The atmosphere has changed so people can`t breathe in it and there is no vegetation. The guy is driving a car when he sees this fallen tree trunk, stops and goes out to look at it. It turns out that in this changed atmosphere plants similar to underwater ones began to appear and thrive and so jellyfish swims easily in the new air. Thus a human is a relic of the past. New conditions - a new life!
It is a great honor for me that my image has become the cover of the November issue (146) of the Clarkesworld magazine.
