If it was nighttime the risks would be: getting sick from being cold at night, and the possibility of drowning due to the lack do sight at night. But if it wasn’t the risks would be: Lack of supervision because most likely youre parents wouldn’t be there and chance of getting diseases or sickness from the animals. Another risk would be getting bitten by an animal. A benefit would be having fun and swimming if you don’t have an pool.
