When spending time outdoors, whether it be hiking, camping, or whatever, the only thing you should be taking home with you is what you had with you when you arrived. You should not be picking up rocks, taking home starfish, or collecting anything that is found in nature. Sure, it may seem like a tiny amount to you right then and there – but multiply that tiny little bit by the millions of people on earth. If we all did it, there wouldn’t be anything left. So when you spend time outside, bring your camera and take pictures of the things you find interesting. Nature, and the rest of us, will thank you for it.
