Declining fish stocks might give “crucial consequences for our species”
The world’s fish stocks are decreasing. It is estimateds that 90 % of all big fish are already gone. Dr. Michael Crawford, of Imperial College London, sys that “without plentiful DHA, we face a future of increased mental illness and intellectual deterioration. We need to face up to that urgently”. Docosahexaenoic acid (DHA) is an omega-3 fatty acid found in seafood. You can find the article in Mail Online here: Early human ancestors were ‘aquatic apes’: Living in water helped us evolve big brains and walk upright, scientists say.
Michael Crawford – one of the speakers at the Human Evolution onference in London 8-10th of May – states that Docosahexaenoic acid have been crucial for the development of our brains (as well as for other mammals making a living from the sea). According to Crawford we should eat 40 gram fish per day, 200 days a year.
However, by improving our mental health we will also completely undermine the marine stocks – and what will happen when we are another two billion people on the earth? Add overfishing to pollution, climate change and habitat destruction, and a picture of a system in crisis emerges.
