I've said this a zillion times before, if our population keeps growing, it does not matter what we do with respect to energy needs, pollution etc. we will be doomed. Babies born today may well die of starvation because the last fat rat has been eaten by the starving. I'm sure glad I am in my twilight years and have no kids/grandkids to worry over. As for the Zenith flying medical supplies in the UK, silly idea.
