How do humans treat tigers?

No.1: DONT PUT DIFFERENT SPECIES INTO ANOTHER ANIMALS HABITAT! That will cause the animal a contest to find food and a home. ( Like if you release 25 female bass and 25 male bass into a river full of atlantic whitefish then the white fish will have a less chance of survving epseicaly cuz the whitefish is already prettty endangered ) No.2: TRY NOT NOT TO RELEASE TRASH! You already know, Reduse Reuse Recycal! And thats all that i know! ( For Now! ) :D
