To take the concept that the world is maya, or illusion in another direction. If that's true, then why do we care if the world is warming or cooling, if oil is running out or we're finding more, if there are more tornado's, earthquakes, floods, etc.? They're no more real, just as much illusion, as the world itself or for that matter that we are.
Take oil for instance, practically speaking for thousands of years no one had ever heard of it, yet once a need arose, suddenly it was there, everywhere, oil wells, processing plants, many different products all from oil, almost overnight. As the world's need grew, more was found, in the 70's "They" were saying at the rate it was being used we'd run out any day, but the need continued to grow, and lately "They're" saying there's enough for one hundred or more years at the current rate of consumption. I believe we'll always have as much as we need, until there is no more need.
So what if the Mayans are right about the end of the age, the end of the world, the end of whatever, none of it is real. The illusion is going to continue to reflect the desires and needs of those who create it, even destruction, and nothing we do will change it until the dreamer(s) want, or need, it to change.
