Poaching and smuggling are main causes of an animal becoming endangered. Pollution is very negative for an animal and its habitat. Animals are curious and try to eat the objects that are causing pollution. Also, some rivers and natural resources are becoming polluted and can make an animal have to move to a new home. Pollution harms valuable resources that animals need.
Normally, animals that are sick won’t show until there’s advanced disease because if they show they are sick in the wild, they would be easily caught by predators.3 The altered behavior is different for every species, and anim... ... middle of paper ... ....aza.org/health-husbandry-and-welfare/ 2.

Exposure to these drugs, chemicals, or diseases at certain levels can cause illness, pain, distress, and even death. Select tests can also require food and water deprivation to the animal. In order to test healing products, these subjects endure “infliction of wounds, burns and other injuries,” by www.his.org. When the study is concluded, animals are killed by carbon dioxide, neck-breaking, decapitation, or any other means. Even though these tests hurt animals, they also hurt the economy.

There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain. Many of the issues of biodiversity loss can be traced back to human interaction to the environment. One of the issues is alteration and loss of habitats. A lot of this issue is based on the destruction of habitats and for the land to be used for human consumption. The land is either used up for agricultural use or for neighborhoods.
These animals do not only threaten the Cozumel raccoons directly through predation and competition but also transmit disease and parasites, including mange, rabies, canine distemper and the parasite Toxoplasma gondii research suggest by Windscreen Arkive. (http://www.arkive.org/pygmy-raccoon/procyon-pygmaeus/) The reason of this is because “Cozumel carnivores have presumably been isolated from mainland para-sites and diseases for a long time, they may be particularly vulnerable to novel pathogens introduced by domestic animals and mainland wild species.” suggested by Biodiversity and Conservation (13: 317–331, 2004.) Also because of their small size they are much less able to defend themselves from predators. Other leading predators are the introduced Boa constrictor snakes, which has been well established in Cozumel Island and certainly capable of killing them and Northern Raccoons as pets brings further threats of disease and transmission and potential hybridization with the Cozumel raccoon. Therefore, introduced species have adverse effects on the life of raccoons.
