&gt;Of course, one day the population and our use of resources has to stop growing, but I doubt we&#x27;ll see it coming 100 years in advance.<p>I can&#x27;t speak to resource usage, but I think you&#x27;ll find  population models have the global population plateauing within the next 50-100 years. We aren&#x27;t talking about what&#x27;s going to happen in 2000 years here, that no one can be certain of. Your argument is like saying it&#x27;s rained and stormed for 2000 years why even try to predict the weather for the rest of the week? I hope you don&#x27;t mind, but I think I&#x27;ll still pay attention to the weather forecast even if it isn&#x27;t always 100% accurate.
