How can you prevent the tigers from becoming extinct?

Tigers are threatened by deforestation and poaching. To protect them from deforestation, it is important to avoid purchasing wood products, especially rainforest woods, and paper products that do not have the FSC (Forest Stewardship Council) symbol on them (because if they don't have the symbol, the odds are that the wood was NOT sustainably harvested, and contributed to deforestation). Also, don't buy products that contain palm oil, because palm oil plantations are one of the major causes of deforestation in Southeast Asia, where many tigers live. To protect them from poaching, donate, if you can, to an organization such as the World Wildlife Fund, that actively searches for poachers in tigers' native habitats.
