Whether you're a nature-lover, conscious consumer, DIY aficionado, climate activist, or simply someone trying to live a sustainable life, Earth Day provides a reason to celebrate the planet. Though it can be fun to share a selfie, a cute animal, or a stunning landscape to your Instagram feed in honor of the holiday, capturing your gratitude for the planet in a short caption can leave you staring at your phone with your head in the clouds. Instead of worrying about thinking up the perfect Earth Day caption, take a deep breath, plant your feet on the ground, and use one of the captions ahead to show your witty, heartfelt, or action-driven love for planet Earth.
