F34nor writes to mention a CBS news article about the depopulation of ocean species. According to a study by a scientist in Halifax, Nova Scotia and assisted by research from all around the world, the world's oceans will be emptied of large lifeforms by 2048. From the article: "Already, 29% of edible fish and seafood species have declined by 90% — a drop that means the collapse of these fisheries. But the issue isn't just having seafood on our plates. Ocean species filter toxins from the water. They protect shorelines. And they reduce the risks of algae blooms such as the red tide. 'A large and increasing proportion of our population lives close to the coast; thus the loss of services such as flood control and waste detoxification can have disastrous consequences,' Worm and colleagues say."
