Our being is silent, but our existence is noisy. Yet when our noisy actions stop, there is a ground of silence always there. Contemplatives must be in contact with that ground and communicate from that level to keep silence alive for other people.
The need is for the connection to nature within ourselves; only then can we understand how to act toward nature outside ourselves. Along with the obvious crimes our culture is committing against the natural world, we would be wise to remember that the main crimes are the crimes against our inner nature. From these inner crimes all the outer evil arises. This is the teaching of wisdom.
