A specie can become extinct if it is over hunted, natural vegetation has been destroyed and if their homeland has been occupied or destroyed.
some one or something killed them off
White people hunting to much.
The bald eagle and the tiger are two animals saved from almost extinction
The two devices that assist in the prevention of extinction are: game reserves and lodges (frequently with hunting) and zoos.

competitive exclusion
Extinction is the permanent removal of a species which decreases bio-diversity. Bio-diversity is measured in two fashions # of species and # of members/species these two factors together make up a regions bio diversity, therefore with the removal of a species the regions bio-diversity decreases.
