Abstract

Holocene=environmental stability, last 10,000 yrs. Planetary boundaries define safe operating space of humanity within the biosphere: climate change, rate of biodiversity loss, interference with nitrogen and phosphorus cycles, stratospheric ozone depletion, ocean acidification, global freshwater use, land overuse, atmospheric aerosol loading. Safe or at dangerous levels. We are past 3 and approaching 3. Species extinction is natural but is much accelerated 100-1000 times in the anthropocene era. Too much nitrogen causes overgrowth and pollution, anoxic conditions.
