Natural speed please; male voice please
This is silly! Our limit is only from our imagination. Our resources are increasing as long as new technology improves efficiency. For example, new technology helps extract resources from deposits before unavailable. How many species are created every 100 years? Humanity has introduced new plants and animals. Why must every discussion talk about what we've lost, and not about what we have gained? If you truly believe in Darwin, then you must accept change in our flora and fauna, not assume things should be static.
