The portrayal of the earth as a cute anime girl to help pollution problems and to induce recycling. Its working. Everybody has their own personal earth chan "gf" some might say, that reflects what others call their carbon footprint. If you recycle and care about the environment, your earth chan feels affectionate towards you and likes being your gf, if you dont recycle and dont care about the environment, your earth chan gets sick and gets raped by "pollution".

Got the covid-19 vaccine

Must protect the not flat planet.

you will never look at Earth or nature the same way again

A weeaboo-made fictional character, portraying Earth as an anime character. Since it's not an actual anime character nor a product of Japan, it's considered a weeaboo thing. If you see someone posting an Earth-chan meme or cosplaying as her, you know they're a weeaboo.
