To make an animal endangered a lot of people have to contribute. Most of the time people cut down forests for farmland which destroys their habitat and the animals will be forced to find a new place to live. Animals can also be killed by introduced animals or poached by humans. It is bad to have endangered animals and everyone should try to stop killing them.
This depends on whether or not you are asking:
a) what are the environmental mechanisms that lead a species to being considered at risk of extinction or endangered? The above portion gives a brief idea of that;
b) what makes an animal endangered as determined by scientists? This usually involves various ways of measuring population and determining viable survival.
c) what makes an animal endangered as determined by the government and legislation that is supposed to be protective? For instance, Canada's Species At Risk Act or SARA puts species into 4 categories requiring different levels of action in order to protect their survival: Extirpated; Endangered; Threatened; and Special Concern. In this case, Endangered has a specific legal meaning.
Also, a species may be considered endangered by biologists but that does not always mean the government in question will recognize and protect that species as endangered because of other concerns, which are often political and economic. Current efforts in the United States to delist the Wolf and Steller's Sea Lion are good examples.
The organization that CLASSIFIES animals as endangered is the IUCN.
