I don't know where you got those notions from, but since a lot of people recycle copper I don't think we're going to run out of it, much less in six years. Helium I have no idea about, but that'd suck for all the kids' birthday parties that depend on balloons. AFAIK there's no substitute for helium.
Recycling is in no way as far as most people wish it'd be. No reason to be alarmed but its a scenario where countries could go to war over.
