These yummy fishcakes will be a hit with any guests.

Have you watched Seaspiracy on Netflix? I watched it recently and am still shocked by it. I reckon I knew a little about the crisis in the world’s oceans but I had no idea just how shockingly serious the picture is nor did I fully realise that the future of mankind depends even more on the state of the seas and fish stocks than on what happens on land.

I now understand that the ocean absorbs more than 90% of the heat that enters the atmosphere; it provides more than half of the oxygen we breathe; it supplies more than 3 billion people with 20% of their daily protein needs; it enables global trade and transport, and provides healthy food and a livelihood to millions, if not billions of people. Without the ocean, humans could not exist on Earth.
