R.I.P. Gerald Durrell, a true conservationist
One of the most sincere conservationists I like the most is Gerald Malcolm Durrell, OBE (1925 — 1995) who wrote number of books on animals and nature and founded ‘Gerald Durrell Trust’ & ‘Jersey Zoo’, a haven for most of the endangered species of animals!
These days being a conservationist is a very risky affair because greedy people who pollute our planet just to make some extra money do not like any conservationist coming in their way, and so to stop any conservationist, they go to the extent of killing him/her.
There are different types of conservationists: wildlife conservationists, agriculture conservationists, land conservationists, water conservationists, marine conservationist, library conservationist, and so on.
