India produces more than 68 million tons of trash every day. More than 17,000 tons of it is plastic. That requires immense dumps, which in cities like New Delhi, mean hills of stinking trash up to 50 meters tall. Last year, two people were killed when a large part of one of the city’s dumps crashed down onto them. (Photo by Altaf Qadri/AP Photo)
