Mangrove forest thrives around what was once Latin America's largest landfill

RIO DE JANEIRO -- It was once Latin America's largest landfill. Now, a decade after Rio de Janeiro shut it down and redoubled efforts to recover the surrounding expanse of highly polluted swamp, crabs, snails, fish and birds are once again populating the mangrove forest.
“If we didn't say this used to be a landfill, people would think it's a farm. The only thing missing is cattle,” jokes Elias Gouveia, an engineer with Comlurb, the city's garbage collection agency that is shepherding the plantation project. “This is an environmental lesson that we must learn from: nature is remarkable. If we don’t pollute nature, it heals itself.”
Gouveia, who has worked with Comlurb for 38 years, witnessed the Gramacho landfill recovery project's timid first steps in the late 1990s.
The former landfill is located right by the 148 square miles (383 square kilometers) Guanabara Bay. Between the landfill's inauguration in 1968 and 1996, some 80 million tons of garbage were dumped in the area, polluting the bay and surrounding rivers with trash and runoff.

Mangroves are of particular interest for environmental restoration for their capacity to capture and store large amounts of planet-warming carbon dioxide, Gouveia explained.
Experts say mangroves can bury even more carbon in the sediment than a tropical rainforest, making it a great tool to fight climate change.
