The Slow Loris appears on the IUCN Red List as an endangered species. An all to familiar story. Throughout history, numerous species have become extinct. This is nothing new.
The Dodo became extinct because it was a docile tasty bird that could not fly. Thus providing mankind with a handy snack in the absence of fast food restaurants.
Animal rights activists would have you believe that this was a bad thing. However, nature evolves to allow new animals to flourish in the absence of others. Had they been present at the time, would they have been campaigning for the survival of the velociraptor? Surely the existence of mankind is also part of nature's rich tapestry.
So back to the Slow Loris. Perhaps it is part of the grand design that they should also fall by the wayside. I think the clue is in the name. There is no Fast Loris on the IUCN Red List.
