Profiting from animals or even abusing them to satisfy tourists' curiosity and achieve a profit is all too common, and related news reports can often be seen: a certain zoo anesthetizes a tiger so that visitors can pay to take photos holding it... a certain attraction pulls out the fangs from venomous snakes for tourists to play with... a certain site deliberately skimps on animal food, leaving them weak and listless to elicit the sympathy of visitors...
Just a few days ago, news even broke that a temple abroad specializing in raising tigers was secretly selling tiger cubs for money.
As long as there is profit to be made, some will engage in any trade, let alone when the victims are those "who can't speak for themselves," and whether domestically or internationally, there are many who make a dishonest living off animals.
