April marks the beginning of spring in the northern hemisphere, and the season's renewed growth and energy serve as a reminder of the importance of protecting our planet and its natural resources. To promote environmental awareness and action, several significant environmental observances are celebrated in April, including Earth Day, Arbor Day, and National Parks Week. Celebrate with Ekstrom by exploring a book about sustainability and taking steps toward positive change. Let us all do our part to protect the planet and make a difference.
