Earth Day is an annual celebration that honors the progress environmental movements have made in protecting our natural world. It's also the perfect time to engage with nature more deeply, and to learn about current issues affecting the environment today. 

This year's Earth Day theme is "Invest In Our Planet." As you browse the resources in this display, consider the ways in which you as a citizen, as well as large organizations like businesses and governments make investments in the planet's environmental health.
