The sky and trees are the beauty of nature.It is the most intrinsic part of humanity. It is the art of God. Whether it's the morning sunrise or the moonlight in the night sky, everything roams around nature. Those who contemplate the beauty of the earth find reserves of strength to protect it. If you truly love nature, you will find a way to preserve it's beauty. As Carl Sagan said : We have to Preserve and Cherish the pale blue dot, as it's the only home we've ever known.
