We do know with reasonable certainty that life is adaptable and likely to survive any man made catastrophe: as humans go extinct if they don't do much to prevent their effects on the ecosystem, Earth and life will likely find a new equillibrium for the mid-term future (millions of years). But we are worried about short term future that directly affects the human species, and even knowing what environment we'd be living in for that short term (thousands of years). If humans want to go past those thousands of years, or tens of thousands of years, it seems some change of behaviour is needed, and a better understanding of the inter-relations between species.
