What do you say? L.A. Times has this story on today's front page (Dec. 4, 2020). I think we need to consider less driving and picking High Sierra locations closer to home, and parking closer to the main highways by practicing cross-country travel with significant elevation gain & return.
Here's the basics:
Scientists solve mystery of mass coho salmon deaths. The killer? A chemical from car tires

"""When officials in Seattle spent millions of dollars restoring the creeks along Puget Sound — tending to the vegetation, making the stream beds less muddy, building better homes for fish — they were thrilled to see coho salmon reappear.
But when it rained, more than half, sometimes all, of the coho in a creek would suffer a sudden death.
These mysterious die-offs — an alarming phenomenon that has been reported from Northern California to British Columbia — have stumped biologists and toxicologists for decades. Numerous tests ruled out pesticides, disease and other possible causes, such as hot temperatures and low dissolved oxygen.
Now, after 20 years of investigation, researchers in Washington state, San Francisco and Los Angeles say they have found the culprit: a very poisonous yet little-known chemical related to a preservative used in car tires."""
