Death Zone: Cleaning Everest [AKA Everest Death Zone) (2018, dir. Marina Martins)

A team of Nepalese clear Everest of detritus left by climbers, while also retrieving bodies. Slightly clumsy, but well-meaning and with a strong central message, this Patrick Stewart-narrated documentary makes clear environmental points as well as commenting on wasteful adventure tourism.

Here’s the trailer.
