As another year comes to a close, I am reflecting on the incredible progress Ocean Conservancy has made in 2023 towards a healthy, resilient ocean future. For better or worse, this is the nature of ocean conservation work—sometimes we hit roadblocks, but it’s a reminder of why this work is so critically important.
