Hearing that a dispersant is just as harmful as oil to corals is a hard pill to swallow, especially when it’s used to cleanup a whopping 200 million gallons of oil. To make matters worse, some types of coral were not able to survive in laboratory tests with the smallest amount of the dispersant Corexit 9500–.86 parts per million.

4.Fresh Insight on the Genetically-Modified Salmon Debate

Our new blog post caught users’ attention with the controversial topic of GMOs. Our expert George Leonard weighed in on news about well-known anti-GMO activist Mark Lynas’ switch in sentiment. George argues that we should continue to be skeptical about genetically modified salmon until more research into the effects of it are better known, and illuminates Ocean Conservancy’s opinion that the concern over GMOs is largely due to the unknown results that would occur if these fish were to accidentally be released into the wild. This hot-button issue lit up our Twitter feed, and will likely continue to do so as the deadline for public comments on the issue are due to the FDA by February 25.
