FACTS & HISTORY
What exactly does the term endangered species denote? There can be numerous definitions that correctly describe the term. It is any plant or animal whose survival is in jeopardy of becoming extinct. Extinction, of course, is when the species no longer exists, and there is no way it can be brought back to this earth. In most cases, the cause of this displeasing calamity is generally human-related.
As more time goes on, more species are in peril of becoming extinct. The rate at which they are being lost is startling, even when compared with the catastrophe of the extinction of the dinosaurs approximately 70 million years ago. Nobody knows exactly what the current extinction rate is, but according to leading scientists it is around 1,000 to 10,000 times greater than normal. 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?" Well, there are several different causes for the extinction of hundreds of endangered species. As I already stated, the majority of this lies on the shoulders of the disgraceful, careless measures taken by the human race. Hunting is one of the main reasons for animals in the wild becoming extinct. The animals are sought after for food, for their skin, and in some cases, even their bones. Water pollution and air poll...

...g programs. In some places, species have been reintroduced to parts of their former range, and are increasing.
There is also a new method that scientists are trying to use for the conservation of endangered animals. Sperm freezing, artificial insemination and embryo transfer are routine methods in several domestic species and applications of these techniques may also be used in wild species. However, reproduction physiology is very specific and before any technique can successfully be applied, the main reproduction features must be examined in target species or at least in a nearby relative species.
In conclusion, for the species crisis to be addressed effectively, far greater action is needed. These issues are being tackled slowly, but hopefully the human race will realize how important wildlife really is, and start supporting the endangered species.

- How well informed are you about global warming. Do you know that by 2030, at least 18% of the world’s coral reefs will be gone. Do you know that by 2050, up to 400 species of bird will be endangered or extinct. Do you know that by 2080, New York City will be under 3 feet of water due to rising sea levels. Most of these facts are not well known and the World Wildlife Fund (WWF) seeks to change this. The WWF’s “mission is to conserve nature and reduce the most pressing threats to the diversity of life on Earth” and this mission statement is displayed effectively through their advertisements- specifically their homeless animal campaign....

- In the world today there are about five thousand endangered species. Around one specie dies out every year. Some animals become endangered because people are killing them for their horns, as in the case of the Black Rhino of Africa. Others become extinct because pesticides are put on the food we eat, causing the animals that eat the insects off the plant to become contaminated, which causes their predators to become contaminated, which often affects the shell of that organism?s egg. Here is a list of the endangered species, 91 endangered birds, 76 endangered mammals, 36 endangered reptiles, 21 endangered amphibians, 115 endangered fish, 70 endangered clams, 35 endangered snails, 44 endangere...

- Most people love animals. They can take a trip go to the zoo to look at various animals that come from many different parts of the world. Depending on the zoo you go to, you can find lions, monkeys, exotic birds, penguins and etc. A goldfish is usually recommended as a great first pet for a child that is looking for responsibility, because they are low maintenance and their life expectancy is short. An amusement park like SeaWorld, has whales, sea lions, penguins and many other water mammals at their parks for our entertainment.... [tags: Killer whale, Whale, Endangered species]

- In today’s society everyone seems to have an opinion on everything. It seems the more uninformed one is on a subject the more strongly the feel about it. Occasionally there are those who address issues they are well informed on in a well-organized and civilized manner, weighing both the pros and cons of the side they advocate. Brandon M. Middleton does an exceptional job of this in his article on the Endangered Species Act, where he talks about the effectiveness of the Federal government’s current involvement with endangered species....

Have you ever caught a glimpse of the alluring, pristine and stunning Kakapo bird flying freely in the small island of New Zealand before. If not, then you are fortunate as these marvellous birds are slowly recovering from their severe endangerment. However, many beautiful and ravishing animals that reside in the United States may never be seen again. This is because the United States Government does not provide adequate, efficient or productive methods to save these species and the government desperately needs to improve their methods and ways....

- Every Jaws fan knows the shark gets it in the end. What they do not know is that too many sharks have gotten it; and that has caused a rapid decline in the shark population over the past thirty years. Since the 1970's, sharks of the Atlantic and Gulf of Mexico shores have declined eighty-five percent. Sharks are vital animal to our world's ecosystem, and if the decline is not controlled; we could be facing devastating problems in years to come. Information has been obtained from two books: The Shark Almanac by Thomas B.... [tags: Sharks Extinction Population Endangered Species]

- The latter half of the twentieth century was host to the greatest and most widespread advancements in environmental awareness in human history. It was during this time that people began to consider the effects of their polluting cars and their wasteful habits. People began to realize that something must be done to curb humans’ negative impacts on their surroundings and thus the environmental movement was born. One of the most important factors that resulted from this expansion of environmental consciousness occurring over the last several decades has been the protection of endangered species....

- The Endangered Species Act was established in 1973 to protect endangered species. Climate change, caused by anthropogenic greenhouse gas emissions, has serious consequences for many species, but it is a great concern for polar bears. Polar bear populations are susceptible to climate change, hunting, and habitat alteration. They are the world’s largest terrestrial carnivore and because of their strength polar bears are the symbol of the Arctic. Their physical characteristics make polar bears a perfect fit for the arctic.... [tags: Endangered Species]
