Planet Earth has always operated within limits–almost like an organism. But too there have been “accidents” that overwhelmed natural processes and created eons of disorder.
Runaway climate shifts of the past carried the land or sea beyond a state where life-as-usual could go on. Volcanoes erupted, continents smashed together, or a stray meteorite created a “nuclear winter” that set the state of living things back a few hundred million years.
But for the most part, long stable periods on Earth have been adequate to allow species to diverge and disperse, biomes like coral reefs and prairie and tundra toÂ develop and forests to reach climax stability–what we would call OLD GROWTH forests today. It is almost non-existent in our times.
And for the first time in Earth’s history, we are thinking about the factÂ that our one species can perturb conditions in the air, soil and water sufficient to push natural resilience to and past the breaking point. And so there is growing talk about Planetary Boundaries.
Of note in the diagram, the light green is AGRICULTURE’s part in pushing the limits. Note for how many of these 9 boundaries land-care (the literal meaning of agri-culture) is a contributor.
We must change the way we wage war on the landscape, and begin to think intentionally about how we relate to and contribute to the well-being or dis-ease of the land. Margaret Meade said it well:
We won’t have a society if we destroy the environment.
And yet in our arrogance and ignorance we act as if we can push the limits–beyond the breaking point; beyond tolerance; beyond carrying capacity. Somehow our engineers and technological wizards will find a way, just in the nick of time, to cheatÂ the odds so that we do not become yet another once-great civilization on the dust heap of environmental failures that have gone before us.
I will be looking a this soon–on February 11 at 2pm at the Floyd library. Topic will be “Living in Our Forests: From Ice Age to Anthropocene. Barbara Pleasant and Jane Cundiff will also have boots-on-the-ground information to share, along with this thirty-thousand-foot view of things.
This bit of it just bubbled up as I was looking back at my notes. Morning pages, you know.
