20 years before when we were about to enter 2000 there were lots of hypothesis and it was all about zero zero zero. Nothing happened. when we were about to enter 2020 there were no assumption about the year 2020. Our world is no more the word it was before. Our planet earth sends us a message that she can no longer accept the human behaviors, they exceeded the limit. So the earth decided to go to the safe mode. If we cannot change our self most probably the earth will go to deep sleep mode!
