Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

Engaging People, Engaging Lakes: How The Public Can Help Aquatic Systems
Jo Latimore’s interest in aquatic ecology dates back to her childhood, spending time at her parents’ North Michigan cabin, exploring the water nearby. Today she is a senior academic specialist, aquatic ecologist, and outreach specialist at Michigan State University in the Department of Fisheries and Wildlife , in her thirteenth year in the position. Latimore’s primary interests include lake appreciation and engagement. “Most people appreciate our lakes. They like to look at, fish on, and boat on them. However, they don’t necessarily appreciate our lakes as an ecosystem,” Latimore said. “It’s the health of the lakes that lets us use them recreationally.

Aquatic Systems Connectivity: Finding Relationships Between Waters
An early aquatic science pioneer, Luna Leopold, said that “The health of our waters is the principal measure of how we live on the land.” Determining how the land impacts water quality, however, is complex. There must be an understanding of the flow of materials, organisms, and energy within our waters and how they are connected, or even whether they are connected. Enter the emerging field of aquatic systems connectivity.
