Try to imagine what the world will look like if human-caused carbon-dioxide emissions aren’t curbed. If your imagination and scientific knowledge can’t take you there, virtual reality can.

The Stanford Ocean Acidification Experience, a free science education tool (download here), can take you to the bottom of the sea, then fast-forward to the end of the century, when many coral reefs are predicted to corrode in waters made acidic by the absorption of carbon dioxide from the atmosphere.

“You’re not watching something, you’re doing it,” said communication Professor Jeremy Bailenson, whose Virtual Human Interaction Lab developed the software. “You learn by doing. These are magic, teachable moments.”

Although a dire threat to coral and other marine systems that provide food and employment for hundreds of millions of people, ocean acidification is not a well-known phenomenon.

Coral reefs are particularly vulnerable to acidification’s effects on the building of calcium carbonate skeletons and shells.

An immersive experience

The virtual reality simulation allows users to stand in heavy traffic and follow carbon dioxide molecules from car tailpipes to the sea, where they are absorbed. Deep below the waves, you can move amid coral as it loses its vitality and observe the effects of increasingly acidic water on marine life.

A narrator explains the processes unfolding before you and encourages you to interact by doing activities such as a species count. Hand controls with haptic feedback make the experience more immersive.
