Deep sea mining in the U.S. is entering a new chapter after a recent executive order signed by former President Donald Trump authorized exploration and extraction not only in U.S. Exclusive Economic Zones but potentially in international waters. This move marks a dramatic shift in ocean policy and raises serious questions about compliance with the United Nations Convention on the Law of the Sea (U...

Coral bleaching is not just a temporary event—it's a climate emergency that can unfold over years. In this episode of How to Protect the Ocean , host Andrew Lewin dives deep into the devastating history of global coral bleaching events, revealing how the fourth and current one (2023–2025) is affecting over 80% of coral reefs worldwide. From the Great Barrier Reef to the Caribbean, bleaching is now...

Octopus intelligence is nothing short of extraordinary—and in this episode, we dive deep with award-winning author Mark Leiren-Young to explore the surprising minds, behaviors, and conservation challenges of one of the ocean's most elusive animals.

Energy policy shifts in the U.S. are sparking concern as the government rolls back environmental regulations to fast-track oil and gas drilling. In this episode, we examine how these rollbacks could jeopardize ecosystems, especially marine environments, and undermine efforts to transition to clean energy sources. Environmental protections have long served as safeguards for biodiversity and climate...

Equity, Diversity, and Inclusion (EDI) have become integral components of Canadian science funding. In this episode, we explore Pierre Poilievre's plan to strip funding from research programs that incorporate so-called "woke" policies like EDI. We examine how EDI policies are currently embedded in major grants from NSERC, SSHRC, CIHR, and more, and discuss what could be at stake for Canada's resea...

Fisheries : In this episode, we see the surprising news that the U.S. government is opening up parts of its marine protected areas (MPAs) to commercial fishing.
