Our planet is not as hospitable as we might like to think. Finding the right environment to live in may not be straightforward. Many parts of the world are not suitable for humans to survive in. The oceans are pretty much out for the majority of us. But so is much of the land area. We have mountain ranges where the terrain is difficult. There are Arctic areas which are too cold and desert lands which offer no water and high temperatures.
But if you were to guess what proportion of the land area on this planet is hospitable to us, what do you think the percentage might be? Is it 40%, 50% or 60% perhaps? The answer is a sobering 12%. And if we included the oceans as well, it drops to 4%. Food for thought as Climate Change begins to tighten its hold on us.
