? What does #EarthDay mean to me? How about the continued ability to travel the world, climb volcanic craters, and enjoy views like these, without highly acidic oceans, bleached coral reefs, and inundated coastal cities lying in ruin? Or, maybe it means leveraging the power of renewable energy sources and living a fully sustainable lifestyle because I'm a decent, non-selfish human being who is acutely aware of humanity's dependence on its only planetary home? Or, how about the awesome Earth Day workout badge on my Apple Watch today? TAKE YOUR PICK!
