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.
There are restrictions to deforesting land and there are organizations to help protect the land. One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct.
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.
i) Cultural value:- Wild life is a source of inspiration to poets and artists to compose poems and songs and to make paintings and sculptures. Many animals have contributed to idioms, proverbs and poems. In India the wildlife has a close connection with various religions also. 2.4 Causes of extinction of species:- There are various factors, which have contributed to the extinction of different species of flora and fauna. Some of the factors responsible for extinction of species are as under: a) Destruction of Habitats:- The destruction of the natural habitat is the most serious threat to the wild life.
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.
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.
In time, some species become endangered which can lead to extinction. Being identified as an endangered species involves the likelihood of becoming extinct. The probability of a plant or animal becoming extinct determines whether the plant or animal should remain endangered. Endangered species generate around the world in various regions and climates. Unfortunately, endangered species often involve low numbers of population for a specific species.
In the year 1973, the Endangered Species Act (ESA) was instituted in order to bring attention to the issue of species that are in danger of extinction as well as to provide conservation of species that are endangered or threatened. Currently, there are around 2,245 species that the Endangered Species Act lists as either endangered or threatened throughout the world, many of which are found in the United States ecosystems and a handful that are only found in foreign ecosystems (Ehrlich 12). Because of the considerable number of endangered species, people should be aware of endangered species and help to protect these creatures society, as their unnatural extinction due to our actions and neglect will affect ecosystems and the environment (“Why
The destruction of an ecosystem can have serious effects on the organisms in it such as loss of different species or even their extinction. Therefore, conserving biodiversity is very significant. There are various methods on which biodiversity can be conserved. According to Buchanan (2002), keystone species should be prioritized for conservation. A keystone species is an organism which performs a critical role that greatly affects its community (Power et al., 1996).
It is the global ecological system where all living things interact with each other interdependently. This makes protecting endangered species extra important because the removal of one species can start a chain reaction that will spread through the ecosystem. This means, a lot of times when an animal goes extinct, its absence inevitably affects other living organisms. The food web below shows the importance of a single species and emphasizes the interdependence that exists in an ecosystem. Imagine if the rabbit became extinct?
