Crabby’s Reef

The game has a familiar arcade style. Move Crabby around the reef collecting food pellets and dodging predators.

Increasing levels of carbon dioxide in the atmosphere are increasing the rate it is absorbed by the world’s oceans. When it interacts with sea water it produces carbonic acid and over time this lowers the pH of the oceans and makes them more acidic.

Marine animals are adapted for an ocean that has a pH at current levels, around 8.1. As it lowers this inhibits their ability to smell food and predators, amongst other effects, endangering their lives.

The majority of people are unaware of ocean acidification and its links to climate change. Our game demonstrates how increasing ocean acidity makes life harder for marine animals and raises awareness of the issue.
