The environmental crisis is a sign that the ecosphere is now so heavily strained that its continued stability is threatened. It is a warning that we must discover the source of this suicidal drive and master it before it destroys the environment-and ourselves.

In certain ways, I'm not very different than I was when I was a teenager.

What is needed now is a transformation of the major systems of production more profound than even the sweeping post-World War II changes in production technology.

The modern assault on the environment began about 50 years ago, during and immediately after World War II.

The environmental crisis is somber evidence of an insidious fraud hidden in the vaunted productivity and wealth of modern, technology-based society. This wealth has been gained by rapid short-term exploitation of the environmental system, but it has blindly accumulated a debt to nature-a debt so large and so pervasive that in the next generation it may, if unpaid, wipe out most of the wealth it has gained us.

If you ask what you are going to do about global warming, the only rational answer is to change the way in which we do transportation, energy production, agriculture and a good deal of manufacturing. The problem originates in human activity in the form of the production of goods.

Perhaps one of the most meaningful ways to sense the impact of the environmental crisis is to confront the question which is always asked about Lake Erie: how can we restore it? I believe the only valid answer is that no one knows. For it should be clear that even if overnight all of the pollutants now pouring into Lake Erie were stopped, there would still remain the problem of the accumulated mass of pollutants in the lake bottom.
