Usually, when I go trekking in our beautiful mountains, when I go down from the top of mountain, I pick up rubbish which is left by tourists along the path. I don't understand, why people enjoy the beauty of nature, but throw rubbish there. 🤷🏻♀️ I think, I pick up rubbish on my way down, it's not only for leaving place beautiful, I protect our forests, mountains from fire, and animals won't eat rubbish.
