I've developed a huge regard for Toyota for its environmental awareness, for its immense commitment to research and development in this field, and for its leadership in developing hybrids which others are now following.

One of the things that I've always thought I would like to do is to develop an environmental index. Then people can measure their own environmental performance on an index as they do in other ways.

Ted Turner is still a leader. And he sets a great example. His ability financially has been reduced, but his influence and his example still is an important asset to the whole environmental movement.

Also, it is interesting that developing countries, with China and India perhaps in the lead, where the future of the global environment will be decided are now on board with the case for sustainable development.

We owe at least this much to future generations, from whom we have borrowed a fragile planet called Earth.
