"The threat of nuclear weapons and man's ability to destroy the environment are really alarming. And yet there are other almost imperceptible changes - I am thinking of the exhaustion of our natural resources, and especially of soil erosion - and these are perhaps more dangerous still, because once we begin to feel their repercussions it will be too late."
p144 of The Dalai Lama's Little Book of Inner Peace: 2002, Element Books, London)
Which is more important? The answer depends on the type of erosion, where it occurs, and on many other factors.
