The People Who Refuse to Let California's Coast Go Quietly

There is a particular kind of person who keeps showing up to the meeting nobody else attends. Who reads the 200 page environmental impact statement. Who sits through the public comment period in a fluorescent lit government room in Sacramento, waiting for their three minutes at the microphone. Who, on a Tuesday morning, takes a boat full of kids out past the Golden Gate to show them what is actually out there.

David McGuire is that kind of person, and the organization he founded, Shark Stewards, is made up of those people.

You have probably never heard of them. Their office is in Sausalito. Their budget would not cover a single direct mail campaign at a large national environmental group. And yet, over two decades, this tiny outfit has done things that much bigger organizations have not. They wrote the playbook for banning the shark fin trade in the United States. They defended a California law all the way to the Supreme Court and won. And right now, they are one of the loudest voices standing between the California coast and a wave of new oil drilling.

The thing they are fighting

The federal government has proposed opening huge stretches of California, both ocean and land, to new oil and gas extraction. Not in some distant theoretical future. Now.

These are not empty waters and barren hills. The sanctuaries off our coast are some of the richest feeding grounds on the planet, where blue whales, humpbacks, gray whales, and white sharks come to eat. They hold up entire local economies built on fishing, tourism, and the simple fact that people want to live somewhere the ocean is still alive.

Shark Stewards has met both proposals the way they meet everything: by showing up. They organized a march on the State Capitol. They wrote comment letters and put them in the hands of thousands of ordinary people who would never otherwise know how to talk to a federal agency. They brought a thousand people to the water's edge in Berkeley to say, plainly, that this coast is not for sale.

A small nonprofit cannot stop a federal agency by itself. What it can do is make sure that when the decision is made, no one can claim they did not know what was at stake.

Why this is happening now

It would be easy to assume the laws that protect our oceans are permanent. They are not.

This is the ground Shark Stewards is standing on. It is not lost on them how much is slipping at once. But they have been here before, and they know that pressure works in both directions. In 2025, a federal court struck down an earlier attempt to weaken the Endangered Species Act, restoring protections it had held for fifty years. Shark Stewards was part of the coalition that fought it.

The whales in the Bay

Some of the most affecting work they do is the closest to home.

If you have driven across a Bay Area bridge in the last few years, you may have shared that view with a whale. Gray whales have been coming into San Francisco Bay more often, and staying longer, because the warming ocean has left them hungry. They come looking for food. Too many of them do not leave.

McGuire studied these animals as a young man, in the lagoons of Baja where they are born.

His organization has endorsed the Save Willy Act, introduced in 2026, which would create a real time alert system to warn ships when whales are in the water. They are pushing to make the slow down speed limits mandatory, not optional. It is a small, practical fix to a heartbreaking problem, which is exactly the kind of fight they tend to win.

Why we are telling you this

At Essential Oxygen, we make products with food grade hydrogen peroxide, which breaks down into nothing but water and oxygen. We think a lot about where things go after they leave our hands, and the honest answer is that almost everything ends up in the ocean eventually. Every drain leads there.

So we pay attention to the people protecting it. Not the ones with the biggest budgets, but the ones doing the patient, unglamorous, deeply local work that actually changes outcomes. The ones who show up.

There is a story we tell ourselves when the losses feel too big, which is that small efforts do not matter. Shark Stewards is the cleanest rebuttal we know. A handful of people, one boat, and a refusal to let the coast go quietly have added up to laws on the books, a Supreme Court win, and a coastline that still has its defenders.

That is not nothing. That is how it gets done.
