...becomes warm can cause coral bleaching which makes the tissue of the coral to become white. That does not mean that the coral is dead in any way, but make the coral become weakened than its original standard. In the Caribbean they have lost 50% of there coral reefs because of the bleaching in one year. But not only are the reefs becoming white because of warm water temperatures also cold temperatures also cause coral bleaching’s in Florida. This made some corals die. Coral reefs provide sea creature’s shelter, secure shorelines, and back fishing industries. The factors for coral bleaching are changes in salinity, diseases, bright sunlight when the water is already too warm, and pollution. There are ways to prevent it like walking instead of driving, plant a tree anywhere, and support local legislators. What is an ecosystem? An ecosystem is living things like plants, animals, and organisms. These depend on non-living things like water, sun, temperature, pressure, and nutrients. What causes ecosystem destruction?...

...“Nothing is more priceless and more worthy of preservation than the rich array of animal life with which our country has been blessed.” Said by Richard Nixon. The Endangered Species Act all started in 1973 when president Nixon signed it and made it into a law. It’s been a act for more than 40 years. Many people support and believe in this act, which is good because it helps the animals and helps the world as a whole. Although the Endangered Species Act can be costly, it has a very important impact on animals that are both extinct and endangered animals that need conservation. First off, some people may say that the act can be very costly at times. They believe that it can be too overfunded, and that’s not the case. While on the other hand...

...Hunting Helps Animal Populations Imagine a world without lions or deer? Hunting helps control the population of animals. If no one went hunting there would be too many animals in certain areas. Deer over populate and wander down into neighborhoods. They cause a lot of problems when they get into the cities. There is a difference between hunting and poaching. Hunting is hunting an animal with a tag or a license. Poaching is hunting an animal without a tag or license; illegal hunting. Poaching and habitat lose is the two main reasons making animals go extinct or endangered. Hunting helps control the animal population; poaching makes them extinct or endangered. When you go hunting you have a tag and a license. Poaching is when you go hunting but you don’t have a tag for that animal or you don’t’ have a hunting license. Many countries have put bans on animals that live in that area. “Bans clearly not only do not work, but accelerate the extinction of species” (Bore). The lion has not been allowed to be hunted, in Kenya, for over 30 years. During that period, the size of the lion population has dropped to ten percent of the neighboring Tanzanian lion population (Bore). The Tanzanian lions has been allowed to be hunted for the same period of time as the Kenya lions have been banned. The numbers in different countries are rising for the animals that are being hunted legally, but for Africa, the numbers are dropping. Not only does hunting help with controlling animal population, it...

...Title: the extinction of Mammoth Introduction * Location and life of mammoth * Causes of extinction * Reasons for extinction Body Causes for extinction * activities as cause of mammoth extinction * Climate change in the extinction of mammoth(climate warming) * Loss of habitat * Radiation cause Reasons for extinction * Hunting and poaching * Protection from mega fauna animals. * Habitat loss due to vegetation and other factors * Use of skin for cloths and horn for ivory item. etc. Summary Mammoth is a large and extinct elephant of the Pleistocene epoch; these types of elephants were hairy and had a sloping back and long curved tusks. These big elephant has gone extinct and throughout this paper I’ll be talking about how these mega fauna animals have gone extinct, what caused their extinction, the reason for this extinction etc. Mammoth are thought to be extinct due to the climate change because they used to live in glaciers areas, they are also thought to have gone extinct because of man activities on them like hunting and poaching. The last thing I’ll be talking about in this paper is the reason why these animals have gone extinct.

...Urbanization is another leading factor to the sixth mass extinction. Brian Czech, in an article titled Urbanization, habitat loss, and extinction in nineteenth-century America, Holley 2 states, “Urbanization endangers species by replacing habitat directly and by depleting resources needed to support urban economies.” People are taking away these animal’s homes and replacing them with resources that only benefit humans and the economy. These animals are forced to survive without the resources and environment they are used to (chicagobotanic.org). Urbanization does not only affect the animals on land but it also affects the species in the ocean and their habitats. Urban Runoff is a huge threat to species in the ocean. Urban Runoff happens when...

...Most people go through their lives not worrying about when humans may go extinct. In the past, there has been five other mass extinctions. About 450 years ago was the first mass extinction called the late Ordovician, followed by the Devonian, Permian, Triassic and the Cretaceous extinction. All of these extinctions were caused by similar changes. The question is: Are humans in a sixth extinction? The answer is yes, humans are in a sixth extinction because of the extinction of multiple animals, humans, global warming. In the last 500 years scientist know of approximately 1,000 species that have gone extinct. From past mass extinctions more than 75 % of life went extinct. According to research at Global Biodiversity Outlook between the years of 1970 and 2006 the population of wild vertebrate fell by average of 31% and the numbers keep inclining. Another research team from the National Autonomous University of...

...The Anemones provide food, and protection for the Clownfish. Clownfish hold a very important scientific value, because they are able to be captive bred. Meaning that they can be bred in captivity (labs), as well as they have one of the most prominent symbiotic relationship with the sea anemone which scientists have studied to find similarities with other symbiotic relationships between other animals and, to determine how it originated and how it has evolved. Ocean acidification has most defiantly affected every marine species especially the clownfish, the clownfish have an incredible sense of smell and the acidity has disrupted the larvae's ability to develop their sense of smell to the max, leaving many clownfish unable to clearly smell their predator awaiting their next meal, or tell which is their specific host Sea Anemone, as well as their food, they experience this disruption in the larvae stage, when they are developing and do not fully develop their sense of smell. Ultimately, their sense of smell deterioration makes clownfish quite susceptible to the 30% increase in the acidic levels in the ocean. The acidification has also...

...Zeke Moisey Mrs. DeMarco Honors Environmental Science 27 November 2012 Chapter 4 Test Questions 1.(5pts) Why are large animals that we tend to value (bison, whales, etc.) more likely to go extinct than smaller ones that are nuisances (mosquito’s, mice)? Larger mammals, on the other hand, must endure the hard times when there’s little food or extreme weather. Their large size constrains them from digging burrows or lowering their metabolic rates for extended time periods. In a sense, larger mammals face the elements head-on like a fearless adventurer who might not make it through alive, and is forever changed by the experience. On an individual level, large mammals tend to live significantly longer than smaller ones. For example, elephants can live up to 70 years, while shrews are lucky to reach two. Because of their faster generation times, small mammals should evolve faster, and small mammal species and genera should appear and go extinct faster – but this is not the case. But overall, small mammals’ ability to hibernate or enter a state of torpor seems to give them the largest benefit for prolonging their species duration. And the small mammals that didn’t hibernate had relatively faster evolution rates, as they were forced to cope with the elements. The longest living genera in the study were a mole, two gliding squirrels, and two dormice, which lasted about 16 million years, and all had the ability to burrow or hibernate. The tapir was the only large mammal that...

...thousand more have lived previously and become extinct. Most of these extinctions occurred before humans evolved, and the species are known to us only through fossils The Dodo The dodo was a large (50 lb) flightless bird that lived on Mauritius, an island in the Indian Ocean. It lived undisturbed for so long that it lost its need and ability to fly. It lived and nested on the ground and ate fruits that had fallen from trees. The island was uninhabited and the dodo had no natural predators. Then Mauritius was colonised in 1638. Dodos were hunted for food and easy to catch because they were not afraid of people. New competitors were brought onto the island (including pigs, cats and rats). These competitors ate the dodos' eggs in their ground nests and also ate the dodo’s young. The last dodo was killed in 1681. Answer the following questions using information from the text: 1. What was the dodo? 2. Out of the four causes of extinction we have learnt about, which two caused the extinction of the dodo and why? 3. When did the last dodo die? Dinosaurs There are many theories as to how the dinosaurs became extinct. Keep in mind that there is no absolutely proven theory. Asteroid Theory According to this theory a large asteroid or comet collided with Earth about 65 million years ago. Scientists think that such a large collision would throw so much dust into the air that sunlight would not be able to shine and plants and animals would die. The dramatic changes in climate that...

...It is estimated that approximately half of the species alive on Earth today will become extinct within the next 75 years and around 10,000 species/subspecies are presumed extinct every year . This is due to human impacts such as industrialization/urbanization in one’s habitat and hunting; the extinction can also be a result of the animals incapability of surviving in a given location, ,and or an increase of one’s predator population .By definition an animal goes extinct when the last member of its species dies.From the beginning of Earth’s existence species of all shapes and sizes have walked the Earth but for these billions and billions of years close to 99% of them have died out for a great number of reasons. A status with such a melancholy tone can be traced back to a unfamiliar sizeable bird who once roamed the modern day Australian island Tasmania. The Tasmanian Emu, who is thought to be a subspecies of the modern Emu; and is thought to have been isolated from the mainland Emu during the Late Pleistocene. The Tasmanian Emu resembles the current animal very well both being Oviparous and...

...Once a long time ago, our ancestors needed to hunt for food. When they caught an animal that they could eat, they cooked it and ate it because that's what the needed to do to survive. But, they did not hang the head of the animal they killed on the wall, and they did not sell the animals tusks to another family. Unlike our ancestors, many people in our era do those exact things. A majority of the people who participate in trophy hunting believe that it helps conservation and population control. The sad truth is that it does not. In fact, trophy hunting is a cruel sport that should be banned. In trophy hunting, instead of letting the weakest of the species due off, trophy hunters kill the cream of the crop (In defense of the Animals). This...

...Many animals are on the endangered species list. Some of these species eventually go extinct. There are different variations of severity of the list. Polar bears are on the endangered species list due to global warming. Panthers are on the list due to humans hunting and killing them. Polar bears and panthers are endangered species. Habitat Polar bears may be found, “in the U.S.(Alaska), Norway, Canada, Russia, and Greenland on numerous frozen seas and bays” (Alongi 1). They can be found all across the arctic. They spend a majority of their lives on water or frozen sea ice caps. The polar bears rarely touch solid ground in the short arctic summer. The polar bears depend on the sea ice to hunt and store energy for the summer, but the ice is melting earlier and freezing later. Their habitat is not the same as it used to be. Panthers live in forests, swamps, and prairies, and they are territorial animals who travel hundreds of miles within home range. “Destruction, degradation and fragmentation of habitat are the greatest threats to panther survival” (Threats to Florida Panthers 1). Panthers prefer warm climates over cold climates. More panthers are being lost every year due to humans hunting them, global warming, and pollution. The panthers’ status will continue to go down unless we stop killing them and...
