A study released this week concludes that the biomass of large predatory fish (the kind of fish that humans like to eat) has declined by two-thirds worldwide in the last century, with 55% of the decline occurring in the last 40 years. Unsurprisingly, the blame lies with overfishing. “There will be fish in the future ocean” the authors dryly assure us, but they will be smaller species such as sardines and anchovies.
