A curious shark

The Year of the Shark 2019 Ends

What we see is that sharks are being targeted by international factory fleets around the world who trail millions upon millions of baited hooks through their realm, trawl the sea floors for rays, skates and other bottom dwellers to 4,000 metres, and slaughter them by the millions. Sharks are the only profitable prey remaining, now that ninety percent of the original (fish) fisheries are fished out.

It was a beautiful day in Indonesia’s Banda Sea. Richard rolled back into the warm waters and swam over to join his wife, Florence.

There are no dive centres in your town.

Anna’s story: “I was on my eighth or ninth dive, about five minutes in and at a depth of around 13 metres when I realized that my air was not coming out smoothly. I couldn’t think why this should be. I had checked my pressure gauge on descent and it had shown 190 bar. I switched to my octopus, but there was no difference. Soon the air became very thin.
