Everyone agrees that unless the world’s tiger population is protected, tigers will eventually become extinct. If it were not for the efforts made by international campaigns over past decades, the extinction would already have become a fact. Tigers can coexist with human beings provided local people are involved in conservation. However, even if tiger habitats are redeveloped there is no guarantee of success. Government agencies must be involved, and there must be adequate finance: otherwise conservation projects are neglected. An organized programme with safeguards must be introduced. If not the illegal hunters quickly move back in. Supposing there were no tigers left in the world: how would we all feel? According to some environmentalists, that day may be coming sooner rather than later.
