Species Extinction: A Pathway to the Sixth Extinction We have all played a game of Jenga, each player removes one block per turn and either the tower will remain upright, or it will all tumble down. This Hasbro game is an exceptional example of the sixth extinction. Simply imagine each block as a different species. Humans are on top while other species like rhinos, polar bears and lions are on the bottom. If one is removed off of the bottom there is a possibility of all of them toppling over,…

Current conservation programs are focused on the species level because in order to develop a strategy for conserving biodiversity, a substantial awareness of the abundance and distribution of species throughout the world is required (Textbook pg. 53,60). Our current knowledge of the amount of species present on Earth is imprecise for a variety of reasons; however, in order to move forward with protecting biodiversity, conservation biologists must have at least minimal knowledge of what they are…

scientists have written about how species have become to what they are today, each having their own take on how species came to be. The most common explanation is that species evolved overtime. In the Origin of Species, Charles Darwin explains how he believes species came to be through the theory of natural selection. Darwin draws on anthropology, demography, and political economy in his theory by utilizing them to support how natural selection has caused species to evolve and adapt in order to…

Animal extinction is a huge epidemic that is happening faster than we ever expected. Endangered species are dying off left and right due to natural and unnatural causes. Things like poaching and global warming are constantly effecting our environment and changing the way species are living every day. All humans have a responsibility to take care of our environment, which, in turn, will help protect our species and others as well. The protection of Earth is vital to our survival as a whole and…

Endangered species should not be killed they are rare, most become extinct people kill them for games. One reason that animals are becoming endangered is because humans are trying to get timber and find new places to settle or sell and destroying their homes. Other reason are because people hunt and fish for food. Tigers are hunted because of games and medicine and people use they fur. Some are killed because of bad behavior and are hazards to human life. Also,because of climate changes and…

The Endangered Species Act, like many of the conservation acts, was put in place because people noticed something needed to be done. Although this act is very complex and can be confusing, it has been successful. Nonetheless, since many species are still listed or waiting to be assessed people criticize the act’s effectiveness. In 1966, congress passed the Endangered Species Preservation Act. This listed native animals as endangered and gave limited protection. The act was amended in 1969 to…

it? In my opinion, I believe that we should kill species that have invaded a certain environment where they weren’t there in the first place. One reason is that invasive species cause untold amounts of damage to the environment that they conquer. Another reason is that we caused the problem, so naturally we should fix the problem. Finally, a unnatural solution should require an artificial solution. Now, I would like to dicuss how invasive species can cause destruction in enviroments that should…

Invasive species are classified as a species that inhabits an unknown ecosystem that isn’t unique to its personal features. Several invasive species have inhabited the Americas especially through bodies of water. One specific organism, the snakehead, is harming the ecosystem in large lakes and waterways. The scientific name for this species is Channa argus since it pertains to the Channidae family. Although, this species is most commonly referred to as ‘snakeheads.’ This organism was quite…

Invasive plant species pose a tremendous threat to natural resources throughout the United States. Invasive species can choke out acres of native vegetation and greatly reduce wildlife habitat. Invasive plant species threaten every aspect of ecosystem health and productivity on public and private lands, threaten biological diversity by causing population declines of native species, and alter key ecosystem processes like hydrology, nitrogen fixation, and fire regimes. Preventing, managing, and…

Invasive species have the potential to have a dramatic, negative impact on the areas that they invade. This can be observed in the harm that they cause to the environment and their impact on the health of humans and other animals. Arguably, invasive species cause the most damage by contributing to the loss of other species’ habitats. Many of the endangered plant and animal species found in the United States are in this position, in part, because of the impact of invasive species on their habitat…
