We, the People, have caused so much pain and disasters, the most time of our dwell on this beautiful planet. Since the Egypt and the slavery, the ancient Greece and the Persians, the crusifixion of Jesus, the exit of Columbus in South America,the revolution in France, to the WW 1 and 2 and more others before, during and after the examples i refer. Sometimes i am thinking that, Earth would be a better place if we had never been there. It might sounds rough, but it is just a thought and i believe that is very reasonable. We only get worse, despite the technological and the scientific progress.
