This report will be discussing and talking about endangered species and the impacts they have on ecosystems. Endangered species is a species of animal or plants at risk of extinction because of human activity, changes in climate, ruining of ecosystems, etc. This report will be split into different sections discussing different examples of endangered species and the impacts that they have on different ecosystems.
Blue whales, weighing in at 200 tonnes are the largest ever known animal to live on the planet. Sadly, after whaling has occurred it has made the species endangered with only 10000 to 25000 remaining. Blue whales play a significant role in keeping the food chain stable and helping with the reproduction of other species. In the marine ecosystem whales help control the distribution of food by helping to keep a stable food chain and ensuring that certain marine species do not overpopulate the ocean, however, Blue whales are being killed and the food distribution in the ocean is becoming unstable and causing major changes in the food supply of many other marine life A Blue Whale is able to consume as much as 40 million krill per day, so the impact on the marine ecosystem would be huge because overtime krill will overpopulate which causes problems in maintaining a food chain because the more krill there is the more food they will eat so because of their new overpopulation it could make other animals become extinct. If Blue Whales become extinct then marine life will
Do you know what the biggest animal ever to live on Earth is? You would be wrong if you speculated a dinosaur, elephant, or giraffe. You may be surprised to find out that the biggest animal ever to live on Earth is the Blue Whale and it is still alive today. The Blue Whale weighs as much as 33 elephants and consumes about 4 tons of food a day. I bet if you knew of an animal that was as long as 3 school buses you would want to keep this animal in the world forever. Although, the Blue Whale may not stay for long, many things affect the blue whale’s inhabitance, mainly the acts of humans have caused the Blue Whale’s to become endangered. Though, if you know the information about them you can help.
Since earth was created, there has been a natural phenomenon of species across the globe appearing and disappearing. However, in the past century, many species of animals have been disappearing at an alarming rate. Mainly, this rapidly occurring issue is caused by humans. Humans that contribute to the harmful actions that cause side effects such a pollution, deforestation, habitat loss and poaching. The natural rate of extinction pales in comparison to the extinction rate caused by all of these. According to the World Wildlife Fund, the current rate of extinction is 11,000 times greater than the natural extinction rate. Several different efforts have been made in order to stop or slow down the extinction of earth’s species. The Endangered Species Act is possibly the most successful example of these efforts. It’s main purpose is to get a commitment from the American people that they will work hand in hand to help save species that are at risk of becoming extinct and never returning. This act was put in place in 1973 and since then, no other law about the disappearance of wildlife has been quite as accomplished. Many different species that are protected under this law are either fully recovered or on their way to becoming safer. Laws like these are helping many different creatures left and right, however, at the alarming rate that they are disappearing, something else needs to be done. What people don’t seem to realize is that we depend on many of the animals that we are
Many species vital to ensuring that today’s environment will thrive are becoming extinct. If a species is slowly dwindling, and in imminent danger of becoming nonexistent, this species is considered to be endangered. “One in four mammals, one in eight birds, one third of all amphibians and 70% of the world’s assessed plants on the… IUCN Red List are in jeopardy” (IUCN, 2016). According to the International Union for Conservation of Nature, or IUCN, upwards of 16,000 species are threatened with extinction, including both plants and animals (IUCN, 2016). Before becoming endangered, a species will show warning signs, either by starting to lose biological diversity or by losing the habitats for that species to flourish in, or in the worst case, both. The word endangered can sometimes be confused with threatened, extirpated, or extinct. Extirpated refers to the state of a species where its population has died out in a certain area or range, but other populations of said species still exist elsewhere (Olden, Julian D., 2008). When a species is considered threatened, or vulnerable, this refers to the state of the species being susceptible to endangerment and extinction (“Extinction crisis escalates”). So if a species is threatened, the first signs of endangerment come along, which are similar signs to that of a species in danger of becoming threatened, including lack of genetic diversity, or overhunting may be evident. (“Extinction crisis escalates”). When a species is labelled
An endangered species is a plant or an animal at risk of becoming extinct. Scientists have estimated that up to one-third of species in the U.S. are at a high risk of extinction. In addition to donating millions of acres of land, this is essential to the recovery and survival of the endangered; the Act has shown a ninety percent recovery rate for species in the U.S. The main causes of endangerment include loss of habitat, excessive hunting, and pollution.
Issue: The environmental issue that I have chosen is the impact that invasive species have on the environment. The impact that invasive species have on the environment is vast, yet little is done about it. This issue is extremely important and will impact the world for generations to come. In this paper, I hope to learn about the effect they have on environment and what we can do about it.
The Everglades is known for its wonderful plants, birds, and reptiles, but what if those magnificent, beautiful things were gone forever. An Endangered is a species that is, or soon may be, in danger of being gone. A threatened species is a species that is very likely to become endangered in the near future unless the species or where it lives is fully protected for its survival. Eight million people and countless species of animals that call the Everglades home. Everglades contains many endangered species including the Florida Leafwing Butterfly, Green Turtle, Leatherback Turtle, and the Miami Blue Butterfly. The manatee is even federally listed as endangered. They are trying to make laws and develop projects to protect the Everglades Endangered
In today’s world, hardly any species of wildlife become extinct from natural causes. Europeans hunt animals to such an extent that we classify it as overhunting. We destroy their habitat, and introduce other animals that are a threat to endangered animals or are competition for resources and food. Habitat destruction is the greatest threat to both animals and plants.
Throughout evolution, many species have come and gone. What causes a species to become extinct and what can the human race due to prevent it? Many species’ population decline has been linked to human causation. An endangered species is defined as “plant and animal species that are at risk for extinction” (Funk). Endangered species can be placed into two more specific categorizes. Threatened species are species at risk for endangerment, while endangered species are at risk for extinction. Despite the fact that many people believe extinction is a major issue, the Funk and Wagnall’s New World Encyclopedia states that, “extinction is actually a normal process in the course of evolution” (Funk). Over time, numerous species have become extinct, usually as a result of climate changes, inability to adapt, or predation. Another major cause of endangerment is the human population. Pollution, global warming, and hunting is all causing a decline in the population of numerous species. While the encyclopedia is entirely fact based, many authors have worked to sensitize people to threatened species. For example, renowned author Sharon Begley, has written numerous articles to inform people of the importance of many species that are often overlooked.
Most people are familiar with the Endangered Species List which is a document that shows various fish, birds, mammals, and other creatures that are in danger of extermination from the face of the Earth. The lists served the purpose of ensuring that the government would do whatever was necessary to stop this from happening. When the Endangered Species Act was first envisioned, the idea was that creating a piece of federal legislation to prevent the killing of animals that had a severely decreased population would help to revitalize that species and prevent the animal's extinction. What started out as a grassroots campaign from concerned environmentalists and nature conservationists became a subject for political discourse and debate. In the Act of 1973, the policy outlined was that provisions would be made for listing species, as well as for recovery plans and designation of critical habitats would be founded for these species (Endangered 1973). It is somewhat fitting that a topic of such controversy would be put into law by a controversial Commander and Chief. President Richard Millhouse Nixon signed the Endangered Species legislation officially into law on the 28th day of December, 1973. Although the Act itself only came to the foreground of political attention during this era and the decade before it, attempts had been made to create similar types of legislation for nearly a century before that.
According to The Endangered Species Act of 1973, the term “endangered species” means a species which is in danger of extinction. The term “threatened species” is any species which is likely to become endangered. A species may be endangered, threatened, common, or abundant in different regions at the same time. For example, the Bald Eagle was common in Alaska but endangered in the lower 40 states of the United States. The primary reason for why species become endangered or threatened is because of the loss of habitat. Unfortunately, habitat loss appears to be evitable until humans minimize their consumption of natural resources. Unlike humans, who are capable of modifying their surroundings to cope with harsh or changing environmental conditions,
The three levels of biodiversity are as follows: diversity of the ecosystems, diversity of species within the communities and diversity within species. The loss of species within the ecosystems and within the community can cause a catastrophic result, as species live and feed on other species. Species close to extinction are endangered species, therefore protecting them from predators and offering the chance to reproduce and repopulate. Unfortunately, with little support within the environment, a species can become extinct due to population density. Proper monitoring of an endangered species is required in order to keep species actively reproducing and changing with the environment around them.
The Endangered Species Act of 1973 provides a program for the conservation of threatened and endangered plants and animals and the habitats in which they are found and deals with the perseveration of wildlife which is threatened with extinction. The U.S Fish and Wildlife services is the government agency entrusted with the enforcement of it provision.
As the largest known animal to have ever existed, the Blue Whale measures at 30 metres in length and weighs over 180 metric tons. This marine mammal belongs to the sub-order of baleen whales, in which filters are replaced by traditional teeth within toothed whales. For decades, these majestic creatures have ruled the seas worldwide, attracting tourists and scientists to take part in the peaceful nature of the Blue whale. However, even the Blue whale, whom has been around for over 55 million years, were placed on the WWF endangered list in 1970. Without support from both Marine corporations as well as the general public, it is likely that the Blue Whale will soon end its 55th million year of ruling the ocean waters of planet Earth.
The Blue Whale has been an endangered species for a really long time now. People believe that the blue whale is the largest species that has ever existed. In the world there is 3 different types of blue whales. You have the Northern Blue Whale, the Southern Blue Whale, and the Pygmy Whale. The blue whale population is going down because people are hunting them. These humans have been hunting these whales for over 100 years now. The Blue Whales are now in a legal protection and the last whale that was being hunt was in the 1970s. The Blue Whale plays a big important part in our health. They help grow our ecosystem and now that they are not being killed or hunted they are starting to have more and more Blue Whales.
Bill Freedmen, author of “Endangered Species—Human Causes Of Extinction and Endangerment” notes, “scientists approximate that present extinction rates are 1,000 to 10,000 times higher than the average natural extinction rate.” These distressing numbers should be acted upon to save the endangered species and avoid the catastrophic change to this planet if these species were to become extinct. In order to produce change, people need to recognize that habitat loss, climate change, and poaching are all factors in why our animal species are going extinct.
