The Earthling is a serial comic strip currently appearing in the quarterly magazine “The Thinker” (Kangaeru Hito), published by Shinchosha publishing. The idea to personify the planet Earth into the central character came about when I was contemplating the issues of global warming. The comic strip at first appears to be about environmental issues but in fact is a nonsensical manga. The cast of characters include an earth hugger, tea stalk, fairy of dust (aka “dust angel”), an invisible dog, and a human plant. Read more stories at The Earthling - The Official website.
