Effect of water pollution on animals animals?

Answer 1

Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. When it is unfit for its intended use, water is considered polluted. Two types of water pollutants exist; point source and nonpoint source. Point sources of pollution occur when harmful substances are emitted directly into a body of water. The Exxon Valdez oil spill best illustrates a point source water pollution. A nonpoint source delivers pollutants indirectly through environmental changes. An example of this type of water pollution is when fertilizer from a field is carried into a stream by rain, in the form of run-off

which in turn effects aquatic life. The technology exists for point sources of pollution to be monitored and regulated, although political factors may complicate matters. Nonpoint sources are much more difficult to control. Pollution arising from nonpoint

sources accounts for a majority of the contaminants in streams and lakes.

Clearly, the problems associated with water pollution have the capabilities to disrupt life on our planet to a great extent. Congress has passed laws to try to combat water pollution thus acknowledging the fact that water pollution is, indeed, a seriousissue. But the government alone cannot solve the entire problem. It is ultimately up to us, to be informed, responsible and involved when it comes to the problems we face with our water. We must become familiar with our local water resources and learn about ways for disposing harmful household wastes so they don�t end up in sewage treatment plants that can�t handle them or landfills not designed to receive hazardous materials. In our yards, we must determine whether additional nutrients are needed before fertilizers are applied, and look for alternatives where fertilizers might run off into surface waters. We have to preserve existing trees and plant new trees and shrubs to help prevent soil erosion and promote infiltration of water into the soil. Around our houses, we must keep litter, pet waste, leaves, and grass clippings out of gutters and storm drains. These are

just a few of the many ways in which we, as humans, have the ability to combat water pollution. As we head into the 21st century, awareness and education will most assuredly continue to be the two most important ways to prevent water pollution. If these measures are not taken and water pollution continues, life on earth will suffer severely.

Global environmental collapse is not inevitable. But the developed world must work with the developing world to ensure that new industrialized economies do not add to the world's environmental problems. Politicians must think of sustainable development rather than economic expansion. Conservation strategies have to become more widely accepted, and people must learn that energy use can be dramatically diminished without sacrificing comfort. In short, with the technology that currently

exists, the years of global environmental mistreatment can begin to be reversed.

Answer 2

Water is the livelihood for marine life creatures. Without the water they cannot survive. When the water is polluted it puts the marine life at a risk by making it difficult for them to survive and thrive fully. The pollution is usually toxic and /or deadly for the creatures and if they do survive it can severely alter the functions of their lives. Over 100,000 marine animals die each year due to pollution and over a million sea birds.

AIR POLLUTION, A LETHAL INJECTIONAir pollution affects biodiversity on a great scale. The atmosphere, lithosphere, and hydrosphere are negatively affected by pollution [1]. Air pollution affects lower life forms more than higher life forms. Plants are generally more affected than animals on land, but not in fresh water. A decline in most species due to pollution is evident except for a minority that increase. I will be focussing on plants and how they are affected by air pollution.

Plants constantly take up atmospheric gases i.e. air everyday to sustain their biological processes. Vegetation growing under optimum conditions is most susceptible to air pollution [2]. As air pollution is for the most part man-made, we are the main source of this phenomenon. Pollution can be derived from two kinds of sources namely, stationary and multiple point sources. Stationary point sources include backyard fires (on a small scale) and the burning of a thousand tons of coal each day in coal-fired electrical power plants (on a large scale). Multiple point sources are usually mobile and include automobiles and other vehicles. The vehicles are the most important source of atmospheric pollutants as they release carbon monoxide. This is followed by industrials sources which release sulphur oxides, steam and electric power plants, space heating and lastly refuse burning. Agricultural chemicals also form part of air pollution [3].

The uptake of pollutants depends on the concentration gradient between the ambient air and the absorptive sites within the leaf. It also depends on the conductance of the stomata. The toxic effect of a pollutant may thus be almost directly related to the functioning of the stomata. Stomata openings are related to the physiological activity of the plant in that they regulate gas exchange; correlation exists between the extent of air pollution effects and the degree of opening of the stomata [2]. Pollutant flow may be restricted by the physical structures of leaves or scavenging by competing chemical reactions. However, as conditions change the ambient dose to which plants are exposed does not necessarily reflect actual cellular exposure. The initial flux of gases to the surface is controlled by boundary layer resistance i.e. the amount of gas able to contact the surface. This includes epidermal characteristics and air movement across the leaf.

At slower wind speeds (less that 2m/s), boundary layer thickness decreases as wind speed increases. Thus more pollutant enters the leaf when air is in motion. Pubescence is also important in that leaf hairs provide major areas of impact. Cuticle wax is also important in limiting uptake even if the cuticle is thin. Stomatal resistance is the most critical. Resistance is determined by stomatal number, size, anatomical characteristics for example the degree to which stomata is sunken and the size of the stomatal apperature [4].

Water pollution effects animals because when animals are thirsty, they drink in water full of gas and trash. Also, it's hard for water animals to swim if there is gas to make the water murky and trash to be in their way. Also, an animal could get caught in trash and drown or get a serious wound.

Answer 5

The water evaporates and the fish are left in a dry sandy plane with only puddles of water with a small ammount of sea monkeys in them. Soon after the human race will die out and the majestic unicorn will rule the world and they will make bread out of the remains of eagles

Answer 6

Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels.

Eventually, humans are affected by this process as well. People can get diseases such as hepatitis by eating seafood that has been poisoned.

Answer 7

Pollution can kill fish because if it touches the fish's gill it will cause them to suffer.

Answer 8

water pollution can cause damage to marine life in many ways, one of this is that it can help kill the ocean and kill the animals living in it.
