How many square miles?

I do not know the area of land over which I have and will walk along the Derwent River.  And I do not care to find a definitive answer. That’s the sort of fact which doesn’t interest me.

However, I am fascinated to learn that there are 196,939,900 square miles of Earth to explore. So I made a slippery calculation – and determined there is less than 30 square miles per person on our planet.  Take out the area of deserts, and the too high mountains, and the number drops lower. The world’s population is growing rapidly so I strongly recommend you get out and walk your local beaches, parks, bushland, or sail the rivers and seas.  Enjoy these outdoor spaces while you can.

Almost two years ago I visited Hong Kong and walked the city streets with millions of locals in what was claimed to be the most densely populated suburb on earth. But even Hong Kong has thousands of acres of amazing parks, beaches and nature reserves all of which have walking trails in or around them.  All you have to do is to find your special natural places whether they are located in rural or urban areas.
