Tourist snacks are making the Rock of Gibraltar's monkeys sick, and their solution will make you laugh

Monkeys in Gibraltar are changing their behaviour after consuming human snacks provided by tourists. Foods like chocolate, crisps, and ice cream are causing digestive issues, leading scientists to observe an unusual response. The behaviour is more common in tourist-heavy areas and increases during peak seasons. Scientists believe it is socially learned within groups. The study highlights how human food habits are directly influencing wildlife behaviour and health in unexpected ways across the Rock of Gibraltar ecosystem.
