If the sum total of humans living were individual cell members of a larger self aware organism, that being would see that its cells and organs were in very bad shape everywhere it looked. If it still had the stamina, it would seek to find a way to heal itself. It would try to salvage and nurse back to health the maximum number of cells possible. Once healed it would reorganize itself so that each cell's overriding function was to insure that the next cell thrived. It would continue to grow and and evolve creating ever newer more nurturing systems generating ever more rich and beneficial versions of itself.
