We have a Safari park 30 miles away where you can drive through in your car amongst African animals roaming free.
In a seperate enclosure they have various monkeys, gibbons, apes etc.,
About twenty years ago I had a request from the Safari Park to supply cartridges loaded with Rice.
These were shot at the monkeys to stop them copulating infront of the public.
Ten years later all the monkeys had gone, wiped out by an Aids virus. Never for the monkeys to be replaced.
