THOUSAND CHALLENGES?

If we look at history of humans,you would observe one thing that they never faced as many challenges or we can say a threat to disturb their life as we are now facing in end of first decade of 21st century.
Global warming,TERRORISM,nuclear,biological and chemical threat,civil wars,increasing radicalization  of religious groups and the list keeps going on.
You will think that this all cannot wipe out humans.Yes of course not as humans are more adaptable than bacterias.BUT all these challenges have the capability to make the life of each and every human a HELL.We really need to do some thing as soon as possible
Do you really think that it is the job of OBAMA or he has the capability to put the things back to normal.Surely not.
SO,HOW WE GONNA FIGHT THE CHALLENGES?
WELL THE ANSWER IS YOU.
Its you whose efforts can bring change.I am talking about thousands of you who together are more powerful than Obama more decisive than any one else,your voice would be heard more than anyone else.
