You live in the three dimensions of space, where water and air and land fill up the space and bear a few things for you to live on....for a while. Do not forget this environment also has the dimension of time, past and future.
If the only way you care to meet your needs is to steal from the future, you should do without or think up a better solution.
If doing without means you will parish, so what? You had no future anyway. ( Or do you believe that you were meant to be of the last generations of men?)
