Humans are getting more and more adventurous by the day. A few non-adventurous folks would love to watch sharks in aquariums, and a few would love to watch them in their natural habitat behind a protective cage.
The daring ones dive down deep into the water, with their scuba gear, and ride on the sharks. Sharks would not bother about being scootered by the humans, as long as they get their next good meal.
Though this adventure is catching on, it’s not all OK and safe to try out this sport, and is illegal too.
