Long term thinkers have the humility to realize that they cannot know all the different problems that will be faced by future generations, and that money that's wasted on one problem can't be used to solve another. So the long term thinkers don't waste resources trying to solve an unsolvable problem. Instead, they try to create as many resources as possible, and position those resources for flexibility so that future generations can solve any of the potential problems that they might encounter, one of which might include adapting to a changing climate (with or without man's influence).
