Abstract or Description
Who can dispute the conception of "spaceship earth?" Materials are not consumed or destroyed, man merely changes their location and form. Our air, water, and land have an incredible capacity to absorb these changed materials, hut their capacity is not limitless. At some point we will have to change our viewpoint from that of correcting isolated excesses to worrying about the forms of all released "residuals."
