The human race is a horror.  We slaughter sharks by stripping them of their fins and dumping the rest of their bodies, still alive, to die in the ocean.  We tear apart the body of mother Earth to suck out the last drops of fossil fuels to feed our appetite for electricity and mobility.  We destroy habitat for innumerable species in every part of the planet, from mountains to rivers to forest, grasslands, reefs and the deep ocean.  If we disappeared from the planet tomorrow not a single place would suffer from our absence.  What can any of us do in restitution?  How can we as individuals learn to tread as lightly as possible on this miracle of a planet?
