Still, it seems there are things we can do, and must do, to slow the process.
We humans need to change profoundly the way we live. It will take a large cooperative effort, at the individual level and at government levels worldwide. We need to stop fighting wars and stop overconsuming the world's resources, to preserve its natural wonders and wildlife, so that our kids will have the opportunity to enjoy nature and, yes, caving. Humans are inventive. Let's work on it.
