I think this a huge point. Things in nature while robust and adaptable are still fragile. Take a freshwater lake and make it 5% salt and watch what happens. We have no idea what % could be the tipping point and we probably should try our best not to find out.

Edit, wrote this before seeing your post on tipping points.
