Scientists say one of the greatest environmental and economic disasters in the nation’s history — the rapid land loss occurring in Southeast Louisiana — is rushing toward a catastrophic conclusion over the next 50 years. On Thursday, The Lens and ProPublica launched “Losing Ground,” an interactive project that lets readers explore the issues, including why it’s happening and what we’ll all lose if we do nothing to stop it.

On Friday, Aug. 29 at noon CT (1 p.m. ET), The Lens and ProPublica will host a live chat to discuss the project. Reporters Bob Marshall from The Lens and Al Shaw from ProPublica will be here to talk about how they reported the story and created the interactive maps, what spurred them to do it now, and to answer your questions.
