Our marine scientists see trash, primarily plastic, floating in the ocean every time they go offshore. Studies from our university partners at NCSU analyzed the stomach contents of 50 fish (mahi, wahoo, and blue marlin) caught in a major fishing tournament. They were looking for microplastics and found them in every single stomach sampled. Our partners at VCU have been deploying tags on the endangered Atlantic sturgeon in the James River. They have tagged Atlantic sturgeon after freeing them from plastic debris. We're also seeing plastic on the seafloor in the deep sea.You are making a dfference!Through 10 years of this cleanup:<ul><li>4,546 volunteers</li><li>donated 10,618 hours</li><li>removed 31 tons of trash</li><li>cleaned 150+ miles of local streams, shorelines and trails</li></ul>Through your support of The Nature Conservancy and Fairfax County Park Authority, we can continue to preserve and protect the places you care for most.For information about Fairfax County Park access &amp; accomodations visit: <a href="https://www.fairfaxcounty.gov/parks/accessible" title="https://www.fairfaxcounty.gov/parks/accessible" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">www.fairfaxcounty.gov/parks/accessible</a>.
