David HoBottom trawling is horribly destructive to coastal ocean ecosystems, and deep-sea mining will do the same to the open ocean. #OceanFilm
Timothy Schwinghamer (he/him)@davidho my father (Peter Schwinghamer) used to study the effects of trawling on the benthic ecosystem. He had hours of video of the ocean bottom desertified by trawling. It was horrifying.
David Mayhood@schwinghamer @davidho I wondered if you were related to Peter. I was a classmate of Peter at UCalgary, late 1960s. A bright guy, went on to Dalhousie, didn’t he? Did great work on marine benthos.
