Proposed Marine Phosphate Mine at Gray Whale Sanctuary

the American company Odyssey Marine Explorations intends to start the Don Diego phosphate mine. The proposed mine would include five work sites in an area of more than 225,000 acres. Each site would be exploited for 10 years, resulting in a 50-year-long project. The goal is to extract 350 million tons of phosphate sand from the marine floor—a quantity that would fill Mexico City’s Aztec Stadium 264 times.
