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.
I reflected that the Derwent River might no longer exist and its beautiful ribbon-like pathway through our landscape might only be remembered in the fault lines of rearranged rocks.
Considering the geological and weather upheavals likely during those intervening years, I imagine the footsteps of human kind will not even be a distant memory. My guess is that the ant and cockroach populations will have mutated strangely and may be the only lively fauna roaming the planet. If water remains on the Earth then possibly some creatures who can survive in highly acid waters may be in the ascendancy in some regions.
It is rather strange to sit here tapping on my computer and to consider that not only do I expect the human race to become extinct, but all the artefacts of mankind will be obliterated over the millennia. Having held a career in the museology industry for much of my professional life, I retain the urge to collect and conserve the artefacts of our histories. Nevertheless, these collections and preservations will probably only be valued for a few more hundreds or thousands of years.
On this basis it seems that walking and discovering what we have around us is a much more worthwhile thing to do – at least at the personal level. In an earlier posting I referred followers to the blogsite of a man who took 11 years to walk around the world. Even if I should set myself a similarly outlandish goal, it won’t be possible now to walk from home to London in my lifetime except by using some water or air based technology to move from land to land. What a small dream this is in relation to the expanse of the history of the universe. But then, humans are not so great when compared to the scale of the universe.
