That will never occur, fortunately. There is no end to the natural world. The natural resources that are most critical on Earth are infinite for all practical purposes in relation to human demands. This is especially true given the population growth curve for the next century. If we somehow exhaust the mineral deposits on Earth in the next few hundred years, we can and will mine the solar system. In the absolute worst case scenario, the rest of the natural world off of Earth is available for ruthless exploitation by our Capitalist ways for thousands and thousands of years to come. The clear bet is that it will be exploited eventually, probably by whatever we replace ourselves with.
