David Attenborough will be pleased as he has said the the earth is vastly over populated.There's a new programme on netflix, just started, pandemic. Scary stuff. When spanish flu hit in 1918, probably 50 million, and possibly as high as 100 million (three to five percent of Earth's population at the time) died. That's without the global flights we have now. They reckon it's will happen again, just a matter of when and it could wipe out 100's of millions.
