ABSTRACT
The most dangerous threat to our global environment may not be the strategic threats themselves but rather our perception of them, for most people do not yet accept the fact that this crisis is extremely grave. Of course, there is always a degree of uncertainty about complex issues, and careful study is always necessary, but it is all too easy to exaggerate the uncertainty and overstudy the problem — and some people do just that — in order to avoid an uncomfortable conclusion. Still others are genuinely troubled that for all we do know about the environmental crisis, there is a great deal about it that we do not know.
