And it is also because the primary cause of extinction is the human kind that is abusing the nature. Causes of extinction, there is no single factor that causes extinction. Some of the species are gradually decreased because of their thousands of years existence is they are not competed with the other species. And the most common cause of extinction is the degradation and the loss of habitat. In New Zealand the most common threat is the introduction of alien animals to their environment.
Supporters of de-extinction reason that by studying resurrected species first hand, scientists can learn the underlying causes of extinction and the role that humans played in the destruction of both the extinct species and their natural habitats. The idea is that researchers will be able to develop countermeasures that will restore the earth’s ecosystem to its original state.This counter argument is not valid, however, for two important reasons. According to Strayer, “First because we’ve been changing our world so rapidly, a de-extinguished species won’t be restored to its former ecosystem, but to a different, sometimes radically different ecosystem” (Strayer). This statement illustrates that the damage caused by humans may very likely have cumulative effects that have occured over many centuries; therefore, it is not reasonable to assume that all of these cumulative effects can be repaired by bringing back one species at a time. It would not be possible to recreate the exact circumstances of the earth’s ecosystems at a specific point in time because of differences in the role of species in the environment, the condition of the environment itself, and the present and future impacts of humans.
In conclusion, the combustion of fossil fuels and deforestation are the main sources that cause greenhouse effect. The suitable measure should be taken to minimize the consequences of human activities on climate and environment, especially resolving the problem of greenhouse
Evolution can be the cause of extinction. Tis can be by overpopulation which is when we have a very powerful group kill out an organism. Also, less land for a species can cause the rate of deaths to be greater than the births. Then, if the new species is to strong it can mess up the entire food chain. This proves that evolution may cause new species but, it isn’t always good.
People could be exploiting animals for solely human purposes, and may cause individuals of the de-extinct species harm. Their habitats and food sources have changed, so their roles in ecosystems could be, too. De-extinction can distract other other science fields, such as medical research (D-Brief,
When an animal becomes endangered, than people have no idea how long these animals have till they will be lost forever (Endangered Species: Facts). The reason why species become endangered is because their habitat is lost, animals have competition when it comes to eating, and pollution in our economy (Endangered Species: Facts). If people tried to reduce the pollution and did not take land that did not belong to them, than some animals would not be endangered to this day (Endangered Species: Facts). “As of May 2017, the U.S. FIsh and Wildlife Service lists 2,392 animals as endangered worldwide” (Endangered Species: Facts).
Humans are producing a negative impact on the environment by polluting the air, along with over hunting. Humans are producing a negative impact on the environment by polluting the air, which can long-term injure the Earth and can construct major impacts on animals’ lives. Burning fossil fuels, deforestation, and nuclear accidents are all types of Human triggered air pollution. Burning fossil fuels is is the largest contributor to global warming. Global warming produces rising temperatures, dissimilar precipitation rates, arctic glaciers and ice to melt, stronger hurricanes, and the sea level to rise.
In prehistoric times, natural disasters and competition with other species were the main causes. In historic times, overexploitation and exotic species introductions have caused many extinctions. Today, the main problems facing wildlife are destruction of habitat and pollution. All of these threats have put serious impacts on the diversity of species on Earth. Biodiversity loss is driven by local, global factors and human activities, so responses are also needed at all scales.
We all know that the world ecosystem is a delicate balance, we also know that everything would fall apart if something as major as all animal kind went extinct. Cause it won’t just affect the animal chain but also affect the human race. Some plant and insect would be over populate and eventually human kind would be in more trouble other than animal extinct. Example animals are used by some plants to disperse seeds, some animals can eat other plant-eating animals, bees and other insects help pollinate flowers, earthworms aerate the soil so that the roots of plants can better obtain oxygen. One of the example is the remora
Within the next 50 years, according to the study of Nature, 25 percent of the land animals will become extinct. The leading cause of endangered species is habitat loss, which are caused by humans cutting down trees and using pesticides in the fields. Habitats are being destroyed due to humans using them for the use of agriculture and buildings. However, most humans do not know when they destroy habitats they are affected too, or the causes of endangerment and how they can help save endangered animals. The International Union for Conservation of Nature and Natural Resources (IUCN) Red List consist of a total of nine categories for the threat level of species.
