My book “Racing To Extinction” analyzes the imminent disappearance of humanity through the lens of my 30+ years as an ecologist with federal environmental agencies in the U.S.

We call it wilderness, but every branch, every tidepool, every bear carries the memory of what humans choose to forget.

Long before agriculture, humans reshaped life on Earth — carelessly squandering millions of years of evolution.

Protecting a species without protecting its ecosystem is like saving a single lung and calling the patient cured. Stay tuned. My upcoming essay on the Endangered Species Act explores how policy too often mistakes paperwork for protection.

By romanticizing the past and rationalizing the present, we hide from the enormity of what we’ve done…..and are still doing to Earth’s living systems.

We didn’t just fill the sky with carbon — we dismantled Earth’s ability to absorb it. Forests, wetlands, soils, oceans — the lungs, heart, skin, and blood of a living planet.

Ecology is as much art as science. It asks us to interpret a world too complex to fully measure, too interconnected to isolate, and too ancient to replicate. The deeper we go, the clearer it becomes: understanding life means listening, not just modeling.

Extinctions unfold not through one fatal blow, but through the slow convergence of many.

The things humanity clings to — corporations, money, nations, religions — are not anchors. They’re myths. And when the storm comes, they will turn to dust and blow away.

In a world of increasing risk and uncertainty, you can only attempt to guide your life in the right direction. There will be times it gallops off another way. Do what you can. Enjoy what you can.

Some of the most dramatic human-induced changes to the nature of life on Earth occurred before the dawn of agriculture — damage that remains etched into ecosystems planet-wide.

I’ll be heading offline for a while…..back to the wilderness, where signal fades and perspective returns. Posts will keep running while I’m gone, but I won’t be around to reply. See you when I return.

“Planet is greening” has data behind it, but without context, it misleads. It’s become a lifeline for climate deniers who mistake leafier maps for recovery. That’s the illusion of green.

When a species finally begins to recover, it becomes a problem to be managed. We want to repeat what sent their population into a tailspin to begin with only now there’s less habitat left to support their existence.

Balance is a euphemism for keeping things the way we like them. There’s no solid evidence that hunting makes bears safer for people. Most conflicts happen where people expand into bear country, not the other way around. 2/3

“Sustainable bear management” is the phrase we use when we want nature to conform to our whims and desires.
The hunt didn’t end because grizzlies were overpopulated. It ended because they were struggling to stabilize after centuries of decline.🧵

We’ve framed the story as competition between two owls, but it’s really about what happens when ecosystems meet a predator they never knew. 4/4

Their influence reaches far beyond the spotted owl. Barred owls kill smaller owls, hunt species that never evolved with them, and pack into dense home ranges that rewrite entire forest food webs. Most of it still unstudied. 3/4

Logging and fragmentation magnify their impact.
Barred owls thrive where old-growth structure is lost, pushing Northern Spotted Owls toward extinction.

Barred owls are an invasive species in western North America. Their westward spread was fueled by fire suppression, tree planting, and settlement, not by “natural expansion.” (Livezey 2009)

National Parks are a mirror of democracy — owned by the people, protected for all. Which is why, in an age of privatization and neglect, they’ve never been more imperiled.

@grok insists technology can outgrow scarcity and that “managed forests” and “tech-engineered biospheres” can replace wild systems, treating Earth as a prototype to be upgraded.
Simplification: life reduced to what can be managed. Collapse becomes a feature.

Conservation isn’t just about numbers—it’s about connection. Wildlife corridors keep tigers, lions, cheetahs & leopards roaming, breeding & surviving. Isolation turns parks into islands of extinction.
