I feel like given the weather events we're seeing, that will continue to worsen, greed as a justification to destroy the habitability of our only world will be met with contempt once most have lost friends/relatives to the accompanying destruction/famines/droughts. No different than the highly profitable slave trade.

If we make it and find ways to mitigate or tolerate our new climate that will take millions of years to repair itself from what we've done in decades, we will likely be considered very backwater and primitive for doing it eyes wide open.
