Pollution of the worlds oceans and the impact on sea life - Term Paper Example

Overuse of marine resources is based on the growing population at the coast which makes the situation worse and is the main reason for the population problem that has hit marine and marine life (Hofer, 2008). There are various marine pollutants such as sewage and other wastes that are released into the oceans yet there is no facility to counter these. This does not only put at risk marine life but also human and wildlife. Tourism is also affected in the situation thus, low incomes. The pollution could be chemical, physical or biological mainly caused by human activities.

Developing industries are also a big involvement in the situation that has proved to be devastating. In some parts, knowledge of the marine life is limited therefore; they do not realize the dangers that are posed. The harm cause to marine ecosystems is an indirect or direct cause of human activity (Xhelilaj, 2010). When some nutrients are introduced in marines, they cause diseases that affect species all over the ecosystem. For some organisms, these are some of the factors that accelerate their growth.

These pollutants then affect marine habitats adversely so that marine life is in danger. Some of these nutrients interrupt food chains within the ecosystems causing adverse danger to marine life. Construction of marines leads to the destruction of habitual life that is very important to marine life. This destruction then causes depopulation of fish in the ocean. Overfishing worsens the situation everyday. When power plants affect the temperature in oceans because of the heat produced in the process.

This makes these area affected inhospitable and unfit for the marine environment. The species that are evolved there are then in danger because, they cannot survive in such an environment. Targeting particular species is also an environmental problem that leads to decreasing of the population in the marines. Many chemicals end up in the destruction of marine life. They are taken up by planktons and benthos which are animals that are feeders within the ocean. This therefore destructs the life in these environments.

This means that food chains will be interrupted. These chemicals introduce toxins to the marine life thus posing a danger through the feeding system. Pesticides also become quickly incorporated into food that is taken by marine life. This slowly poisons these animals because, these chemicals are slowly absorbed into the food webs within which they feed. Once in the food, they can cause mutations or even diseases that are dangerous to marine life. This is harmful to human life as well as to marine life thus affecting the whole food web.

Toxic metals also introduced can cause biochemistry, unknown change to tissue matter or even affect the reproduction of these animals. Ships are also a source of pollution in marine life. This comes along when they spill oil in oceans thus causing devastating effects. They are toxic to, marine life and the effect could last a long period because, oils like crude oil are hard to clean (Katsioloudis, 2010). This means that the oil will last in the ocean for quite some time. Oil is also dark and opaque therefore, oil is blocks plants from sunlight.

This denies them the ability to synthesize through population. Thick oil also sticks to some parts of sea animals thus making it difficult for them to perform some function. Sea birds are the most affected because, oil sticks to their wings which makes it
