i think our planet earth is beautiful. The natural beauty which this planet has is simply awesome. We should make every effort to conserve and protect our planet,take precautions to protect our environment and nature so that it remains beautiful forever. Further,human beings inhabiting the earth are beautiful too especially the female species :)
Jokes apart, beauty is internal and not just superficial. Ones' traits makes one beautiful or ugly.Beauty lies in the eyes of the beholder.
