q1
An endangered species is a population of an organism (usually a taxonomic species), which because it is either (a) few in number or (b) threatened by changing environmental or predation parameters, is at risk of becoming extinct. Many countries have laws offering special protection to these species or their habitats: for example, forbidding hunting, restricting land development or creating preserves. Only a few of the many endangered species actually make it to the lists and obtain legal protection. Many more species become extinct, or potentially will become extinct, without gaining public notice.
