An '''endangered species''' is a population of an organism which is at risk of becoming extinct because it is either few in number, or threatened by changing environmental or predation parameters. |
Human beings are currently causing the greatest |
mass extinction of species since the extinction of |
the dinosaurs 65 million years ago. If present trends |
continue one half of all species of life on earth will |
be extinct in less than 100 years, as a result of |
habitat destruction, pollution, invasive species, |
and climate change. |
