I am juz had a thoughtwhen i am viewing a movie which is around 1970s. And to the fact there are a few scenes about pollution and its effects on the Earth. How great these humans spoil the only liveable planet(as far as we know from space research) in the universe.
So I am writing what once there at earth, 25yrs before my birth and what is left 25 years after my birth rigth now.
What had changed according to me over the 50 decades:
Avarage Human living period decreased.
Now people start smoking,Drinking at a earlier age compared to people lived at 50yrs back.
Oh my god our protection shield ozone layer is been having huge holes.
We are getting a chance to see is there only ice or some landscapes at north and south poles.Ice is melting more than normal.
Now most women are thin(for modeling) or Fatty(unable to control the desire to eat) and the human reproductions started having a severe effect.
Pass on this message and make sure it is circulating in a speed equal to our blood in veins and shake the people(like P.M and Presidents) who can change these things.
