"The thing the ecologically illiterate don’t realize about an ecosystem is that it’s a system. A system!
A system maintains a certain fluid stability that can be destroyed by a misstep in just one niche.
A system has order, a flowing from point to point. If something dams the flow, order collapses.
The untrained might miss that collapse until it was too late.
That’s why the highest function of ecology is the understanding of consequences.”
