This story was originally published by High Country News. It appears here as part of the Climate Desk collaboration. It’s a cloudy gray day in Cully, a neighborhood in northeastern Portland, and the air is thick with the smell of burnt tires. The culprit? An asphalt manufacturing plant, where black rubble is piled into one long heaping mound, waiting to be hauled off to areas across the city to fill in old potholes and pave new streets. Cully is located in one of the city’s most culturally diverse pockets, but the predominantly low-income neighborhood is regularly subject to industrial pollution.
