Built on Climate Change Science


Lost City of Mer is built on science in order to educate and activate the general public about the threat climate change poses to the health of our planet. Coral reefs support a quarter of all marine species and are one of the most important ecosystems

on earth. It is estimated that by 2050 most of them will be gone

if there is no large scale action.  

 In Lost City of Mer learn about ocean temperature rise and acidification, the threat posed by pollution, over-fishing and solutions.

Science Bubbles


Your Mer scientist mom left clues in bubble messages for you about why the Mer civilization collapsed, and what actions to take to bring it back to life.

Coming Soon in Chapter Two

For example, this bubble explains the carbon cycle and what you can do about it in the human realm when you are on land. 


Coral Planting has shown to be a viable method for restoring some dying reefs.

Design your own coral garden, and watch as it revives the ecosystem with exotic sea creatures.

Polluted water pours into The Secret Coral Garden, the only place in Mer that is still alive. Can you stop the pollution and save the reef?

A science bubble reveals that industrial agriculture is pouring reactive nitrogen and phosphorous into the oceans through rivers, creating “ocean dead zones”.  We have the ability to rectify coastal pollution by changing farming practices.

Carbon Dioxide Meter


The CO  and water temperature meter responds to the player's real world actions to lower their carbon

footprint as a form of gameplay and informs players about the impact of carbon on the ocean.

Functionality Coming Soon in Chapter Two
