Fun With Animal Materials is a good activity — too bad it’s so inappropriately named!
In an engaging way helps players see how many animals have become endangered because of the way societies (and poachers) have used them for their horns, skin or fur. It’s done appropriately for children, and it’s accessible to English Language Learners, and and it’s educational for everyone. I just wouldn’t have used the word “fun” to describe it.
