I’ve experienced the other end of this interaction; I was once making polite conversation with an NYC hairdresser about smoke from Canada wildfires and she told me they had been started on purpose as a way to get rid of trees.

Earlier this week I spoke with ‪@thewildlifesociety.bsky.social‬ about pending #NEPA reforms. Listen for a basic primer on NEPA, people's objections, and the subsurface disagreements that run through reform efforts.

E.P.A. to Stop Considering Lives Saved When Setting Rules on Air Pollution

I love that the justification for assigning zero quantitative value to health benefits is that they're uncertain. Because there's obviously no uncertainty on the compliance-cost side of the ledger. No need to worry about "false precision" there. www.nytimes.com/2026/01/12/c...

EPA is lipsticking this pig by saying that lives saved will be considered, just not assigned economic value. But history shows that agencies frequently undervalue unmonetized effects relative to monetized ones.

In addition to being completely divorced from EPA’s mission, this move overturns decades of precedent and is clearly irrational from an economic perspective. And it’s antithetical to the admin’s alleged commitment to MAHA.

E.P.A. to Stop Considering Lives Saved When Setting Rules on Air Pollution

This is nuts. Now, when EPA does a cost-benefit analysis of a regulation, it can only consider downsides to industry, not upsides to public health. Even though the latter is the core mission of the EPA.

Opinion | Obama Supported It. The Left in Canada and Norway Does. Why Don’t Democrats?

This Yglesias piece in the NYT is horrifically bad. Almost every "fact" it cites is provably false. At best it is cocktail party banter from a pundit who knows nothing of energy. At worst, it was cut/paste from oil industry talking points. So, a rebuttal: www.nytimes.com/2025/12/18/o...

TIL that a mountain goat is not a goat.

@themountaingoats.bsky.social is also not a goat.

Specifically, we argue: (1) FWS must consider economic benefits of *including* areas in critical habitat, not just benefits of exclusion and (2) FWS should recognize that Americans are willing to pay for species conservation. Conservation not only drives tourism, etc.; it has economic value itself.

Critically, the ESA in most respects doesn't hinge on economic impacts, but the statute allows economics to influence critical habitat designation. Nonetheless, to comply with rational decision-making, that econ analysis cannot be lopsided against species conservation.

Prof Bob Fischer & I authored comments for the Ctr. for Policy and #Animal #Welfare on the proposed reg detailing how the Fish & Wildlife Service will analyze "economic impact" in critical habitat designation per the Endangered Species Act #ESA.

Curious how, if at all, his thoughts on permitting reform have changed under a presidency hostile to renewables and eager to speed fossil fuel projects. Does it reform now make sense if in the short term fossil fuel projects seem likeliest to benefit? Does the type of reform that is prudent change?

The Ocean is huge and we are stupid.

100%. Meat can also be a hard pivot for climate folks who (for good reason) deemphasize individual behavior and instead demand systemic change. But in the context of meat and dairy, consumers’ personal decisions really *can* make a big difference. Jennifer Jacquet:

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

The last passenger pigeon died 111 years ago today and not a day goes by that I don't think about how their flocks numbered in the *billions*, that their roosts covered 100+ square miles, that they collapsed trees with their nests. America is incomplete without them

Crafting a New Conservationism — California Law Review Environmental law has an animal problem. It lacks an account of whether and how animals’ interests matter. Case in point: The agencies tasked with protecting wild animals cannot stop killing them. The...

After years in development, my article Crafting a New Conservationism is out in California Law Review! It's about how U.S. agencies manage conflicts between conservation goals and individual wild animals' intrinsic value. Thanks to the many people who provided feedback and Cal.'s editors!

Granting Rights to Animals Doesn't Undermine Human Rights In proposing the Species Membership Approach, Raffael Fasel argues against the misplaced fears that granting legal rights and personhood to nonhumans would weaken human rights.

I am delighted that my book 'More Equal Than Others: Humans and the Rights of Other Animals' is featured in Psychology Today @psychologytoday.com and has been made an essential read in their Philosophy section. Many thanks to Marc Bekoff for interviewing me! www.psychologytoday.com/us/blog/anim...

Fed MT court says Fish & Wildlife Service must reconsider delisting gray wolves in light of aggressive killing by Idaho, Montana, & other western states. It’s a PSA to states not to “overdo it” once a population is delisted. Try to eradicate them and…back on the list they go!

I can’t begin to enumerate the ways the Corporation for Public Broadcasting made my life better, literally from my earliest memories until today. This is gut wrenching.
