Despite covering less than 1% of the ocean floor, coral reefs are estimated to be home to about 25% of all marine species. Unfortunately, these vibrant underwater cities are dying. Climate change and its effect of rising sea temperatures is devastating the colorful algae that give coral reefs their brilliant hues, resulting in coral bleaching. Furthermore, other threats like pollution—in its various insidious forms—and overfishing are disrupting the delicate balance of reef ecosystems. And so, scientists from various fields, along with the researchers studying the ecological complexity and significance of the reefs, are collaborating to address the myriad challenges facing these ecosystems. Your assignment is to take command of a scientific vessel and embark on a journey of reef conservation. Hire the best crew, clean the ocean, and restore the reefs to their former glory.
