Whales Are Sprinters: What a Blue Whale's Heart Does...

How To Protect The Ocean ·

2026/10/05

What happens to the heart of the largest animal on Earth when it charges into a swarm of krill? Dr. Ashley Blawas, a postdoctoral scholar in Jeremy Goldbogen's lab at Stanford's Hopkins Marine Station, joins Andrew to unpack new research published in PNAS that measured the heart rates of lunge-feeding blue whales and humpback whales using suction-cup ECG tags. Ashley explains the three phases of lunge feeding (accelerate, engulf, filter) and why these giants behave a lot like human sprinters. Their

How Beach Cleanup Data Helped Canada Ban Plastic

2026/10/01

You rinse the yogurt tub, check the number on the bottom, and drop it in the blue bin. In Canada, only about 9% of plastic waste actually gets recycled, and the global rate is the same. Andrew breaks down why plastic is so hard to recycle, why microplastics are so hard to study, and what the controversy over plastic-in-the-brain headlines does and doesn't tell us. Then the story moves to a beach in Stanley Park in 1994, where Vancouver Aquarium staff and volunteers started picking up trash and

How Did Humpback Whales End Up in New York Harbour?

How To Protect The Ocean ·

2026/09/29

This summer, people are boarding whale watching boats and seeing humpbacks feeding in sight of the Manhattan skyline. Fifty years ago, that same water was an open sewer, and every toilet on Manhattan's West Side flushed straight into the Hudson River, untreated. Andrew tells the story of how the whales got here, and why it took most of a century. He starts with the cause: sewers built to empty into the rivers, roughly 590 million gallons of raw sewage a day by the early 1900s, and floating screens

Plastic keeps getting made, it never goes away, and almost none of it gets recycled. Dr. Judith Weis, Professor Emerita at Rutgers University Newark and Andrew's very first guest on this podcast more than 2,000 episodes ago, returns for her fourth appearance to talk about the second edition of her book, Marine Pollution: What Everyone Needs to Know. Judith walks through every major category of marine pollution: nutrients, metals, oil, pesticides, marine debris, pharmaceuticals, ocean acidification,

You Left a Public Comment. Now What?

How To Protect The Ocean ·

2026/09/25

All week, Andrew has asked listeners to comment on and show up for California's marine protected area review. Today he answers the question that comes after: once the meeting ends and the news coverage stops, how do you find out if anything actually changed? He works through four practical questions every ocean advocate should know how to answer. First, where to find the current rules for any of the 124 MPAs in California's network (the California Department of Fish and Wildlife's own MPA pages)

Does Your Public Comment Count? Two Ocean Wins Show How

How To Protect The Ocean ·

2026/09/25

Earlier this year, about 65,000 people submitted comments on a federal deep-sea mining proposal near the Northern Mariana Islands, most of them opposed. The area under consideration nearly doubled anyway. So why should anyone show up to a public meeting about the ocean? Andrew Lewin makes the case with two marine protected area processes that earned broad public support by design. The first is the Great Barrier Reef Marine Park's Representative Areas Program, which rezoned the entire park between

The Blob Hit California's Kelp. Protected Kelp Came...

How To Protect The Ocean ·

2026/09/23

In 2014, just two years after California finished its statewide network of marine protected areas, a marine heatwave known as The Blob settled over the Pacific coast and stayed for two years. Kelp forests collapsed up and down the state, and sea star wasting disease wiped out sea stars on a scale few scientists had seen. For a network built partly to protect kelp habitat, it was the worst possible first test. Andrew Lewin walks through what the state learned when it checked. California's first

A boat's wake looks harmless right up until you watch it happen over and over. Every wake a boat throws off chips away at a shoreline that took centuries to build, and it happens on calm days, sunny days, days with no storm anywhere near. A NOAA study at Snow's Cut, North Carolina found that roughly half of all boat wake heights on that stretch of the Atlantic Intracoastal Waterway exceeded the largest wind driven waves measured there, and boats moving at the slow, considerate seeming "plowing"

Nature's Kidneys: How Coastal Wetlands Stop Ocean...

2026/09/15

Green water. A smell that won't go away. Sometimes, dead fish washing up on shore. That's what too much nitrogen does to a coastline, and it's easy to hear stories like this and feel like the ocean is just losing. This episode is the opposite of that. Here's what most people don't know: a healthy stretch of marsh or mangrove can pull nitrogen straight out of the water before it ever becomes a problem. A single restored 100-acre wetland cut nearby ammonia by 62 percent and total nitrogen by 37

Inside Ocean Conservancy's Fight to Make Washing...

How To Protect The Ocean ·

2026/09/10

Ocean Conservancy's "Not Safe for Wash" campaign is built around a simple premise: the fix for washing machine microfiber pollution already exists, so the fight isn't about inventing new technology, it's about forcing a nearly two-decade-old idea into law. Its own May 2026 poll of 1,010 Americans found concern about microplastics up 32% since 2023, nearly 9 in 10 people concerned, and 81% in favor of requiring filters on new washing machines. The public isn't the obstacle. The real opponent is AHAM,

Can Bacteria Actually Eat Plastic?

2026/09/08

Bacteria that eat plastic sounds like the fix everyone's been waiting for, and Andrew gets sent videos about it constantly. So on this solo episode, following Monday's interview with Dr. Anja Brandon of Ocean Conservancy, he goes looking for the real state of the science. The short version: it's promising, it's roughly a decade of real research deep, and it is nowhere close to running at the scale the ocean plastic crisis actually needs. The bacterium that started this whole field, Ideonella

The 90 Percent Fix Hiding in Your Laundry Room

How To Protect The Ocean ·

2026/09/07

Every time you run a load of laundry, your washing machine sheds plastic. Not metaphorically: synthetic clothing made from polyester, nylon, and rayon releases microfibers with every wash, and depending on the study, a single load can shed anywhere from a few hundred thousand to millions of them. Most of us have never thought about it, because unlike a plastic bag on the beach, you can't see it happening. In this episode, Andrew talks with Dr. Anja Brandon, Director of Plastics Policy at Ocean

Show Me the Receipts: Why I.CARE Monitors Every Coral...

2026/09/03

Most coral restoration groups check on a sample of what they've planted, often around 20 to 30 percent, and report that sample as if it represents everything in the water. I.CARE checks on all of it. Every single coral outplant gets monitored at one week, one month, 90 days, then one, two, and three years, with no substitute and nothing left unaccounted for. That rule was built in by co-founders Mike Goldberg and Dr. Kylie Smith before I.CARE ever planted its first coral, and Mike frames it as a

Mike Goldberg had over 10,000 dives and decades running a dive shop in the Florida Keys, enough time to have seen the reefs at their pristine best. Then came a coral bleaching event in 2008, and a few years later, Stony Coral Tissue Loss Disease, a still-unexplained outbreak that's killed coral tissue outright across more than 20 of Florida's roughly 45 stony coral species since 2014. At one point his wife told him directly: the reef isn't what it used to be, and it's not getting better. Get out of

2026/08/31

This year, most of the coral on the planet went through heat stress severe enough to bleach it. That's not a rounding error: 84 percent of the world's reef area, across the Pacific, Atlantic, and Indian Oceans, and NOAA had to add three brand-new alert levels to its Coral Reef Watch scale because the existing one had no category for what was happening. In this episode, Andrew breaks down exactly where global coral reefs stand right now: how the fourth global mass bleaching event on record got

Deep sea mining is no longer theoretical. In this episode, Andrew sits down with Matthew Gianni, co-founder and Political and Policy Advisor of the Deep Sea Conservation Coalition, for an in-depth look at what's actually happening on the seafloor and in the negotiating rooms deciding its fate. Matthew spent years as a commercial fisherman, including five years as a deep sea trawlerman off the Central California coast, before moving into ocean conservation with Greenpeace International and eventually

Greenwashing Exposed: Why 400+ Companies Got Caught...

2026/07/30

Businesses love to say they are sustainable. Andrew breaks down why that word is no longer enough on its own. A new EU consumer protection regulation now requires companies to prove environmental claims with evidence, and it has helped drive more than 400 greenwashing-related enforcement actions across the US, UK, EU, Canada, Australia, and India in 2026 alone. Andrew draws on his own university experience with food labeling regulation to explain how vague standards let companies technically comply

Why Sustainability Is Becoming a Business Requirement

Sustainability anxiety is real. Watching wildfires spread, sea levels rise, and ice melt while governments drag their feet on climate policy can leave anyone feeling stuck. Andrew opens today's episode by naming that frustration directly, then makes the case for where real momentum is actually coming from: business. This episode breaks down why companies are adopting sustainability practices, sometimes because they want to and sometimes because regulation and consumer pressure leave them little

The Ocean Is in Trouble, So Why Is This Report Hopeful?

The ocean is facing some of the biggest challenges in its history. Rising temperatures, marine heatwaves, coral bleaching, habitat loss, and overfishing continue to put pressure on marine ecosystems around the world. If you only follow the headlines, it can feel like ocean conservation is losing the battle. But hidden within a recent United Nations ocean report is a surprising reason for optimism. While ocean health continues to decline in many areas, the systems designed to protect the ocean are

What Happens When Whales Can't Hear Their Families?

How To Protect The Ocean ·

2026/06/17

Pilot whales rely on sound for nearly every aspect of their lives. They use vocalizations to communicate with family members, coordinate movements, find food, and navigate through their environment. But what happens when the ocean becomes so noisy that those sounds are drowned out? In this episode of How to Protect the Ocean, we explore new research suggesting that commercial shipping noise in the Strait of Gibraltar may be interfering with the ability of pilot whales to hear and communicate with
