Earth Day
Earth Day is a global environmental observance held every April 22nd, first organized in 1970 by U.S. Senator Gaylord Nelson and activist Denis Hayes. Online it's best known for Google's 2015 animal-matching Doodle quiz and the meme parodies that followed.
Overview
Earth Day is an annual event on April 22nd focused on environmental protection and conservation, coordinated by the Earth Day Network2. The 1970 debut pulled in participants from over 2,000 U.S. universities and 10,000 schools, and the observance later grew into one of the largest secular holidays in the world, with more than a billion people taking part each year3.
The holiday itself predates the web, but Earth Day's clearest crossover into internet culture came from a Google Doodle in 20151. The interactive quiz let users answer questions to be matched with one of twelve animals, including the pangolin, sea otter, honey bee, cuttlefish, and coral3. Google's Doodle program had been running since 1998 and expanded to same-day topical events by 2009, which is why an environmental quiz on April 22nd fit the format so easily1.

How to Use This Meme
Online riffs typically follow two patterns. The 2015 Google Doodle spawned a template where users post which of the twelve animals they got matched with, often paired with a joke about how the pairing fits (or doesn't fit) their personality3. Separately, sarcastic posts about performative Earth Day rituals, like ceremonially unplugging appliances or biking one day a year, show up around April 22nd in the vein of the older Urban Dictionary jokes5.
