There are a LOT more than three here. If you need this for an assignment or whatever, pick the best three. # Habitat loss/destruction. If an animal's ecosystem (including the place where it lives, its relationships with predators and prey) breaks down and changes faster than it can adapt, it will die out. # Predation. If a new predator enters an ecosystem (usually a species introduced by humans) that the animal cannot defend itself against, it will be eaten out. # Hunting by humans. If an animal is intentionally sought and killed by humans as a pest, food animal or for novelty (ie elephants for tusks, tigers for pelts) and more are killed than the reproduction rate replaces the animal will become extinct. # Disease. If a new disease or mutation of an existing disease occurs that the animal has no immunity to, this can quickly sweep through and destroy a population. # Isolation. If the pockets of habitat where that animal can live are too small, the populations in any one place will be tiny. This makes them very fragile because they can easily be wiped out by disease, predators, a natural disaster etc. Also, isolated population pockets become inbred resulting in a far greater occurence of stillbirth and deformed young that do not survive. # Extreme conditions. An example would be a grazer's ecosystem being gripped by a drought. The grass will die and the animal will starve. These usually happen so fast that the population has no time to adapt to them. # Natural disasters. If a species' population is spread over a small area which is destroyed by a natural disaster, it has a fair chance of dying out.
we hunt for a paticular thing that the animal has, we pollut; so heaps of turtles are dieing because they have eaten plastic bags or choaked on little things, we also cut down their habatat so they have no where to live.

Nothing, humans are a species of animal.
the definition of endangered species is species who are close to extinction, or dying out; in the risk of extinction this is my personal definitionWhen an animals numbers become too low to sustain a viable population, it becomes an endangered species.
Endangered species
It frees up ecological niches for other species.
Extinction refers to complete eradication of a species such as the Warrah or Dinosaurs (things that no longer exist), whereas an endangered species is merely under threat of eventual extinction, but is not there yet, like a panda or a California Condor.
Using renewable resources, recycling, and reducing pollution are three things that can be done to prevent premature extinction of the worlds existing species from human activities. Enact new laws to prevent species extinction can also help.
Humans are mammals, a type of animal. We Humans are animals, for the fact that we are innatly evil, greedy, and hateful. We are the only species that constantly kills our own, especially over things that means nothing.

endangered species
because of the interdependence of living things The extinction of one species or development of a new one often affect many others because of their interdependence in an ecosystem.
an endangered species
If the food web is disturbed species above will suffer. the species above will not have as much food so their numbers will slowly decrease. Also the species will become ill.
