Most Americans cannot imagine getting by with less, or that it could be an easier and more relaxed way of life while using less of our diminishing supply of resources. Our descendants will thank us if we do that. But it won't be easy, given the many changes in our ways of life that it will involve, and will benefit the environment too without the harm it would have done to our descendants without it, and also the more relaxed ways of life that we can live in the times ahead, rather than causing the collapse that we are moving toward now. The world is much too beautiful to risk that, as we are doing now. This is the subject that is being written about ever more frequently now, especially as the climate changes have become ever more damaging, with higher summer temperatures and winds, colder winter temperatures, and more extremes of all of them, and will become steadily more difficult to overcome, as has already become the case.
