Interview with Callum Roberts

Interview with Callum Roberts, author of
The Ocean of Life: The Fate of Man and Sea

Ocean of Life, by Callum Roberts

“Overfishing is the world’s biggest solvable environmental problem. We know what to do and if we were to act decisively, it would take only 15 years to fix most of what has gone wrong.”

—Callum Roberts

Roberts, “The Rachel Carson of the fish world” (The New York Times) has written his magnum opus: a love letter to the sea, from the first spark of life to today. The Ocean Of Life tells the story of humankind’s long relationship with the sea and its creatures, and shows how the fate of our oceans will ultimately determine our own future. Continuing on our current course of excessive fishing, using the sea as a dump, and planetary transformation is not possible if we are to survive and thrive. Change is possible, and The Ocean Of Life is infused with optimism, hope and practical solutions for the future.

Juliet Eilperin, Washington Post Reporter and Author, on Journalism, Seafood and Sharks


Juliet Eilperin, author and national environmental reporter for the Washington Post, sat down with SeaWeb and discussed her experiences and insights on the importance of journalism in moving environmental conservation forward and how she shifts between her role as a reporter and author. Eilperin continues with a glimpse into her love affair with the ocean's most misunderstood animal, sharks, the subject of her book Demon Fish. The ever-evolving conversation about sustainability pertaining to the ocean is addressed and specifically how it is affecting global fisheries. Special thanks to Juliet for her time and insights into these critical issues.

Parting Shot - 33 Years Later in Disco Bay...

The above photo on the left was taken in 1978, and on the right, in 2011. Both were snapped in the same exact location in a reef off of Discovery Bay Research Lab on the north coast of Jamaica. Upon careful inspection, you can see that the pin nearest to the camera in the older photograph is still present in the recent image, 33 years later. What happened to this once-beautiful reef?

There are several possible explanations for coral degradation— disease, bleaching induced by increased ocean temperatures, natural disasters, removal for the home aquarium trade, and even from people stepping on the sensitive animal while snorkeling. The truth lies in a combination of these factors.

In Disco Bay, the overgrowth of macroalgae was a top-down problem that started with the loss of top predatory fish including sharks, groupers and jacks, according to researchers Richard B. Aronson and William F. Precht in an article published in Limnology and Oceanography.

Fisheries exhausted the large fish stocks and then moved on to target smaller fish, including vital herbivorous grazers.

The mass death of the sea urchin Diadema antillarum in the region in 1983 was another major factor in stopping Disco Bay’s growth. Sea urchins prey on algae and keep algae growth in check.

Disco Bay has not yet recovered from these traumas. Coral is sometimes envisioned as rock because it has a calcium carbonate skeleton, but coral is an animal and very sensitive to the pH and nutrient levels of the water in which it lives.

Threats facing coral reefs, new scientific findings, sustainable management opportunities and other coral issues will be discussed at the 2012 International Coral Reef Symposium in Cairns, Australia July 9 - 13. If you'll be attending, please share your photos with us after the Symposium! Follow the conversation on Twitter: @ICRS2012 and #ICRS2012.
