Tardigrades, commonly called water bears, are eight-legged microscopic animals. They are among the most resilient lifeforms on Earth. They can survive massive doses of radiation, pressure that exceeds that of the deepest ocean trenches, years of dehydration, and a temperature range of minus 200 Celsius to 149 Celsius. Low Earth orbit experiments have demonstrated that some species of tardigrade can survive for days while exposed to the vacuum of space.
Despite our best efforts, humans could never destroy the Earth enough to render the tardigrade extinct. Perhaps at some point in the distant future, some highly evolved descendant of the tardigrade will happen upon our ruined civilization and tsk-tsk us for our recklessness.
