If optimal health requires strict consumption of only sea-vegetables and coconut oil, one must offset the resources required their sustainable, scalable harvesting. If optimal health requires eating meat procured from animals eating only their native food sources in their native habitat, killed while their hunter whispers sweet nothings and severs their vertebrae at the nape with a swift, sure, and gentle strike, one must offset the costs required making the operation sustainable, scalable, and global warming-friendly - perhaps by inventing meat-vats, solving global warming, or discovering a means of feasible space colonisation.
