Thank you for your perspective. It is a shame that people are not mindful of their actions. Killing off a natural habitat in the quest for a mineral--the value of which is entirely subjective.
The commercialization of fish has wreaked havoc. I read about things like the collateral kill of a lot of fish caught in the nets when seeking sushi grade fish--it put me off sushi. Then there's shark fin soup in Asia, where they kill the shark to get the fin. It makes me want to cry.
The only good thing is, as you have pointed out, nature is very resilient up to a point. I just don't want to get to the point of no return.
