Without significant effort, we are not so good at a judging what resources that are not essential now yet will be in the future. Even the example, I'm going to give is lacking because it is rooted in today's technological activities. For example, how would the stuff left on Everest affect the remote sensing requirements of the future? Perhaps there is more, but we cannot have thoughts about the questions we do not know to how to ask yet. This view point should not be straw-maned as objecting to any and everything, it is simply cautionary. In summary, in coming to conclusions we have to factor in our lack of sufficient imagination.
