My Personal island\Planet
Here's an interesting sum to do
Take the Earths surface area 510 Million sqkm divided by 7 Billion peple gives about 72,857 sqm each,
Which allowing for 70/30 split sea\land gives each of us an island about 167 m dia surrounded by a donut of sea 67 m wide..
And we haven't even allowed for mountains deserts, ice and other "uninhbitable\non-productive" land which eats into our share
Just to complete the picture if the atmosphere wasn't squidgy and was the same density from ground to space it would be about 8km or 5miles thick.
Good news is there's plenty of water cos the average sea level depth is nearly 4km
Now for the final twist population growth is about a million people every four days, which to give the newcomers an equal and fair share means my personal island (land area only) is dissapearing at the rate of about 0.78 sqm a day
or in old money just under a square inch a minute all day every day..
