Human effects and involvement on endangered
and extinct species
Tiffany Tierson
Abstract
This paper was constructed to give an overview of the vast majority of species that are disappearing and have disappeared from the earth. With informative knowledge and accurate numbers the reader was introduced to the different ways that animals are becoming extinct, deforestation, overpopulation, economic prosperity, population growth, urban environment, global perspective and science and ethics. Each of these is affecting different species at different rates, but what was concluded by comparing numbers is that humans are truly responsible for their actions and the actions of causing the exaction and endangerment of animals. Humans are the underlying cause. This was not always the truth but over time like the species has evolved; human’s habits have evolved to hinder the animals. The choices that humans have made over the centuries have hindered the earth and its creatures on it.

Introduction
Man has relied on animals as far back as time can show, using them for food, shelter companionship and much more. What happens however when the reliance becomes abused and the resource begins to disappear? Over time animals have begun to disappear off the earth at a more rapid rate than what nature would suggest. Deforestation, overpopulation, science and ethics, urban expansion and global warming are just five of the main reasons humans can be to blame for the extinction and endangerment of animals. I have researched about the following species, the Philautus poppiae frog native to Sri Lanka, the Asian elephant, the Siberian tiger, giant panda and the polar bear. Each species seems to be declining at a rapid rate, but why? Some would suggest that animal endangerment and extinction is a natural process, which to some extent is true, but over the last century humans have watched as animals have become extinct in front of their faces, the most famous perhaps the dodo bird. The dodo bird native to the island of Mauritius in the Indian Ocean became extinct in 1681 when humans arrived on the island and began to populate. The bird not having any natural predators began to die off like wildfire when humans began to feed on their eggs and the bird itself. (Eschberger, 2001). We are lucky that this was even recorded seeing as many species of animals are becoming endangered and extinct everyday without even being noticed. This is why I have composed a paper to say that the endangerment and extinction of animals can be held responsible by humans. Beverly Eschberger points out in her paper Extinction V: Modern Extinctions that before humans it has been estimated that species would disappear at a rate of one species per million years. This is a drastic change compared to now where 27,000 species go extinct each year in the rainforest (Eschberger, 2001). The purpose of this paper is to expose the facts using the species listed above and the human preformed actions to express why humans are at fault for the endangerment and extinction. My hopes are that if these reasons can be exposed than maybe there can be more done to put a stop to animal loss. Materials and Methods

The method in which I carried this experiment out was to zero in on five human activities that are endangering and causing animals to go extinct, the five focuses were deforestation, overpopulation, science and ethics, urban expansion and global warming. When focusing in on each activity I also focused on an endangered species that was specifically associated with it, although a wide variety to choose from I narrowed it down to one species that has become endangered and one species that has gone extinct for each activity. The Philautus Poppiae and Deforestation.

The Philautus Poppiae is a frog native to Sri Lanka. According to its discoverer, George Meyer, the frog resides in Rakwana Hills exceeding an elevation of 1,000m. From this Meyer at the time concluded that the amount of...
