So in order to make much money, more and more people are massively hunting down the endangered animal such as sharks for shark fin soup, elephants for ivories, rhinos for horns and so on.
First of all, there should be some propaganda explaining the consequences such behavior and correcting people’s wrong opinions of the products. Besides, the government should set up laws to restrict this trade and industry and anyone who breaks it will be severely punished. Last but not least, more wildlife reserves should be set up to prevent the hunters from killing the animals illegally.
All in all, human beings should raise their awareness of this problem for the earth belongs to ourselves, human can no longer exist if animals die out.
