Over the last hundred years, hunting and forest destruction have reduced overall tiger populations from hundreds of thousands to perhaps 3,000 to 5,000. Tigers are hunted as trophies and also for body parts that are used in traditional Chinese medicine. All five remaining tiger subspecies are endangered, and many protection programs are in place. Poaching is a reduced—but still very significant—threat to Siberian tigers. Tigers live alone and aggressively scent-mark large territories to keep their rivals away.
(WWF) We run the risk of losing them forever. And yet, although they are a universal symbol of wildlife diversity, they continue to be hunted for their flesh, hide, tusks and ears. Between 1979 and 1989, worldwide demand for ivory caused elephant populations to decline to dangerously low levels. During this time period, poaching fueled by ivory sales cut Africa's elephant population in half. Since they were big targets and sported the largest tusks, Savannah elephants took the worst hit.
With less than 300 still alive, the Cross River Gorilla is the most endangered subspecies, even classified as critically endangered and one of the 25 most endangered primates by the IUCN (International Union for Conservation of Nature). These beautiful animals are in serious danger, and
A war between the two immediately broke out. In 1964, the USA entered the Vietnam War. The inconclusive war in Vietnam cost many American and Vietnamese lives, devastated the country, and achieved nothing but misery for anyone caught up in it; including the Cambodians. Cambodia had become part of the Vietnam battlefield. During the next four years, American B-52 bombers, using napalm and cluster-bombs, killed up to 750,000 Cambodians in their effort to destroy North Vietnamese supply lines.
As a result of European settlement, many populations of Native Americans were brought to near extinction. The hunger for a new and free word had blinded Europeans’ humanity towards the Native Americans that had lived in these lands for hundreds of years from the Atlantic to the Pacific in harmony and respect of their lands. The discovery of gold was of the most important factors that promoted violence against the Native Americans. When gold was discovered in California in 1848 it initiated a large amount of migrant traffic across the North American continent. This large influx of Americans brought more diseases to the Native Americans that devastated their tribes with great number of deaths.
The Biodiversity of Yellowstone National Park Introduction Biodiversity is immense in Yellowstone National Park and has been the pinnacle for biodiversity in the United States for over a hundred years. Since Yellowstone is the summit for biodiversity, the need to keep the plants, animals, and natural features preserved and protected is essential. Biodiversity includes all living organisms on earth and Yellowstone National Park has species still living in its boundaries that have disappeared in other parts of the world due to development, habitat fragmentation, climate change, invasive species, and other posed threats. The park allows for scientists and visitors to learn about nature in a place largely free of human influence (US Department of the Interior, 2011). The mission of Yellowstone National Park is to encourage awareness and application of wide-ranging and high-caliber scientific work on the region’s natural and cultural resources.
After the Black Saturday bushfires, many people died and many properties were destroyed, causing grief to the owners, friends and family of them. The money to repair the damage was a big problem because of the bushfire’s immediate wreckage, and the survivors ran out of money before they could even finish the houses, and with the add-on of fireproofing this raised the cost to rebuild. What were the environmental impacts from the Black Saturday Bushfires? The environmental impact from the Black Saturday bushfires was the biggest impact, as more than a million animal wildlife injuries and deaths would tally more than 1 million. There was 1 specific wildlife, the Lead beater’s Possum, which only had one habitat, and unfortunately was part of the Black Saturday bushfires, which puts that animal on the list of “threat of extinction.” http://youtu.be/EmG5kQBsOpg Black Saturday- Inside the firestorm ABC1 Video about what happened inside the firestorm.
The decline of the populations of Bald Eagles was because of the destruction of habitats, shooting and DDT and other contaminants. As late back as the 1960’s, human disturbance was also proposed as a cause of the decline. Today, human activity still disturbs the activity of the bald eagle. Eagles are very sensitive to humans and their activities, and they are known to usually be found in places far from human disturbance. There are many observations and research recorded that documents the many activities of humans that are a disruption to the activity of the bald eagle.
White Siberian Tiger There are many endangered species. Over 10, 801 different species are considered to be endangered. An endangered species is a population of organisms that is at risk of becoming extinct. This is caused by human’s destruction of habitats and poaching. In order to prevent more species from becoming extinct, the endangered species act was enacted.
According to Mayra Calvani in her journal in World Society for the Protection of Animals (WSPA) mentioned that in Latin America and Europe, around 250,000 bulls die per year due to tortured and killed for entertainment purpose especially in bullfighting. (M.Calvani, 2008)². This shows that, keeping animals for entertainment purposes promotes animal abuse. Secondly, captivity also takes away animals’ freedom. Many of wild animals cannot cope with situation that they are taken from their natural habitats and placed in captivity.
