Let us green the earth, restore the earth, heal the earth.

The most important issue of the 21st century will be the condition of the global environment.

We are the bullies of the earth: strong, foul, coarse, greedy, careless, indifferent to others, laying waste as we proceed, leaving wounds, welts, lesions, suppurations on the earth body, increasingly engulfed by our own ordure and, finally, abysmally ignorant of the way the world works, crowing our superiority over all life.
