Though he refers here not to catastrophic environmental change, but instead to his own particular predicament, the observation of stranded astronaut Mark Watney of Andy Weir’s novel The Martian can well be applied to the former. The world-spanning threat of climate change will not be defeated, countered, or ameliorated by inaction, by wishing, by lying to ourselves about the facts, or by hiding our heads in the proverbial sand and pretending the problem doesn’t exist. It will require the limitless capabilities of the human mind to turn science and technology - the very things that have brought about environmental collapse - into tools for repairing or even reversing the damage.
