It's all the fault of consumers in the West, probably.

I am sure that population control is the hardest of nuts to crack for any government , and China ought to be congratulated for having done this. Contrast that with India , where there is no control , and no political will to control. 90% of the problems with india originate in its ovrpopulation.

Don't worry - Our UK Labour Govt will charge us all (in the UK) with a super duper new Green tax and the whole world will be saved! Super Gordon, how about doubling Tax on fuel, that will work. Why didn't every town plant 2,000 trees each for the millenium, instead of the rubbish they built, etc.

have you thought that sterilization will mean that a whole generation and possibly 2 or more will be wiped out and only old people will exist. Which is even more of depressing future. What are yougoing to do when all the 60 year olds want to retire.maybe china have the answer.

It looks like we are all too late , it has happened already.

@Bill in the US and Jim Wills in Australia,
since you diagnosed the problem so well, I suggest you begin by volunteering yourself to get sterilized first...it might set a convincing example?

It is not entirely to do with population growth but more to do with mis-management and political corruption which allows loggers and the big boys to snatch and grab. China is the culprit at the moment, but there have been many bad colonials before. Africa seems like a continent for endless pillage.

In my opinion, sterilization might help but how do we enforce this?
Government policies on birth control should be enforced whereby a must not be allowed to have more than two children especially in Africa and Asia.

Conventional warfare doesn't help at all. Birth rates just rise; even WW1 was more than compensated for in a couple of decades.

It's ironic that, in spite of our vaunted intelligence, homo sapiens can't organize itself well enough to avoid breeding itself to extinction.

Shocking! We work with conservationists who blog about progress and challenges in projects across the continent. To follow the fate of gorillas in threatened forests or lions in he Masai Mara, and to learn about the lives of conservationists a the front lines, go to http://wildlifedirect.org

The major issue behind most of the global problems we come across these days is Popluation Growth. Unless something is done to reduce this then the human race will slowly destroy itself over a period of time. How about the rest of the world adopting the Chinese approach to population control?

Paul Watson, Choley, England

Colonialism didn't help either !!!!

ian payne, walsall,

We should have more conventional warfare. Dying in battle is the most honourable way to die. Unfortunately, modern warfare tends to be incredibly destructive to the environment, even conventional warfare. Perhaps the question is how we can make modern warfare more sustainable and eco-friendly? ;)

For years i have said the mankind is breeding itself
out of existence.
And for years I feel that I have been yelling into the
wind.
There is a partial answer and that is for all countries
to impose a very large tax on large breeders. To a point
no one will want to churn out children.

Jerry Scroggin, Phoenix, Arizona/USA

The only way to save mankind is to force steriliztion. The USA and the rest of the world is too greedy to want to do this, then there are the right to life nuts. There is no hope, we will destroy our planet, the only one we have.

Bill, Stuart, US

OK!. So we have the evidence that population is the problem in this case. What are the governments of the world going to do about it?. Noting I guess but talk. A good start would be to reduce the population growth by sterilization programs there and in every other country on the planet.
