I think that was the point during the age of the dinosaurs and wooly mammoths. Creatures that just mucked around...cluelessly...and accepted whatever fate befell them.
But, we've evolved to the point of being able to not only be aware of the phenomenum but, to be able to quantify it and act on it. Even the liberal arts majors, with their naive, tree-hugging philosophy at least get the concept, if not the science
To me, the point is to go after it aggressively. If the ultimate result is failure and extinction...well...in the dying gasp of the last human, he/she can at least proudly say, "We gave it our best shot".
