...continued from Part 2
If watersheds become too badly damaged, polluted, or disturbed by things like dams or artificial tapping from industry, farming, or energy generation it can, and will, have enormous unforeseen impacts that could culminate in events like floods or large water bodies, like lakes, completely drying up! This is not just hypothetical, it has happened in the past like, for example, the devastating impact of Soviet "planning" that led to the loss of the Aral Sea - once the fourth largest lake in the world.
We all, every one of us, depend on healthy watersheds, consciously or otherwise, and so all have a vested interest in ensuring they remain clean, healthy, and sustainable. For this reason, the study of watersheds is a mission-critical activity and offers ways to not only maintain or rehabilitate them but also look for ways to potentially improve them too.
Pure, clean water is not just important today but, if some experts are to be believed, will become increasingly so in the future.
