Some parting thoughts from Peter Dykstra

Some good news — and a goodbye from our favorite columnist.

I’ve been giving some year-end thought to some of the undeniably bright signs amid the relentlessly gloomy news.

Here are three examples.

Fusion

Fusion? How cool is that? The Holy Grail of energy production may actually be taking its first credible steps forward. It’s been 33 years since the last big fusion announcement, and that one turned out to be a whopping, top-to-bottom hoax by a pair of grifting college professors.

This time, with the imprimatur of the U.S. Department of Energy, it seems more real but decades off. And rightfully, not without skeptics. Remember when fracking was hailed as a “bridge fuel?”

Declining denial 

Some key Republicans may be showing signs of melting on the party’s strict and monolithic climate denial. Even Kevin McCarthy, whose brazen chase of the House Speaker’s chair has seen him kowtow to the farthest right elements of the GOP, is said to be open to at least discussing carbon reduction – as long as we can drill, baby drill.

Brain breakthroughs 

There are precious few of us whose families haven’t been touched by Alzheimer’s. Recent headlines suggest breakthroughs in both understanding and treating this scourge (usual skepticism applies).

So, amidst the wildfires. bomb cyclones, cancer clusters and pandemics, the hope is out there. But you can address the problems until somebody figures out what they are.

A goodbye 

It’s been 27 years since Pete Myers co-wrote the book that brought wide attention to endocrine-disrupting chemicals. Since then, the news and science sides of his operation have helped bring to light emerging problems like bee-killing neonicotinoid pesticides, BPA, phthalates, glyphosate and many more, while training a generation of environmental scientists.

EHN’s recent journalism has focused on the spreading problems associated with that “bridge fuel” from fracking, and the enormity of the plastics problem.

This is my last column on my last weekend after eleven and a half years at Environmental Health News and The Daily Climate.

These sites were two of Pete Myers’ many brilliant ideas, and they still are. Thanks to Pete, Douglas Fischer and the whole team for allowing me to continue to be hell on wheels for the past 5 and half years. But the world is changing and I’m already a little past the standard retirement age.

I’m proud to have had a hand in hiring Brian Bienkowski, our superb editor. He in turn had a hand in hiring Kristina Marusic, who has turned out to be a star reporter.

Sorry to see me go? I strongly suggest you send a message to these folks by donating to them. If, on the other hand, you’re happy to see the end of my weekend bloviating, I strongly suggest you send a message to these folks by donating to them. The news we deliver and the science behind it is only going to get more important. And more prescient.

I’ll still be doing my public radio stuff with Steve Curwood on Living On Earth, so listen for me there. Or reach me on Twitter, such as it is these days, at @pdykstra or email peterdykstra@comcast.net.


Peter Dykstra was our weekend editor and columnist — and one of the funniest and smartest people we know.

While his views do not necessarily represent those of Environmental Health News, The Daily Climate, or publisher Environmental Health Sciences — his spirit, wit and curiosity do, so this is not the last time you'll see him on our pages.

Toxic chemicals and climate change work together to harm fertility across species

In a recent review published in NPJ Emerging Contaminants, researchers examine how toxic chemicals can reduce fertility in both humans and wildlife, and how these effects are worsened by climate change.


In short:

  • Animals - including insects, fish, reptiles, birds, humans, and other mammals - are constantly simultaneously exposed to synthetic chemicals and the impacts of climate change, including rising temperatures.
  • Both of these stressors can harm fertility, and many of the impacts found are similar across species, such as effects on sperm and eggs.
  • The stress caused by these exposures also impacts overall health, harming animals’ ability to adapt to a changing environment and worsening global biodiversity loss.


Key quote:

“To build a sustainable future, we must recognize that chemicals, once released, don’t simply disappear. Instead, they contribute to the larger issue of driving humanity towards the exceedance of planetary boundaries when considered in combination with climate change and other planetary-level impacts.”


Why this matters:

While climate change and toxic endocrine disrupting chemicals (EDCs) are both individually well-established as health threats, few studies have examined the implications of the widespread simultaneous exposure experienced by humans and wildlife. Many EDCs can also impact health across multiple generations, meaning their harm continues long after the original exposure. To better tackle the issue of EDCs, the authors of this study emphasize the need for strong regulations that address chemicals by class, rather than individually.
