Good on him! Certainly attracted a lot of idiotic comments below the article. One that sticks in mind is "I'd like to kill any human that kills animals". Any true observer of nature can see that animals that live in a synthetic environment, ie with their natural predators taken away, must be controlled by synthetic means.
I thought of a way to sort out population sizes once, just turn Everything off for a year or two, whoever's left after fending for themselves for all that time can then crack on. Survival of the fittest and all that. A bit extreme maybe, but it would save a lot of tax payers money! I might just jot that one down on a post it note and send it off to Chris and the UN!
