Since its inception in 1970, Earth Day marks a global celebration of Earth and the concept of peace. It presents an opportunity to demonstrate support for environmental protection. From lush rain forests to arid deserts, thundering waterfalls to serene ponds, majestic glaciers to craggy mountains and teeming coral reefs, Earth is a complex, interconnected planet, filled with diversity and abundance. New species continue to be discovered, and the relationships among species and ecosystems are increasingly revealed in our understanding as intricate and inextricably linked. To be tenants of Planet Earth is a cause for gratitude, but we also have responsibilities to maintain and protect our planet for each other and for future generations. In this Spotlight on Earth Day, we take a look back at prior DailyGood features and offer some suggestions of how you can support and celebrate this planet we all call home.
