  3. What is an endangered species? • An endangered species is a species whose numbers are so small that it is at risk of extinction. • Extinction is directly related to a species being endangered if the problem is not fixed. http://wordnetweb.princeton.edu/perl/webwn?s=endangered%20species

  4. Extinction • The rapid loss of species we are seeing today is estimated by experts to be between 1,000 and 10,000 times higher than the natural extinction rate. • means the rate of species extinctions that would occur if humans were not around • experts calculate that between 0.01% and 0.1% of all species will become extinct each year • 2 million different species on our planet: between 200 and 2,000 extinctions occur every year • 100 million different species on our planet: between 10,000 and 100,000 extinctions occur every year http://worldwildlife.org/
