Earth Day is this Sunday, April 22nd. This day was established in 1970 to increase awareness of environmental issues and inspire conservancy. If you want to celebrate in Memphis, there will be an all-day event at Shelby Farms Park this Saturday. The Memphis Zoo is also hosting a celebration on April 25th focusing on endangered species. The zoo's website has all the scoop on this Party for the Planet. And you can celebrate all month long at the Memphis Botanic Garden. Their goal is to incorporate green themes into several events promoting smarter choices for the environment. Their calendar is online.
