We Have The Power

“Over billions of years, on a unique sphere, chance has painted a thin covering of life – complex, improbable, wonderful and fragile.  Suddenly we humans (a recently arrived species no longer subject to the checks and balances inherent in nature), have grown in population, technology, and intelligence to a position of terrible power: we now wield the paintbrush.” ~ Paul MacCready

10,000 years ago human population plus livestock and pets was approximately 0.1% of vertebrate biomass.  Today it is 98%.
