Trawlers are bad, they overfish & because of this, there is less & less fish in the ocean, the other fishermen who depend on the sea for a living, who aren’t causing this huge problem of overfishing, & are wise enough not to overfish, so there will still be enough fish left for the next generation are struggling to make an income. It’s all Maggie Thatcher’s fault cause in 1984 she changed the law to allow trawlers to go pretty much anywhere.
That’s capitalism for you, small groups of greedy people grab as much resources as they can & get rich, but leave nothing but an environmental mess & poverty for the rest.
Industry wasn’t really progress, it was the beginning of the end for humanity & a myriad other organisms.
Capitalism & industry has caused so much environmental & social harm.
