Their physical characteristics make polar bears a perfect fit for the arctic. The polar bear’s oily and water-repellent fur allows it to easily shake off the water and ice that may have formed after swimming. Their thick layer of body fat and small ears enable them to conserve body heat. The bear’s white fur turns a yellowish color due to oxidation from the sun but still serves as camouflage. Their large paws have black pads covered with soft papillae, also called dermal bumps, which create friction and prevent slipping. Polar bears have partially webbed forepaws and elongated hind paws making it easy for them to swim (WWF: A Leader in Polar Bear).
Hunting was a major threat to polar bears in the 1960s. Hunters have taken to hunting bears from planes in Alaska. This sport hunting is now illegal. The bear’s fur is obtained as a trophy for the floor or to make coats; polar bears also provide meat. Until 1950, only Inuit’s hunted the polar bears barely killing one-hundred a year; now 700 are killed each year due to illegal hunting. Because hunters placed a great deal of pressure on polar bears, the International Agreement on the Conservation of Polar Bears was signed on November 15, 1973 in Oslo Polar Bears International).

- 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....

- When the congress passed the Endangered Species Act (ESA) in 1973, it recognized that ecological and scientific valued our nation and its people. It also expressed concern that many of our nation’s native plants and animals were in danger of becoming extinct. The purpose of ESA is to protect and recover species in their ecosystems, for which they have lived on. Under the ESA, species are specified into two categories; endangered or threatened. ‘Endangered’ means a species that is in danger of becoming extinct and has exceeded all of its range....

- The Endangered Species Act (ESA) of 1973, managed by both the U.S. Fish and Wildlife Service (USFWS) and the Commerce Department’s National. Marine Fisheries Service (NMFS), was created to provide protection for species at risk of extinction and the habitat in which they thrive. Work on developing an endangered species bill began in 1972 following President Nixon’s remarks in his “Environmental Message” (93 S. Rpt. 307). Nixon deemed the species conservation efforts of the United States insufficient and during the 93rd Congress, the Endangered Species Act of 1973 was introduced and passed on December 28th, 1973....

- The Endangered Species Act of 1973 The Endangered Species Act of 1973 is one of the most powerful tools that environmentally concerned citizens have to preserve biodiversity. Specific categories that the Endangered Species Act (ESA) includes are the listing of "Threatened species", "Endangered species", and the designation of "critical habitat". When these categories are identified, it is the U.S. Fish and Wildlife Service (USFWS) which assumes the responsibility of enforcement. Development of recovery plans, Biological or Environmental Assessments, and the development of Habitat Conservation Plans are just some of the tasks for USFWS (Smallwood, et al,)....

- America's Endangered Species Act Save the Bald Eagles. Save the whales. Save the Mountain Lions. Such were the environmentalists rallying cries that brought about the Endangered Species Act of 1973. Although, the first official endangered species legislation was a 1966 bill that called for saving U.S. wildlife, but lacked the powers to do so. The Endangered Species Act(ESA) of 1973 set forth the basic rules that apply in the U.S. today. Two agencies, the Fish and Wildlife Service and the National Marine Fisheries Service, are responsible for reviewing the status of species in trouble to see if they warrant listing as either threatened or endangered....

- The Endangered Species Act Introduction: Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65)....

- It's Time to Reform the Endangered Species Act In 1973, Congress passed the Endangered Species Act. The Act was passed in response to findings by Congress that growth and development were responsible for the extinction of species of fish, wildlife and plants. This Act was to provide programs to protect species identified as either endangered or threatened. It also mandated Federal agencies and departments to protect endangered and threatened species in their own operations, as well as work with State and local agencies to further promote conservation and protection of identified species....

- We have to put a stop to this and weaken the power that the Edangered Species Act has on us. People are getting laid off there jobs and millions of our tax dollars are being spent on the Endangered Species Act (ESA)all the time. Is it worth all of this for these endandered species. Must humans suffer and lose there jobs and houses over a few insects. Laws for the ESA are taking peoples property and fineing them because endangered species live on their property. A person is legally barred from using certain measures to protect his property from protected wild animals.... [tags: essays research papers]

- Have you ever seen a Philippine eagle flying graciously through the wild and lush jungles of the Philippines. 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....

- Humans are destructive. Not a lot of us think about how what we do affects the world around us. We almost act like we are the only ones on this planet. We go around polluting and destroying our world with no regard for our actions. The things that live out in the wild are paying the price for it. Every day that passes there is another animal or plant that is placed on an endangered list. This is happening at an alarming rate. Because of man’s desire to expand and conquer their surroundings, there are animals and plants that are on the brink of extinction that will not be around for our kids and future generations to enjoy if something is not done about it now....
