A mother monkey is teaching her baby monkey how to eat human junk food (Java, Indonesia)
Tentatively identified as Macaca fascicularis.
Those are wild macaque monkeys, but locals often feed them junk food, and wild monkeys also manage to snatch food from people's bags.
Monkeys found out that the "good" stuff is inside the plastic bag, and they throw away the wrapping, causing even more plastic trash in the landscape.
Please, people, feed monkeys fruits, not human junkfood!
