What should i do with my turtles?

I'm 15. I have two red-eared slider. and they're getting bigger and the tank is too small for them. I don't even have a garden. My parents are giving them away to the crocodile farm, they said i should set them free. but putting them in the croc farm aint really free after all. I was wondering if i could put them in a pond in a jungle. will they be safe in the wild? Or beg my parents to let me keep them? =/
