My sister is a bit of a tree hugger at heart. You know how people who trek to a foreign country sometimes come home obsessed, wearing the clothes, eating the food, and sprinkling their speech with words from the place they visited? My sister says that’s how she’ll be if she makes it to heaven one day, sporting an Earth t-shirt and endlessly saying “Remember Earth? Wow, that place was so amazing.” Every Earth Day, I can count on her to share the most beautiful naturalist quotes and the most heart-stopping photos of landscapes. By the time her kids learned to walk, they learned to hike, and to pick up litter along the way! I’m grateful for my sister’s example of loving and showing gratitude for this stunning planet. Among all the miracles of nature, there’s nothing that beats a great sister.
