Paul Ehrlich and The Bet
The real lesson everyone misses about Paul Ehrlich and his famous wager.
Paul Ehrlich died last weekend at the age of 93. Among scientists, he was celebrated for his work on population biology, integrating economics and ecology, and for his creation (with Peter Raven) of the field of co-evolution, the study of how species influence each other’s evolution. To the public, he was much better known as …

Proposed CEQA ballot initiative might create unexpected, large gaps in existing environmental protections in California.
This is the ninth in a series of blog posts on the California Chamber of Commerce’s proposed ballot initiative amending the California Environmental Quality Act (CEQA). The first blog post is here. The second blog post is here. The third blog post is here. The fourth blog post is here. The fifth blog post is …

Species may be vulnerable not just to changes in climate or habitat, but also to changes in politics
Conservation biologists have long studied many different kinds of risks to endangered species: Risks from climate change, or from habitat fragmentation, or from having small populations for extended periods of time. But there is another key component of risk that has not been analyzed yet, but may matter as much or more to many endangered …

CONTINUE READINGFake species?
Looking at the data on ESA listed species to see if enviro groups strategically identify species to block development.
This tweet, arguing that it’s “an open secret at this point that environmental activists try to invent fake ‘endangered’ species to block infrastructure projects they don’t like” got a lot of traction. But is it correct? It turns out that a paper I did (with Berry Brosi) about 15 years ago provides some insights into …

CONTINUE READINGThe Trump Administration is Squandering Our Natural Heritage
Proposed Endangered Species Act regulations are designed to stifle protections and provide developers even more power.
The world’s ecosystems have been subject to an increasingly dangerous cocktail of stressors from land and ocean over-development, invasive species, and pollution. But rather than stem the tide of these harms, the Trump administration has resurrected several regulatory changes to the Endangered Species Act designed to stifle species’ protections and provide land developers even more power to …

CONTINUE READINGPing-pong government and the ESA
Recent proposed revisions for the ESA just reset the clock to 2020.
The Trump Administration in November proposed revisions to the regulations implementing the Endangered Species Act (ESA). Normally, I would try to do a thoughtful review of the changes and what I think their implications are. But that is really not necessary this time, since what the Administration is proposing is to undo Biden Administration changes …

CONTINUE READINGSome Good News To Close Out This Year
Despite the Trump Administration’s attempts to bring the world into the dark ages, lots of light is blazing
I’m a pretty pessimistic guy. Finding the dark cloud behind the silver lining is something of a specialty for me. But maybe at the end of an atrocious year for environmental law and policy in the United States, we should look for the good news, and thanks to the good people at Canary Media, there …

CONTINUE READINGYes, It’s That Time of Year Again
If you read Legal Planet, you know why the work we do matters.
Like everyone else, I’m sure you find fundraising appeals annoying. That’s why we only do them twice a year. But there couldn’t be a more important time for the work we do, given the urgency of the climate crisis and the ongoing policy disaster in D.C.
Trump’s second term has proved to be even more ruinous than expected for the environment, with a dedicated effort to slash pollution regulation, suppress clean energy, and glorify fossil fuels. That makes the environmental work we do at Berkeley and UCLA more urgent than ever.

It’s been a horrible year for federal environmental law, but there are hopeful developments elsewhere.
This is, if not the winter of our discontent, at least the late autumn. In terms of federal environmental policy, 2025 has been a disaster. Trump’s previous term in office pales by comparison. But all is not gloomy. Outside of D.C., there have been encouraging developments within the U.S. and globally.
Here are ten of those positive developments.
Fixing Fix Our Forests
The emergency provisions of Fix Our Forests are a key weakness in the bill
The permitting reform bill that has made the most progress through Congress is the Fix Our Forests Act, which I’ve written about here, here, and here. And as I’ve written before, fixing fire management on federal lands should be a top priority for any reforms. I’m not sure that the model of Fix Our Forests …
