VOICED: Mexico City struggles with waste disposal

The video discusses the closure of a major dump in Mexico City, which was part of a plan to reduce greenhouse gas emissions.

The video highlights the ongoing challenges in trash disposal and the uncertain future for those who depend on it for their livelihood.
