Throughout human history, man has pondered the purpose and meaning of life. Endowed with a large brain, we have convinced ourselves that the ecosystems of planet Earth were created for our benefit and human cultures have imagined a wide range of gods that facilitate and govern that process. The fact that life evolved almost 3.6 billion years before our own species appeared is ignored or rejected by most religious persons; after all, they believe that this earth-bound life is preparation for a more significant, eternal existence.
If we strip away the cloud of human mysticism, we find that life has the single purpose of sustaining itself and has "learned" that diversification is the best means to accomplish that goal. In the words of that thoughtful scientist in the film Jurassic Park, "life will find a way."
Unfortunately, the mysticism of human society often impedes the purpose of life, as religious and sectarian wars decimate populations and as the culture of human superiority encourages the exploitation of our natural resources. If we truly support the purpose of life, we humans need to end our futile conflicts, devote ourselves to protecting the natural diversity of this planet and ensure that our own unbridled population growth does not threaten the sustainability of Earth's ecosystems.
