This resource is an article and a 5-minute audio news report discussing the recent catastrophic manatee die-off in the Indian River Lagoon in Florida. Climate change and other human-caused impacts, such as runoff, have severely impacted the seagrass that manatees eat and thus have impacted manatee populations. This recent die-off seems to be a tipping point indicating a severe degradation of lagoon ecosystem health. This resource is recommended for teaching.
