This photo was taken during a trip that I made to Perú. Something important that I have learned from ancient civilizations is that we must take care the place we live in. Here we can see Urubamba river passing thruogh the Sacred Valley in Machu Picchu. Incas were close to nature. They took care of the environment and our mother earth. They had a so different view of the world than our society has today. Nowadays it seems like if we do not care about the damage we are cousing to our planet.
