Considering the volume of non-recyclable regular waste we produce as northerners, this actually look pretty small. Of course this soda can must be stored with more precaution than our other wastes. And we cannot just assume that future generations will be able to recycle all nuclear waste using futuristic engineering.
But from a practical standpoint it's seems, as of now, more easy to manage some precisely located wastes than to disseminate CO2 in vast quantity and expect that our kids can catch them using futuristic engineering.
