This photo represents the complexity of life. Every brand on this tree displays a different issue/situation of in our world. The blue sky and ocean represent the vast universe where it is very difficult to identify all the detail and diversity out there. To use, the universe is vast with many planets, but who knows how many more planets out there which have creatures like us humans living on there. It is crazy to think about all the unknown which we may never discover in our lifetime. The tree appears simple as a whole picture, but if we zoom in, there are trillions of different things which we can't see. On this tree, there is a possibility of living creatures which are invisible to the naked eye which have not been discovered yet. It may sound impossible, but there is always a possibility of finding new things.
