Due to the increasing demand for these medicines, the number of plant and animal species that are being used are at risk of endangerment and extinction. Traditional Chinese Medicine uses roughly 1,000 plant species and 36 animal species, such as the tiger, rhinoceros, sea horse, black bear and musk deer; the rhino, tiger and sea horse in which are threatened and endangered. Pollution through water, air and the ground, for example: acid rain, water pollution and oil spills have all proved very harmful for numerous species of birds and fish.
Introduction More and more species are becoming endangered every day and around 6000 are already endangered. Species endangerment is causing major issues, in our ecosystems and biosphere, as well as many other big problems that not many people realize and/or do anything to change. Even though there are many causes for extinction, the impact of habitat loss is the major reason that animals are becoming endangered and it is all our fault, the habitats being harvested for human consumption. Why Does Extinction Matter? Merriam-Webster defines extinction as the state or situation that results when something such as a plant or animal species has died out completely.
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.
The roots of these problems all stem from the massive negative ecological impact these organisms are having on the environment (CBD, 2009). For all animal extinctions where the cause is known since the 1600’s, invasive alien species have been a contributing factor 40% of the time (CBD, 2006); the second most contributing factor to extinctions after loss of habitat (GC, 2013). By eliminating native species through competition for resources, predation, and transmittal of disease, invasive species continue to reduce biodiversity in almost all ecosystems around the world (CBD, 2009). In the future, this problem may worsen, and if no action is taken, could lead to a cascading ecological problem so large that whole communities or even ecosystems could collapse.

Once again, humans seem to be the root cause of large amounts of deaths that have the potential of leading to a decrease in the population of a species. The human population continues to fail to recognize that they are overusing animal resources and mistreating these animals. If this overuse and poor treatment does not change, the population of thousands of species could be at risk and many ecosystems and important industries will be put in danger. More focus needs to be put on the different ecosystems and animal species, endangered or still highly populated, in order to keep them alive and well.
Moreover, the production of charcoal and over-grazing is considered to be causes of extinction in Himalaya (WWF, 2011a).Many Himalayans depend on farm animals for their living but do not have enough food for them; as a result, large numbers of grazers are found in the forests destroying the future of the forest (WWF, 2011a). In addition, WWF (2011a) claimed that poaching and illegal trade in wildlife is one of the main causes of extinction to the endemic species in the region. Because of high commercial value, some critically endangered species such as tiger and rhino are poached. Other species like deer are poached for their meat (WWF, 2011a). Similarly, fish poaching is considered to be a threat on the biodiversity because the poachers contaminate the river when they use nets and poison to get the fish (WWF, 2011a).
Today we have so many new things like advanced technology but yet we can’t understand the simplicity of animals? If we were to ban the use of animals for sports and entertainment we would be against the will of our past generations. Animals have been in our lives for as long as we can remember so why should it be okay to abandon them now? Many animal establishment strive off animal entertainment. Places like SeaWorld and the Animals Kingdom bring millions of dollars in and also offer thousands of job opportunities for people.
Combining Environmental Groups in Order to Preserve Wildlife Environmental issues have been a problem all over the world. Some species are constantly being declared endangered and on the verge of extinction. A group of concerned people join together to raise funds in order to improve the habitat or produce more of the endangered species. These organizations have proved to be successful. Many have even removed plants and animals from the long list of endangered species.
There is very little that can be done to stop the corridor from being cut down, putting Sumatran tigers at risk or any other species that use the corridor as a breeding place or a habitat. Impact on Humans and other Organisms Similar to solution 1, the corridor may help to maintain and increase the Sumatran tiger population with concern that this will result in a decrease in prey species population because more tigers eat more prey. However, the corridor provides habitat for these prey species allowing them to bred and increase in number similarly whilst increasing biodiversity which outweighs the disadvantage. Alternatively, this may provide risk to local people and plantations e.g. by taking up land which could produce money for local economy.
The northern white rhinoceros, nightingale reed-warbler and Hawaiian cow represent only a fraction of the many species which listed on the IUCN list of threatened species. Moreover, many thousands of species have already become extinct across the world over the last 100 years. The impact of extinction on the biological world is unprecedented and it creates a ripple effect which impacts all aspects of our lives. This current rate of extinction is out of our scope, our resources are limited and the time available is inadequate. On top of that, ecologists can’t even successfully estimate the number of organisms going extinct!
