For those
of us who live in large metropolitan areas or smaller industrial cities, will the
Trump administration be harmful to our health? The new president, it appears,
intends to gut environmental regulations, including the Clean Air Act of 1990. In
Los Angeles, long known for its dubious air quality, things may get a good deal
worse.
In a January 31 Los
Angeles Times article, Melissa Healy reported on a correlation between
extensive exposure to smog and dementia, particularly among older women. For
this demographic, Healy noted, “breathing air that is heavily polluted by
vehicle exhaust and other sources of fine particulates nearly doubles the
likelihood of developing dementia.” And for women who carry the APOE4 gene,
which makes it more likely to develop Alzheimer’s, the combination of genetics
and environment can be toxic, hastening the disease’s progress. Unlike diseases
such as asthma, where the role of poor air quality is well understood, much
still needs to be learned how air pollution can lead to Alzheimer’s or other
forms of dementia.
The study that Healy drew on appeared in the journal Translational Psychiatry. She noted that
three biomedical research methods were deployed, and all revealed high levels
of “very fine air particles” caused by cars and other vehicles. Smog isn’t the
only culprit. Proximity to power plants also can be a factor, as can frequent
exposure to the burning of wood. As Healy noted, studies involving laboratory
mice breathing polluted air in ten freeway locations in Los Angeles led to
clumps of amyloid plaque, the protein deposits in the brain that are a common
feature of Alzheimer’s.
A study published in 2011 in the British medical journal The Lancet found that people living near
congested highways were at far greater risk of having a stroke or developing
Alzheimer’s than people who didn’t. Could the people who live in the shadow of
a busy highway do so because they can’t afford to live elsewhere? As Healy
reported, the noted Alzheimer’s researcher Dr. Samuel Gandy at Mt. Sinai Hospital
in New York was the first to determine that air pollution could lead to “cell
death, inflammation and the build-up of amyloid protein” in the brains of mice.
This is not the first time that a presidential
administration has been indifferent, even hostile, to science. Ronald Reagan, I
submit, initiated the trend. The Gipper deserves credit for his role, opposite Soviet
Premier Mikhail Gorbachev, in bringing the decades-long Cold War to a peaceful
conclusion. But each of his Republican successors, with the exception of the
honorable George H.W. Bush, has seemed not only uninterested in science but
hostile to it. Global warming a hoax? How so? Who could stage such a “hoax”?
Who would benefit from it? Some international cabal? The Democratic Party? I
don’t think so. As a friend of mine commented during the disputed 2000
election, “The Democrats can’t even steal an election!” As far as I can tell,
staging global warming is way beyond the Democrats’ portfolio.
What the Trump administration is really attacking is the values
of the Enlightenment, the era that began in the seventeenth century and, in
America, reached full flower in Thomas Jefferson’s Declaration of Independence
in 1776. Unlike in earlier centuries, in other nations, there was no magical
thinking in the founding of the United States. “Alternative facts,” as Trump’s
spokewoman Kellyanne Conway suggested, are not facts. Their correct names are
“lies.” If you don’t believe me, consult the works of George Orwell. Start with
his essay “Politics and the English language,” and, if you can stomach it, take
on his bleak dystopian novel 1984. It’s
hard not to feel that the president of the United States is living in an
alternative universe, in which facts are fungible, if not just made up out of
full cloth.
