People. Society. Humans as a race pollute the environment, hunt animals simply for their parts, fish way more than humans will ever need just for the sake of money, introduce new species to new places for our own gain, and even purposefully destroy entire regions just for human expansion. And its starting to take its toll. While it is true that nature is constantly in flux and certain species come and go, humans are causing more species to disappear in the past few hundred years then nature has ever caused since the age of the dinosaurs, and therefore it is up to humans to repair the damage caused, be it cleaning the environment and habitats of these creatures, or taking more direct action to protect and preserve the species that are on the brink of extinction.
It is worldwide knowkn that no creature exists in isolation, ecosystems are dilicate arrangements where plants and animals all depends each other for survival. The removal of a single species can disrupt the balance, conceivably set off chain reaction affecting others by breaking the food chain and altering the habitat where they live. Many animals and plants become endangered or extinct each year. Recently, however, the rate of them dying out increased dramatically. It is estimated that 27,000 species become extinct each year, about 3 an hour.
Endangered Species Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals, birds, reptiles, amphibians, and (many people donÕt consider them) plants. CAUSES OF EXTINCTION Millions of years before humans, extinction of living things was linked to geological and climate, the effects of which were translated into major alternation of the environment. Environmental change is still the primary cause of the extinction of animals, but now the changes are greatly accelerated by humans activity.
The changes on earth will always impact different species no matter where the species occupies. The changes on earth have led to many species becoming endangered. Endangered species continue to increase and without help, earth’s species will become distinct. Many factors contribute to why animals become endangered such as environmental changes, lack of resources, new species, and the evolution most species encounter throughout
 People feel that extinction is very sad, and try to protect life-forms on the brink of extinction by naming them "endangered species" and being nice to them.  Each living organism which humans force into extinction is a tragedy for nature.  Over fishing or excessive hunting by humans can reduce the populations of certain organisms on Earth.  Animals are hunted for their fur, meat or other valuable parts of their bodies. http://www.galactic-guide.com/articles/2R84.html http://www.saburchill.com/hfns02/chapters/chap019.html 1. lost of habitat  Sometimes human activities destroy the habitats of living organisms.
People often say "Why should I care if a species goes extinct? It’s not essential to my daily life”. But what use are humans, really? We waste a lot of resources and have managed to damage the ecosystem without a second thought. Eliminating species to extinction, destroying plants and trees a critical part of human well-being and organisms in an ecosystem leading to tremendous consequences.
Pieces of our own culture, of the very essence of humanity, are disappearing along with the animals and plants that used to dominate this world. (Glavin 3) Extinction is no longer just a natural process. It is an enemy, slowly changing our world into a barren wasteland where life is as rare as a flower in the Arctic Circle's winter. The wolf, the tiger, the caribou, the elephant, the bison, the cheetah, the sequoia cactus, the redwood tree – all of these and so many more things are on the verge of disappearing from our planet forever. Extinction is the most pressing environmental issue of our time, because if it continues the way it is going without anything being done to counteract its causes and consequences, there will soon be no environment left for there to be debates about.
The rate of extinction seems to keep escalating as time passes as well. Everywhere you go there are hundreds of species at risk of becoming extinct. They are threatened in every habitat of every continent. Freshwater habitats, especially rivers and lakes, are severely affected by species extinction because of the lackadaisical dumping of hazardous wastes. CAUSES OF ENDANGERMENT Now you might ask yourself, "why are so many animals vanishing off the face of this earth?"
Protecting the Endangered The beautiful species of the wild are being endangered more and more each day. Because of the increase of endangered wildlife society now faces several extinctions therefore, to prevent this problem, the government should pass laws or policies that provide greater protection and preservation, provide more information about endangered species, give more publicity to the issue and support charities. “An endangered species is one whose numbers are so small that it is at risk of extinction” (Do Something 2015). Species loss and habitat destruction is a large problem that is being faced. Naturally species will eventually die out due to the way of life but species becoming extinct has been happening more frequently all thanks to the lack of care from humans (Zoo Granby 2015).
The extinction of animal species increases the amount of carbon dioxide in the air, hence worsening the greenhouse effect. As species become extinct, out options for future discovery and advancement are also lost. Animal research has played an important part in mainly every medical breakthrough over the last decade. Benefits of Animals Plants and animals have many agricultural, commercial, medicinal and ecological benefits to human beings. Threatened and endangered species should be protected for future generations to be able to experience their existence and necessity.
