Would depletion of natural resources be so much of an issue if we could use fusion to recreate them? (after all, they didn't come into existence by magic...) Biodiversity is a bigger problem given the sheer levels of complexity and our relatively poor understanding of exactly how we depend on the exact make-up of the biosphere. Most likely humanity could survive without it, but it would be a poor sort of existence - our bodies and brains evolved in tandem with the huge diversity of life around us and is optimised to thrive in that context.
