　　In 1973, the Indian government initiated a tiger protection campaign called ‘Project Tiger’ which was designed to help protect the diminishing tiger population. The tiger population was declining due to habitat loss, poaching and other human-related factors. During the campaign, twenty-five tiger reserves were established where human development and inhabitation was forbidden. On these reserves, the breeding of tigers has been facilitated, and mature tigers have been transported to other regions with the goal of increasing their worldwide population. At the same time, the campaign has organized the Tiger Protection Force to catch poachers and relocate villagers in the rural areas so that they are no longer living within natural habitats. As a result of these efforts, the population of Bengal tigers in India has increased from about 1,200 in 1973 to an impressive 3500 in 2007. Due to this fact, they are no longer on the brink of extinction.
