Florida is trying to undo decades of damage to the Everglades

The state is embarking on such a massive restoration project because the aging levees and control gates surrounding Lake Okeechobee are at risk of failing during large storms and/or heavy rainfall. "The more rainwater that increases in Lake Okeechobee, the more pressure is on the lake, and that pressure can continue to build up and build up and build up and one day the levee can go," said Tammy Jackson-Moore, a Belle Glade resident who co-founded Guardians of the Glades, a nonprofit focused on community advocacy. "And we're talking about wiping out entire communities here." The rerouting has allowed for bursts of economic growth, but it does have its consequences. "The Everglades, the largest swath of subtropical wilderness in the country, is now half of its size circa 1920, and the ecosystem has deteriorated, losing wildlife and native flora," reports Motherboard. "Without a natural place to flow, stagnant water pushes toxic algae blooms into the rivers, and turns pristine ocean into sludgy waste."
