Anyone who is seriously interested in me would usually do a little more homework and realise that the extreme criticisms are almost exclusively ideologically based.

The Prime Minister of India, at a meeting that I co-chaired a few months ago, stated that any development that is not sustainable is not development.

Either we reduce the world's population voluntarily or nature will do this for us, but brutally

We must, from here on in, all go down the same path... There may not be another chance.

So, what we do as individuals matters. It adds up.

What pleases me most is that sustainable development is on almost everybody's agenda now.

Inertia is a powerful force in human and political affairs.
