A man who has profited from the abundance of the oceans through his fishing business, now wants to give back to the waters that gave him so much. Kjell Inge Røkke, a Norwegian billionaire, is investing “the lion’s share” of his $2.7 billion fortune to build the Research Expedition Vessel (REV) - a 600-foot ship that will travel the oceans sucking up plastic waste. It is capable of accumulating and recycling up to five tons of plastic per day, and it will also double as a mobile laboratory for scientists to monitor and observe the oceans’ ecosystems.
