Intro: I will be doing my report on tigers. Tigers have more than 100 stripes‚ and no two tigers have the same stripes. Another interesting thing about tigers is that the roar of a tiger can be heard more than a mile away. Tigers are also an endangered species. Made of cells: Tigers are multicellular. They have skin cells‚ blood cells‚ ad brain cells. They are an animal cell. Need Energy: Tigers are heterotrophs which means that they get their energy from the food that they eat. Tigers

the future usability of the resource. Living resources are renewable‚ minerals and fossil fuels are non-renewable. Wildlife conservation is the preservation‚ protection‚ or restoration of wildlife and their environment‚ especially in relation to endangered and vulnerable species. All living non-domesticated animals‚ even if bred‚ hatched or born in captivity‚ are considered wild animals. Wildlife represents all the non-cultivated and non-domesticated animals living in their natural habitats. Our own

unique wildlife is the Lemur. There are over 50 varieties of this primate‚ and all of them are endemic to Madagascar (wildmadagascar.org‚ 2007). Unfortunately‚ Lemurs are on the endangered list as a threatened species. There have been 45 species recorded as extinct on Madagascar‚ and many more species are on the endangered list. The threatened list includes 57 birds‚ 51 mammals‚ and 61 fish species endemic to Madagascar (biodiversityhotspots.org‚ 2007). The island also has some severe environmental

Anthropogenic means the extinction is caused by human actions. For example‚ species like the Bengal tiger‚ primarily in India and black rhino on the coast of east Africa. The Bengal tiger makes the endangered list and the black rhino makes the critically endangered because of early hunter’s. Bringing back some already extinct will give justice to those who promote conservation. Re-establishing lost value is another argument to bring back some lost value over hundreds of years.

If I was writing a report on an endangered species I would choose the sea turtle. The reason I would choose the sea turtle is because in our source “Turtles in Trouble” it gave us the story of a turtle named Adelita. This turtle traveled 6‚000 miles alone to Japan. To me that is pretty amazing that a turtle can remember where she laid her eggs especially since it is very far away. Another reason I choose this article is because was pretty reliable. This article was reliable because scientist Jay

White tigers are an endangered species and it is said that less than a dozen have been seen in India in about a hundred years. In fact no sightings have been reported since 1951. This may be caused by the fact that the Royal Bengal tiger population has dropped from 40‚000 to 1‚800 in the past ten years and as few as one in every 10‚000 tigers is white (www.cranes.org/whitetiger). White tigers are neither albinos nor a special species. They differ from the normally colored tigers by having blue eyes

further reports that in 1992‚ a prominent US linguist had stunned the academic world by making prediction that ninety percent of the world’s language would have ceased to exist by the year 2100. Currently‚ there are about 473 languages classified as endangered language as collected by a global database of languages‚ a US organization owned by Christian Group SIL International. This critical issue is however neglected as stated by a prominent French linguist‚ Claude Hagege‚ “Most people are not at all

When we think of a worldwide catastrophe‚ we usually think of earthquakes‚ ice age‚ and nuclear war. But one that should be recognized with much more severity is poaching. As international editor Richard Swift observed; “We are pushing a hundred species a day‚ four species an hour‚ into evolutionary oblivion”. Hunting and capturing animals has been practiced even before recorded history. Where this can be understandable to most in a survival perspective‚ there are people in this world who abuse this

Endangered species are those that are approaching the inability to reproduce or maintain a sufficient steady state population. They are approaching a bottle neck that without involvement‚ nature will eliminate their existence on earth. Although humans seem to interfere and even initiate this decline of animal population‚ we ourselves are a product of nature‚ and if allowing extinction benefits the overall wellbeing of our species‚ then it is our natural obligation to allow such extinction to take
