The International Tiger Day is celebrated on July 29 to spread awareness about the need to protect tigers which are an endangered species. Tigers have lost 90% of their natural habitat and their world population is less than 4,000. The day was marked for the first time in 2010 at the 'Saint Petersburg Tiger Summit' in Russia which aimed to double the tiger population by 2022.
