Earth Day memes encompass a wide range of internet humor, from wholesome appreciation of nature to biting satire regarding corporate greenwashing and individual hypocrisy. While Earth Day itself was established in 1970 to support environmental protection, the digital age has transformed the holiday into a prime time for viral content. Common tropes include the contrast between how people act on April 22nd versus the rest of the year, or personifying the planet as a tired character dealing with humanity's antics. These memes serve as a powerful tool for climate activism, using relatability and humor to spread awareness about global warming and conservation in an accessible way.
