Close your eyes. Imagine a world where you are the main character. Your every step determines the future of the World and your every decision transforms the environment.
Forests delight with greenery, because you planted and protected them. Birds sing loudly, because you did not let them die. Air is clean and fresh, because you did not allow it to be polluted. You can drink from rivers because you have taken care of their cleanliness. Your inner world is beautiful, isn't it? Would you like to stay?
Open your eyes. This is your World. You are the main character. The future of the World depends on you, just as you depend on it. You save nature and nature saves you.
