Why will Adah Sharma lock herself behind bars?

People have their own way to take up a cause and actress Adah Sharma of films like 1920 and Phhir is planning to lock herself behind bars to urge people to let birds fly free. She is going to dress in white attire to resemble a bird and will peer through bars while being locked up in a cage and holding a sign that reads, 'Let Birds Fly Free. Don’t Cage Them’, for PETA’s latest campaign in a restaurant in Bandra.
Adah says birds were born to be free and that locking them in cages and denying them that freedom and the opportunity to fly is cruel. “Birds want their freedom just like we do, they want to spread their wings and reach for the sky”, says Sharma. "When they are caged, smart, chirpy birds become depressed and withdrawn. Loving birds doesn't mean you’ll cage them, rather enjoy seeing them play and fly free in nature, where they belong.”
When birds are caged, they are said to become depressed and withdrawn. They often over-preen themselves to the point of mutilation. Some people force birds to endure wing-clipping so that the animals cannot fly away, yet flying is as natural and as important to birds as walking is to humans. When birds are captured and packed into small boxes for shipping, many suffer and die in transit, usually from broken wings and legs, dehydration, starvation and stress. Keeping birds in cages is both cruel and illegal. The government has banned the capture and trade of all 1,200 species of indigenous birds in India. Despite the law, birds, including munias, mynas, parrots, owls, hawks, peacocks, parakeets and other species, are openly sold in markets.
