The Effects Of Water Pollution On Aquatic Environments

When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source. In some cases even killing an entire species.

Rain washes the pesticides that are used in our Australians households and then become run-off in drains and sewers. They then make their way into nearby water bodies, wether that be creeks, rivers or even oceans and settle within the soil by sticking to small particles, including tiny living organisms like phytoplankton (M. Barwick, 2003, pp. 471-502). Small fish consume these tiny organisms, which may then be eaten by a larger organism and this continues until the top order consumer is reached. The concentration that first began in the phytoplankton and has multiplied sufficiently as it moves along the food chain. The amount of the pesticide has reached a highly toxic level in the top order predator, whether that is birds or even humans. As a result of the biomagnification of pesticides and other chemical the marine environment and the organisms that live within it are heavily affected. The build up of heavy metals, for example, it interferes with the formation of red blood cells, creates liver and kidney implications and forms reproductive defects in many organisms. This hinders an organism’s ability to survive and reproduce and can create a decline in species

Water is probably the most important resource we as people have. Humans can survive without food for several weeks, but without water we would die in less than a week. On a slightly less dramatic note, millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water, we use it as a dumping ground for all sorts of waste, and do very little to protect the water supplies we have.

By using these chemical pesticides on the plants, it causes dissolved oxygen depletion in the water, phytotoxicity to the plants, and poisons the animals (Environmental Effects of Pesticides). From the greediness of crop cultivation, millions of species of fish will disappear. These pesticides do not only get into the ocean by spraying it, they get into the ocean when small particles fly over from the drift of the wind. This is especially common at beaches where people spray chemicals on the grasses nearby to prevent other people from being bitten by insects. Not only do pesticides affect the oceans, but the plants as well. These pesticides cause phytotoxicity refers to plant injury. By using these chemical pesticides, it damages the plants, especially those genetically similar to weeds. They can progressively result in mutations little by little until eventually there will be a period of time where the plants now will be very different. Even though this is what is happening now, Hawthorne, an author from 200 years ago, also thought that scientists were being evil. In “Rappaccini’s Daughter,” when it states “Dost thou deem it misery to be endowed with marvellous gifts, which no power nor strength could avail an enemy?...Wouldst thou, then, have preferred the

Water pollution impacts how humans and other living organisms live their life. Most common way humans are effected by water pollution is through diseases while drinking the water. Scientists have found over “five hundred different types of diseases” that can affect humans. (Book). These diseases get into the water streams by human and animal wastes. The diseases in the water can often lead to death for humans. Recent research has shown that that each year

Water pollution is defined as “a change in the chemical, physical and biological health of a waterway due to human activity” (1). Over the past 50 years, pollution in the Great Lakes has been a rising concern. Pollution in the Great Lakes includes the disposal of sewage, heavy metals, invasive species, and pesticides that come from factory dumping, runoff of agriculture, nautical transportation, and air pollution. According to an article published by the US Department of Commerce, roughly 40 million people depend on the Great Lakes for drinking water, sport, power (electricity), and transportation (McCartney). The negative consequences of water pollution include, but are not limited to, the killing off of vital organisms, an increase in birth defects, infertility, malfunctioning nervous systems, and learning disabilities (McCartney).

According Oraclethinkquest, "Water pollution has the potential to have a harmful effect on all living things including plants and animal species. Chemicals, radioactive waste, industrial waste in the water can affect species and their development. There is no

When we talk about how water is being polluted we just justify ourselves saying that there is a lot of water in this world and that a little bit of it getting damaged doesn’t matter at all. To understand the consequences of water pollution we first have to know what water pollution is and how it happens. Water pollution is the contamination of water bodies like lakes, rivers and oceans. This form of environmental degradation occurs “when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds” (“Wikipedia”). Chemical waste from factories is sometimes dumped into rivers and lakes. These chemical

Organisms without back bones are Macro Invertebrate species (Seminole.Wateratlas.Usf.Edu ,2012) . These organisms are small but can be seen without a magnifying glass (Waitakere.Govt.Nz , 2002) . Size ranges from 3-20mm long (Waitakere.Govt.Nz , 2002) .Insects, crustaceans, mollusks, worms, leeches, and anemones are classified a Macro invertebrate species (Waitakere.Govt.Nz , 2002). Streams that are free from pollution will contain a variety of these animals. Streams that have higher pollution levels will less of these animals.

When looking at the ocean pollution caused by people it impacts animals and ourselves as humans. For many years, the unregulated dumping of chemicals, toxins and other waste directly into lakes, rivers, streams and oceans triggered disease and other risks to humans and wildlife(Calhoun 89). This can affect

Water pollution has had devastating effects on the environment, which include irreversible effects to the ocean's ecosystem, health problems and abnormal conditions.

There are many different kinds of pollution that affects living things such as; Land, Air and Water pollution. However one of the vital pollutions is Water pollution that causes damage to human’s health. Water pollution is one of the main reasons why there is declination of freshwater resources. Water pollution has a massive effect on living things. There are many causes of water pollution and a few of them are; marine dumping, sewage waste and oil spill. They are many reasons to what causes water pollution such as, littering on lakes and rivers, flushing down oil and unbreakable items.The impact that water pollution has caused on the society is improper sanitation, water-borne diseases and scarcity of animals. The ethical dilemma of water pollution is that marine dumping cannot be fully avoided which in return could cause land and air pollution. Thus every nation should work on ways to reduce water pollution.

Over two thirds of Earth 's surface is covered by water; less than a third is taken up by land. As Earth 's population continues to grow, people are putting ever-increasing pressure on the planet 's water resources(Chris 1).Water pollution affects the entire biosphere – plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biological communities(WIKI 1).The three acts which causes water pollution are when garbage is dumped into oceans,and causing oil spills while transporting crude oils,industrial waste dumped into oceans.

Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

70 % of our Earth surface is covered by water and almost 60% of the human body contain water for nutrient transportation. The unique characteristic of water is water molecule is the only substance in this Earth that exist in all three physical states of matter which are solid, liquid and gas. All human beings need water to survive. The national development over the years cause the rate of water pollution increased. According to Gebre & Rooijen (2009) water pollution can be considered as a sign that derives from economic growth and is a common phenomenon in urbanized cities in developing countries. In general, there are three main issues that related to water pollution which are the causes, effects and the way to decrease this problem.
