In partnership with the International Whaling Commission, this special issue reveals the scale of challenges marine mammals face in the modern age and measures taken to protect them. Discover new multi-sector partnerships working together to mitigate the impacts of offshore activities; new tools to prevent entanglement and reduce ship strikes; and signs of progress both in the recovery of populations and sectors adopting practices to support conservation. Thank you to all the contributors and sponsors that made the first Special Edition of 2022 possible.
