I recently watched a video that mentioned the “toxic pit problem” of how closed mines turn into toxic lakes full of rainwater and harmful chemicals. Some companies are trying to fix them, but I was wondering if the Earth could “purify” itself if left completely alone?
Like, let’s say all of humanity disappeared tomorrow, could the harmful chemicals be filtered out or dissolved or changed after a billion years?

It probably will just find a new equilibrium, allowing evolution to do it’s job, and life will go on.
