Did something for the tigers

Today i was in city center and saw some people roaming with a badge marked as "save our tigers"...i was wondering that whether they work for WWF or aircel?? but i thought why so many people of same office came there and were roaming as if they did not know each other..so i thought they were not any of the members of WWF or aircel..so i began to search what is this all about..after wondering some places in the mall i got to the main destination and i also got the badge and enrolled my name and my gf's also in the "roar"...e gave our thumb impression on a black and white tiger with  a yellowish saffron color..as if the thumb impressions would make the tiger as it's original color is...it was a great thing i think..many people had been already enrolled..i was quite hapy doing this..i wish i could do more.......
