Sagittarius people fancy maintaining a healthy and active lifestyle. Besides, as a Sagittarian, you are an outdoorsman and an adventurer. Thus, the best way to celebrate Earth Day for you is to go hiking! A hike is the best way to get rid of the bonds of your urban life and to enjoy the beauty of the world.
If hiking is not the thing for you, then do take a long walk in the park or in the forest where tall trees cast fanciful shadows on the ground and birds sing sitting upon the boughs. This will help your recover your equanimity and relax. Be sure to take bottled water with you but note that plastic litter doesn’t biodegrade!
