Colonisation and industrial revolution have reduced the harm? For whom?

Looking it from a white, western male perspective, you're right. From other perspectives this might well not be the case.

A lot of technology has short term benefits but are, in the long term, net negative to either us as species or the environment around us - which is the life support system for us. We as a society have not got a "undo" button for much of this technology, since once the damage has been done in real life, it stays in real life.

So we develop technology, see it fail, and try to fix the issues with more technology not realising that technology might be the problem. Or perhaps it's because we don't have the simplicity of an "undo" button.
