The choice, however, is as clear now for nations as it was once for the individual: peace or extinction.

True there has been more talk of peace since 1945 than, I should think, at any other time in history. At least we hear more and read more about it because man's words, for good or ill, can now so easily reach the millions.

I would like to end world hunger and create world peace, stop corruption, stop drugs getting to kids.

Peace without justice is tyranny.

When resources are degraded, we start competing for them, whether it is at the local level in Kenya, where we had tribal clashes over land and water, or at the global level, where we are fighting over water, oil, and minerals. So one way to promote peace is to promote sustainable management and equitable distribution of resources.
