Calling all Walmart shoppers. The uber-giant big box store is hoping to bolster its green image by hosting an Earth Day Challenge for customers. With a theme of "Earth Day, Every Day" Walmart hopes to challenge schools around the country to enter to receive a $20,000 grant to further their school's green practices.

The program is meant to recognize schools and student bodies across the nation that are taking active strides to create a greener, healthier planet. Between April 3rd and May 1st, entrants can submit a 200-word essay on behalf of their school, showcasing their school's earth-friendly activities. Parents, teachers, and students are all eligible to enter. The only catch is that all entrants must be 18 years of age and they must be affiliated with the nominated school.
