Rising levels of carbon dioxide don't just cause global warming, writes Jason Hall-Spencer. Another consequence is acidifying oceans - which promises to disrupt marine ecology around the world, killing off oysters and corals, while boosting 'nuisance species' like stinging jellyfish.
The UK's coastal waters are producing little but tiddlers and scallops, writes Jason Hall-Spencer - and to blame is the endless gouging of the seabed by trawlers and dredgers - even in 'marine reserves'. We must allow our marine ecosystems to rebuild!
