Following up on the previous chapter focusing on human-caused resource depletion [4], the other disheartening part of the story of the environment concerns the things we humans put back into it, and the impact they have on the ecosystems that support all of life -- ours included.
Like the economy, ecosystems are complex systems. That means that they owe their complexity and order to energy flows and, most importantly, they are inherently unpredictable. How they will respond to the change by a thousand rapid insults is unknown and literally unknowable.
Like any complex system, an ecosystem will tend to remain in a stable form until the pressures become too great and then they will suddenly shift to a different baseline and exist there for a while. That is, instead of having some magical preferred equilibrium, they have many -- and some of those will be decidedly less or more awesome for humans to exist within.
If the world tips from a stable climate to a less stable one, as it has done many times in the past, then growing enough food for everyone will become difficult if not impossible.
An ocean acidified will remain that way for possibly hundreds of thousands or even millions of years. Overly-depleted cod fisheries will take many decades to recover, if and only if they are not fished in between. A species wiped out remains that way forever.
An overpumped aquifer may take thousands if not tens of thousands of years to recharge.
There are a hundred flashing red warning signs coming to us from the environment, the Earth, and all of its supporting ecosystems. Either we get off the 'growth at any cost' express train or we risk wrecking important, valuable, essential and beautiful species, ecosystems and support systems that we rely upon for our health, our wealth, and our happiness.
Once again, you and I do not have any particular need for constant exponential economic growth. It is only our money system that has that demand.
Either we figure out a way to live on our own terms or we'll simply default into doing the things that our money system demands of us. The former has a possible future; the latter does not.
