More than a few of you who read this, work in International Development. Poverty alleviation. The following words penned by American naturalist and farmer Henry Beston back in 1948 will not be a new idea to you:

“…man’s relation to Nature must never be anything else but an alliance.  ….When we begin to consider Nature as something to be robbed greedily like an unguarded treasure, or used as an enemy, we put ourselves, in thought, outside of Nature – of which we are inescapably a part. Be it storm and flood, hail and fire, or the yielding furrow and the fruitful plain, an alliance it is, and that alliance is a cornerstone of our true humanity.” (Northern Farm, Ballantine Books, pg. 29)

It goes without saying that humanity’s footprint on this planet was considerably smaller 400 years ago, when much of our current culture’s matrix was taking philosophical shape. So much smaller that most people did not think of Earth as a closed system. The resources of the planet seemed limitless (outside of concentrated population centers) and our ability to significantly harm our environment seemed miniscule in that vast land and seascape.

However, it turns out we’ve come to realize Earth is itself a closed system, as surely as the Apollo 13 moonshot. The same issues faced by Apollo -oxygen, CO2, and toxins – are precisely the issues we now realize our footprint is big enough to impact in dangerous ways.

One of the central, perennial conundrums for engineers who develop vehicles for space travel is the fact that a spaceship, (or space station, for that matter, even if it were the size of the Halo ring!), is a closed system – and how to keep humans alive in a closed system? A space capsule is utterly sealed: nothing gets in or out. So how do you not run out of enough good stuff (oxygen, water, food) and not build up far too much bad stuff (toxins like CO2 and human waste products)? The Apollo 13 crew nearly died because their CO2 scrubber broke.

Earth itself, we now see, is a spaceship, a closed system. We are absolutely capable of running out of resources. As I’ve observed before, you can monetize wood in your economy – but when there are no more cuttable forests, money is no longer exchangeable or translatable into wood. For us to continue to act as we did in the 1700s in regards to how we manage the planet, is insanity.

I was sitting some months ago at a wedding with a U.S. senator’s chief aide. We began to talk about this, and why environmental policy in Washington currently looks the way it does. I’ll tell that story next time.
