  • Part of nature

    I cannot describe the disgust I feel when people try to put humans outside of nature. Do you not realize the things you are saying are tantamount to the religious trying to put humans above and outside of the natural world? Everything humans do is just as natural as all the things every other living creature does.

    In awe of a podcast that brings to life both the intensely human UN COP climate meetings process (couple seasons back) and the beyond-human soundscape (current season). Unforgettable, indispensable.

Talking Points

Recent interactions between the hosts and their guests.

The Corridor | 5 | You’ve Got To Fight
Q: What are you going to do about the high cancer rates in your hometown?
Clinton responds that medical research and environmental cleanup investments are needed, and that action should focus on protecting communities and expanding health investigations.
The Corridor | 4 | What Can Be Measured Can Be Changed
Q: Why is monitoring data not enough to prove risk?
Because monitoring often covers only a subset of pollutants, stations are unevenly placed, data is reported at parish level rather than neighborhood level, and latency and historical exposure are not captured, making it hard to prove causation for cancer or other diseases.
The Corridor | 4 | What Can Be Measured Can Be Changed
Q: What is the link between pollution and cancer in the corridor?
There is a known association between air pollutants from plants (like benzene, chloroprene, and ethylene oxide) and higher cancer risk, with data showing higher pollution exposure in nearby Black communities and studies linking those exposures to increased cancer incidence, though establishing a direct line is complex due to latency and confounding factors.
Threshold Conversations | Coyotes in the City with Christopher Schell
Q: So I have to start by asking you to tell me the story of the Quiznos Coyote.
The Quiznos Coyote story is used to illustrate how wildlife can enter human spaces and how people react, showing that such events are not as rare as they seem and highlighting the ecological reality of coyotes in urban environments.
Threshold Conversations | Walking Like a Curlew with Matthew Trevelyan
Q: What are the main threats facing curlews today, and how do farming practices contribute?
Threats vary by region but include habitat loss, ground-nesting vulnerability during grass harvests, predation by foxes and crows, and climate-related changes; intensive farming and multiple summer cuts shorten nesting windows and increase chick mortality, driving declines.
