Experts believe that the reason for the sharp decline in tiger populations is simple: illegal hunting of wild animals has not been completely banned, and many countries in East Asia are still rampantly trading in animal skins. Experts point out that the new population growth trends and economic changes in Asia The survival of tigers have had a very significant impact. The wealthy middle class in Asia can afford the expensive "Tiger Feast"-making dinner from various parts of the tiger's body to show off wealth. This has also fully stimulated the illegal trade of wild tigers, which directly led The number of Asian tigers has plummeted. From this we can infer:. ['Reduce the number of tigers that will be killed.', 'Stop the animal fur trade, the number of tigers will not fall.', 'Economic changes have a significant impact on the survival of some animals.', 'If the middle class changes unhealthy consumption attitudes, the number of tigers will not decline.']
