelerated the rate at which the wastewater containing excessive nutrients (mainly nitrogen and phosphorus) entering ecosystem without proper controlling system. There are many primary sources of nutrient pollution that will eventually create the eutrophication effect.
One of the pollutants companies cause is water pollution. Water pollution is the impurity of water by chemicals, pathogens and other elements that make water undrinkable. Companies such as Industrial plants are producing more than half of the united states water pollution because when their water sources take away all of the industrial wastes from the manufacturing facilities, they often carry the wastes into waterways and streams which then spread the pollutants into a much bigger area and flow into oceans and rivers. ” More than 40 percent of America’s lakes, rivers, and estuaries were too polluted for drinkin...
“For many years the rivers flowing into the Mediterranean sea and the sea itself were seen as convenient dumping grounds for domestic and industrial waste.” (Chiras,2015). Many people polluted the environment without even realizing the effect they were having. This created major problems later on for future generations. “Pollution also enter surface waters from the air and surrounding lakes.”
In recent years, increasing awareness of water pollution and its far reaching effects has prompted concerted efforts towards pollution abatement. There are so many pollutants (bacteria, heavy metals, chemical, etc.) found in water. If we do not find solutions to clean our water, our marine animals will die.
Can you imagine a world where clean water does not exist anymore? Can you imagine going to your kitchen and seeing black water instead of clear coming out of the faucet? Would you still go to the park if the rivers, lakes, and oceans would turn the color of oil and pollution? Would you still take your kids to see the fish and other living species if they were no longer living and floating belly up? How much would you pay to get the clean rivers, lakes, and oceans back? How much would it cost to get the living organisms living again in the rivers, lakes, and oceans? Maybe it is hard to imagine this world today because it is not as bad, water is not black, and living organisms don’t float bellies up when you walk by, but if we don’t think of the long run consequences of our polluting way of life today this horrible world won’t be so hard to imagine. Water covers about 70% of the Earth’s surface. It is the most valuable natural resource we have. For the most part all living organism require water to live, without water we would not exist. Water pollution is a very huge problem. By polluting our rivers, lakes, and oceans we are harming our planet. Organisms are dying at a very disturbing rate. Our drinking water has become greatly affected as well. There are a variety of causes of pollution they include sewage, fertilizers, wash off deposits, pathogens, petroleum, radioactive substances, heat, and other. The enormous accidental petroleum spills are an important cause of pollution especially along shore lines. Off-shore drilling operations contribute to the pollution pool. Certain statistical estimates state that for every million tons of oil transported one ton gets spilled. This paper will concentrate on oil s...
toxic waste causes many sea life deaths, and chemicals can leave long-lasting, damaging effects on food chains. The first cause and effect that pollution has on ocean life is that dumping waste or littering cause fish growth to deteriorate. There is a huge amount of waste in the oceans today and this hasn’t had a great effect on the sea life. In passage one, the author claims that, “Ballast water tends to proliferate and transfer organisms that debilitate the growth of naturally occurring fishes in a particular oceanic area.”
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
