Gary Opit is entitled to think what he likes about my opinions regarding the merits of battling extinction but he’s not entitled to make up facts.
When he says that extinctions are not normal he’s flying in the face of the evidence. Since life began on this planet billions of species have gone extinct, most of them before humans evolved.
Some of these extinctions resulted from catastrophic events, such as the asteroid-caused extinction of the dinosaurs along with many other species, while others occur naturally. Charles Darwin recognised this fact and coined the phrase natural selection to explain the phenomenon. By this Darwin meant than some species are better designed or adapted for their local environment than others and have greater reproductive success.
Under this concept species become extinct because they are out-competed by other species. Humans are excellent at changing the environment, which is certainly driving some species to extinction. In my view we should always try to minimise our effect on other species but in reality we can never reduce it to zero so we’re bound to cause some extinction; it’s part of the natural order and we should accept it as such.
