However, he also urged cat owners to be more responsible.
50 year old Chris made his remarks to the Radio Times during a recent interview.
He said, “The deer population in the UK, many would argue, is way too great.
“We have to cull deer because there are no natural predators.
“We have to cull deer in this country, we have to cull elephants in Africa.
“We have to play a proactive role and that means killing things.
“People come to shoot near where I live and they ask me where the deer are and I tell them ‘the deer are over there, go and blast!’
“Because, frankly, I’m able to see the benefits of maintaining that population.”
On the subject of domestic cats, Packham said owners need to change their behaviour.
He said, “I don’t want to harm any cats. I don’t want to stop people keeping cats.
“But I pick up my dog poo, I run my dogs on a lead in certain places, I modify my behaviour.
“As a conservationist all I want to do is ask people who keep cats to move on in the way that they keep them.
“Over 200 million animals are killed each year by domestic cats. If you keep them in at night it reduces that figure by 50%.
“If you put one of these new electronic bleepers on them when they’re out during the daytime, it can reduce bird predation by 45%.
“If your cats are neutered then you haven’t got a surfeit of cats that aren’t being properly looked after.
“I love cats, I think they are beautiful, a wonderful predator.
“But what’s the point of feeding birds in the garden if you’re feeding them to your cat?”
Packham also defended his previous comments regarding his views on human over-population, when he proposed persuading people to have fewer children through the use of tax breaks.
He said, “We face horrendous hurdles in getting this message across.
“The first thing is the holocaust, because the minute you talk about this, people call you a eugenicist and they believe that you want to kill people.
“It’s such a nonsense. It’s not that there are too many whites, blacks, yellows, Muslims, Christians or anything. It’s organisms. Too many human organisms.”
