A person who has been punished is not less inclined to behave in a given way; at best, he learns how to avoid punishment.

Behavior used to be reinforced by great deprivation; if people weren't hungry, they wouldn't work. Now we are committed to feeding people whether they work or not. Nor is money as great a reinforcer as it once was. People no longer work for punitive reasons, yet our culture offers no new satisfactions.

The environment will continue to deteriorate until pollution practices are abandoned.
