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 endangered insects, 12 endangered arachnids, 21 endangered crustaceans, 594 endangered flowering plants. Some main causes of Endangerment are habitat loss, pollution, hunting, competition from non-native plants and animals, plant collecting, logging, clearing forests, and trading animal parts. The growing population also causes some effect because man cause most problems. Diseases or viruses are al...
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). As a result governmental and societal action must be taken immediately!
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. Much has been done in the legal world to ensure the continued longevity of our planet’s diversity, including two major policies: CITES and the Endangered Species Act. Each of these policies has approached the welfare of endangered species in a different way, with varying degrees of success. Each strategy will be summarized and analyzed, beginning with the CITES treaty, as it was enacted before the Endangered Species Act. However, before examining the function and effectiveness of each strategy, it is important to understand the history behind each one of them.
Many animals depend on different environments such as lakes, oceans or the forest in order to survive. However due to human intervention such as pollution of the ocean, or heavy deforestation, many animals are at the risk of extinction. One such example is known as the Gundlach Hawk which due to deforestation is currently on the endangered species list. Due to it being on the list, conservation attempts are being made in order to keep the animal alive and save it from extinction.
Habitat destruction, deforestation, ozone depletion, global warming, and poaching. These actions and ecological happenings are creating a world where animals are going extinct at rapid rates. Our world is on the brink of what scientists believe is the sixth mass extinction. Unlike the five previous mass extinction, the latest one killing a majority of the dinosaurs, the main causes for this current extinction are anthropogenic reasons, not natural events.
...2100 if man continue on their harmful rampage. At the present time, there are 3,947 animals critically endangered and 5,766 endangered. The percentages of animals in danger of extinction are 41% of amphibian species, 33% of reef-building corals, 30% of conifers, 25% of mammals, and 13% of birds. Educator is the country with the highest endangered animals, with an insane 2,211.
Thirteen years ago, wolves were reintroduced to Yellowstone National Park. Of two potential locations considered (Snowflake Springs and Butte Rock) they were placed in the low-risk prey Butte Rock for the purpose of encouraging the wolves to spread out and create packs. Before and during the reintroduction project, Oregon State University researchers measured the rate of willow growth along 2.6 miles of the Gallatin River, which ran through Butte Rock and Snowflake Springs. During their study from 1998 to 2002, the researchers discovered that Snowflake Springs, where the elk were and no wolves lived, the willow growth dropped from 92% to nothing (“How Wolves Help Willows,” 4).
The National Wildlife Federation lists an endangered animals as a genus that may be eradicated by leaving an insufficient quantity to reproduce or obliterating the species in it entirety ("Endangered animals act," para 1). In the United States alone there are 70 mammals that are recorded as endangered; however the foreign number exceeds 250 (US Fish and Wildlife Service, 2014). The extinction process could be correlated to a natural route; however extinction may also transpire due to environmental differences. Climate variations producing even slight changes in characteristics may have an extreme consequence on an endangered species. Loss of habitation also impacts species causing them to becoming imperiled. On occasion ailments are distributed from domestic animal; due to the loss of habitation wild animals to come in contact with infected animals. For example Siberian tigers have development distemper from domestic dogs; and this has triggered the tigers to lose their fear of humans. This proves to be hazardous when the tigers approach villages and roads and are killed; furthermore the disease may cost the tigers their lives. (Dell’Amore, 2013). Many of the vanishing animals are poached for varies elements that may be utilized in traditional treatment. The African rhino is on species that is being significantly exploited for their horns; in Vietnam and China the horn is thought to treat everything from hangovers to cancer (O’Neill, 2013). In addition, the introduction of an exotic species afflicts endangered animals, and the overexploitation of animals initiates noteworthy reductions in populations. If an animal is not able to adapt to changing variations it could be disastrous to a species.
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. This problem has been going on for hundreds of years. There are animals and plants that can only been seen in paintings or early photography. It is because of our early ancestors that we have this problem today and we have to do more to prevent more animals and plants from disappearing forever.
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...
How would u feel if someone came in your neighborhood and destroyed your homes? So how would you expect the Sumatran orangutans to feel?
Invasive species are organisms that have “moved into an area in which it previously did not exist” (Snider, Mahan, and Holloway).Often times, the introduction of invasive species is usually for the purpose of controlling a native species that is considered a pest, but sometimes they are introduced because people are importing them as pets or ornamental plants, and even sometimes they are introduced as a mistake (Evans). Many environmental scientists consider invasive species as the most dangerous cause of endangerment, because they affect the biodiversity of ecosystems and biological communities, thus affecting the natural food webs and habitats of species. Ehrlich actually contributes fifty-four percent of the one hundred and seventy extinct species, of which the causes of extinction have been reliably identified, directly to invasive species (Ehrlich 37). Therefore, the introduction of invasive species to any new environment causes a threat to the ecosystems, as the foreign species will fight to survive and ultimately thrive in its new environment, meaning that invasive species hold the risk of pushing native species into extinction (Ehrlich
To become endangered means that a species is on the verge of becoming extinct. When the species is actually extinct, there are no more of them on the entire planet (wonderopolis.org). The two main causes behind this is due to the species either losing their habitat or from genetic variation (nationalgeographic.org).
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
Have you ever wondered how many plant and animal species are threatened by extinction? In an article of an issue of the Discovery Education magazine it stated “To date 16,928 plant and animal species are believed to be threatened with extinction.” (Extinction Facts) That is an enormous number and with the constant growing and changing world that number will only increase. Based on all the environmental factors placed on animals, the extinction of untamed animals is inevitable but, steps should be taken to preserve the remains of untamed animals so that scientific research can be conducted. Environmental factors such as deforestation, global warming, and evolution are placed upon animals and are major causes of untamed animals becoming endangered or extinct.
In our world today we have approximately 26,021 endangered species. Endangered species are organisms that may possible become extinct. The term 'endangered species' refers to all species that fits this description. However some conservation biologists and scientists normally use the term ‘endangered species’ to refer to species that are put on the IUCN(International Union for Conservation of Nature)Red List. Many factors can be looked at when considering the conservation status of a species. Factors such as human threats or environmental threats can cause a species to become endangered.
