Inside the landfill of fast-fashion: "These clothes don't even come from here"

This holiday shopping season, environmental groups are asking shoppers to reconsider buying cheaper fast-fashion items that may only get a few uses. These items often end up discarded quickly, harming the environment. 

In Chile, a massive landfill of used clothing from around the world keeps growing, causing damage to the environment and the communities that live there. 

The mountain can be found just 30 minutes away from Iquique, a port city known for its beaches and trade. It's an illegal landfill, and one of the biggest in the area. By one estimate, there are at least 30,000 tons of waste in the pile.
