Before conception, each of us had no claim upon the Earth. With conception and the miracle of new life, we laid claim to huge numbers of atoms. Energy put these atoms into molecules and kept them moving and accumulating such that our human bodies evolved. At full life, we include about 75 kilograms worth of these unique little particles.
Eventually though, and hopefully after a long and full life, our bodies can no longer sustain themselves. Death signals the end of a journey that started long ago from two cells coming together.
Not so many years ago, upon death, a human body would lie on the Earth’s surface. Where-ever it fell, it would provide food to a host of other creatures. Some carnivore scavengers may take advantage but most of the body would feed little creatures, the detrivores. And, these little creatures would fall prey to larger creatures that would fall prey to even larger creatures and, in a grand circle, may provide food and energy for a new generation of humans.
If we prevent the detrivores from accessing the human body, its potential as food isn’t realized. Further, if we bequeath even more to the body, we reduce the amount available for other living things, whether small detrivores or new generations of humans. This legacy can only come from those with little view to or hope of future’s potential.
