Endangered Species Act Throughout history, there have been many species that have passed through our planet, earth. Some have survived for millions and millions of years, and others… well, they weren’t so lucky. According to Biologicaldiversity.org, many scientists believe that as of now, “our planet is now in the midst of its sixth mass extinction of plants and animals.” Many scientist claim that species are dying out at 1,000 to 10,000 times the normal rate (the normal rate being 5-6 species per year) at this rate, as many as 30 to 50 percent of all species may be extinct by mid-century. This is why in 1972, “President Richard Nixon declared conservational efforts in the United States aimed toward preventing the extinction of species.” (www.fws.gov)
animals and plants, aquatic and terrestrial) all around the world are involved (Benton, 2011). There have five major extinction events in the last 600 million years ago, the Late Ordovician, Late Devonian, Late Permian, Late Triassic and end-Cretaceous (K–T), respectively in that order (Twitchett, 2006). The Permian-Triassic mass extinction happened in between the Palaeozoic and Mesozoic eras, about 251 million years ago (Jablonski, 1995). This mass extinction was the most devastating by a big margin, this claimed 95% of all aquatic species, which dramatically changed life in the ocean. Land plants and
This project is just one example of the many ways that Ducks Unlimited works in the environment. “The decline of waterfowl populations and the loss of wetlands are high-ranking environmental concerns in North America.” (Granzio and Cross, 1). Ducks Unlimited is important. Without their projects and work, waterfowl levels wouldn’t be where they are today, which would be damaging for the environment. The National Fish and Wildlife Foundation’s main focus is to protect the animal, the environment, and to make sure that these things increase in size and numbers.
However, Kolbert fails on a much greater magnitude than just this small section of the finale. Throughout the entirety of the book and especially in the conclusion, the author describes an unavoidable sixth anthropogenic based extinction. These theme of inevitability is present in nearly every chapter. The frogs cannot be released back into the wild (14), the mastodons, penguins, and ammonites are gone, we are reversing “geologic history not only in reverse but at warp speed” (124), coral and trees have already died, and we have hunted the megafauna into extinction. Like mentioned in the previous paragraph, Kolbert was perhaps being diligent and did not want to dilute her work with hypothetical models and predictions that mapped the future; in this case, one would expect the author to bring up the benefits of environmentally friendly
This essay you will earn important facts, whether the number of creatures have increased over time. I will be telling you why their number of creatures have increased or if they have not increased. Has the number of creatures on Earth increased or decreased over time.The reason creatures has increased over time is because creatures has multiplied over the time. A lot of creatures decreased when the mass extinction happened, wiping out all the dinosaurs. This topic is very important because some creatures have started to go extinct.In my position that the number of creatures has increased over time, that the number of creatures are going to continue to increase.In this essay you will read about the number of creatures back then, you will also learn how the animals over time increased.
After an outbreak of the plague devastated release sites in 1999, the ferret and prairie dog populations dropped significantly. The WWF provided aid in creating plague management, and in 2013 and 2014, 52 black footed ferrets were released onto a reservation (WWF). The loss of the black footed ferret would not have a large global affect, as it only resides in North American grasslands. Its loss would have a large affect locally because of the black footed ferrets’ influence in its habitat. Without the black footed ferret, the prairie dog population would be affected negatively.
Although Odysseus was only supposed to be gone two weeks, it still caused worry and concern. Odysseus caused pain by being gone for twenty years. No one in the family knew where Odysseus was. He was assumed to be dead. Him being gone for twenty years, caused Telemachus to have an identity crisis.
According to the text, “Only 16 species have established self- sustaining population in the wild as a result of captive breeding efforts, and most of those programs were initiated by government wildlife agencies- not zoos” (Laidlaw). Secondly, Laidlaw helped support his claim by listing different ways that animals can suffer in zoos. For example, “Studies have shown that animals can suffer physically, mentally, and emotionally” (Laidlaw). One time I went to the Memphis Zoo in Tennessee and it was around 100 degrees and there was no running water. I am not a supporter of animal cruelty, so if these are ways animal are being hurt, I will not support it.
Back before the 19th century before the United States government passed laws and set aside national parks and national reserves for wildlife and their safety (Careers in Focus 61-62). Animals were going extinct, and way too many of them were being hunted and fished daily. Fisheries and reserves have been established by the
Animals in Their New Natural Habitat Why are different species becoming extinct? Do researchers know how many innocent animals are killed each year? When will animals be protected in a comfortable habitat? In man-made environments, such as zoos and other nature parks, animals that are born in the wild are protected and well taken care of. Due to animals running around in the wild, scientists and researchers can track the amount of animals being killed everyday.
