Biodiversity Loss and Extinction

We are looking into how the reason why plants and animals are endangered relates to human activity. There are four reasons in the following passage. First, some species are endangered because of the destruction or the degradation of their habitat. As is known to all that most species are adapted to a specific environment, if they lose the habitat they got used to, they cannot survive. Human beings want to develop enough residential area to live in, industrial area to work in as well as some agricultural places to grow crops in.

As houses and roads are constructed, forest are cut down and cleared; consequently eliminating the natural habitats of wildlife. This causes animals to migrate to new areas and seek refuge. Under certain, harsh circumstances, the animal may become extinct. Due to the propagation of the human species, greater and greater amounts of land are taken away from wildlife. Eventually all land will be commercialized for human needs, thus leaving wildlife lost in the shuffle.

Accepting the doctrine of Animal Rights can result in the extinction of native animals, and also cause adverse effects on the environment. Another consequence of accepting the doctrine of Animal Rights is that humans will no longer be able to control foreign predators (pests) via traps, hunting, fishing and poisons. Many foreign animals have been introduced to different ecosystems over the course of history, and is very likely to have caused many extinctions of indigenous species. This occurs because they compete with native animals for habitat and food, and sometimes introduce new diseases. Maintaining the indigenous species and thus biodiversity is important because animals depend on each other in a food web, and an extinction in one can result in many more following.

We as people are some of many reasons animals become endangered. Natural habitats are ruined because of human activities such as construction work, the extension of agricultural work, destruction of forests, etc. which results in bad effects in animal’s habitat, food cycle, reproduction progress and climate. They don’t have any further vegetation which causes them to Land for cultivation is extended due to the population growth. Various types of development and construction work are continuing.

Animals can become endangered for many different reasons, Scientists and Researchers believes that the Habitat loss is the main cause. Pollution, overhunting and overfishing can also affect the population. In other words, the human activities are the biggest problems. Food chain and diseases disruption are involved in this issue, however, many different kind of issues can put the life of the creatures at risk. Due to human expansions, many animals are on their way to extinction, it’s our job as human to protect these species from extinction.

According to Sonia Madaan, states that “the environmental degradation affects are human health, poverty, and loss of biodiversity etc...” (3) What we did to the environment is giving us the effects of it to make us realize and learn something from it, but we actually close our eyes. To summarize, the effects of environmental degradation is affecting us not only animals but also us as a human being. It has both negative impact to human and

When deforestation happens, these animals have gradually fewer areas in which they can live. Once these areas are destroyed, the species become extinct. Animals promote in balancing our ecosystem, food chain and perform as food for us. Therefore, it is really a disgrace for us to destroy their habitat. Deforestation destroys their natural homes and habitat forcing them to relocate, sometimes they try to move into inhabited area looking for food or shelter a... ... middle of paper ... ...s, also to release the water gradually into rivers.

Why We Need Conservation Humans have destroyed animals and vegetation by clearing land and “developing” it into land for farming, housing, factories, roads, and for other uses than what it was intended for. Domesticating animals and producing crops in mass production has made a major impact on our natural resources. Over utilizing natural resources has disturbed the ecological balance of the environment leading to the extinction of species, polluting of water and air, and interrupting the natural food chain (Sanderson, 2002).

These reasons are either natural or man-made. Some of the identified reasons are stated below : • Habitat Destruction - the residence of a species can be destroyed by any natural calamity or any inconsiderate act of mankind. This can cause the species leave that area or die. • Overexploitation of Resources - excessive consumpsion of a species through capturing, hunting, fishing or logging can cause extinction of that species. • Pollution - pollutions cause physical, chemical and biological changes in an ecosystem.

Background Info When a species becomes endangered, it means that the species is being threatened with extinction. Since the beginning of time, numerous species have gone extinct due to naturally changing physical and biological conditions. Human factors such as pollution, commercial overexploitation, poaching and deforestation have all contributed to the increase in the rate of extinction of animal species. It is important to preserve endangered species since their extinction leads to an inequity in the food chain, which could lead to an imbalance in population. The extinction of animal species increases the amount of carbon dioxide in the air, hence worsening the greenhouse effect.
