"We are in a period of ecological collapse right now, the consequence of habitat and species loss partly attributable to climate change and partly to the destructive activities of Homo sapiens (which in turn accelerate climate change). The predictions for future extinctions in our time are dire for both animals and plants – and perhaps for man himself, since man cannot escape the fate of the natural world, no matter how much he believes he can; like it or not, he remains part of the global ecosystem. It may be that in the long term the universe is implacably hostile to all life anyway. It may be that our planet and all its cargo are proceeding towards eventual extinction. It may be that in the shorter term all life proceeds according to the laws of evolution, through successive stages of extinction (from whatever causes) to universal oblivion. But as Gerald Durrell constantly reiterated throughout his adult life, that does not mean a man can stand idly by and watch it all happen without lifting a finger. With the millennium, perhaps, we will enter an age of ethics. Man can learn, as Gerald Durrell frequently pointed out; man can come to his senses, can change, can try to save the day. And thanks to the inspiration of people like him there are signs that, at the eleventh hour, this is beginning to happen; that we may one day hope to turn the tide of habitat-destruction and man-made extinction on earth. That was Gerald Durrell’s message, and that was Gerald Durrell’s life mission. That message and that mission will be carried forward by those who succeed him."
