A way of life that ever more rapidly depletes the power of the Earth to sustain it and piles up ever more insoluble problems for each succeeding generation can only be called violent.
E. F. SchumacherThe generosity of the Earth allows us to feed all mankind; we know enough about ecology to keep the Earth a healthy place; there is enough room on the Earth, and there are enough materials, so that everybody can have adequate shelter; we are quite competent enough to produce sufficient supplies of necessities so that no one need live in misery.
E. F. Schumacher
