Spanning 326 acres, the Deonar dumping grounds, located in the heart of Mumbai’s lower-middle class eastern suburbs, is the largest dumping site in Asia. Around a third of the city’s trash gets dumped there each day, creating 8 million-pound trash mountains as high as a 100 feet. The landfill is literally spilling over with garbage.

A recent fire on the site, which started for reasons that aren’t yet clear, became so large that the plumes of smoke rising from it were visible from space. Via NASA’s Earth Observatory blog:

Beginning on January 27, 2016, sensors on the Terra, Aqua, and Suomi NPP satellites began to detect evidence of smoke and fire at the landfill. The fires continued to burn for four days, sometimes sending smoke into densely populated neighborhoods.

The smoke billowed for days, causing several schools to shut down in nearby neighborhoods. Rais Shaikh, a municipal official of a nearby suburb, told the Wall Street Journal, that the smoke resulted in “lots of cases of breathlessness and suffocation.” Residents from different parts of Mumbai proper also saw a thick smog around the city, as the fire caused a record-high spike in air pollution.
