Why I Marched for Science
Earth Day is now a worldwide event commemorated in almost 200 countries. This is a clear statement that we are all in it together and that a healthy environment is a common good. Today this shared commitment is at risk; we must reaffirm the important underpinnings of those vital roles of government.
As a physician, former Vermont Commissioner of Health and soon to be Peace Corps volunteer in Sub-Saharan Africa, I have and will continue to rely on science as my guide for medical and policy decisions. In the age of Google, fake news, and deep distrust of government institutions, it's easy to lose track of the truth that science brings us. This is the case whether the topic be vaccinations, climate change or the newest "Ebola" that comes knocking on our door.
Health and medicine, like the environment, rely on science to drive good policy. Given this, what is my charge to those of us who are scientists?
Become an activist — something we may not be comfortable with or that we've been trained to do, but that is vital at this point in our country. Spell out in plain language what the science says, even when it may not be popular. Be transparent with any potential conflicts we may have and shine a light on potential conflicts and sources of support behind those on the other side of issues — pharmaceutical companies, energy, or tobacco, for example. Importantly, clearly state but do not overemphasize areas of uncertainty.
We must be empathetic with dissent but firm in our conclusions on issues: climate change is real, vaccinations work, smoking causes cancer and heart disease, addiction is a brain disease and sugar-sweetened beverages cause obesity. Denial is based on an individual's strongly held beliefs and values — we must understand this as we work to make headway on important public health priorities.
Finally, do it over and over again. Repetition is an evidence-based strategy — and we have to do it together, as the whole is undoubtedly greater than the sum of its parts. I saw the strength in numbers during the most recent immunization debate in 2015. Don't get discouraged and lose the battle of wills. And remember that passion is important — but it's not "personal."
Science must speak truth to power and money in a factual, non-partisan way. In this era of Citizens United, it's a steep hill to climb and requires an "all hands on deck" effort on our part. Truthfully there is a lot of power in money.
Climate change is a human health priority and one of the key areas now under attack. Climate change is a certainty. How do we know this? Science and scientists.
In Vermont, as elsewhere, we have hotter summers, harsher winters, earlier springs and more precipitation. Just to cite one of many alarming changes: The temperature of Lake Champlain has increased 5 to 7 degrees in the past 50 years.
Extreme weather events occur more often. In 2011, I had been health commissioner only a few months when heavy spring rains caused rising rivers, evacuations and extensive road damage in Northern and Central Vermont. Lake Champlain waters rose, flooding playgrounds, homes and Burlington's downtown waterfront for weeks. But this was small potatoes compared to what occurred on August 28. Tropical Storm Irene flooded a large part of the state — we lost six lives, homes were destroyed, drinking water contaminated and at least 500 miles of roads and 200 bridges were damaged and impassable. Access to medications, hospital and health care was limited for a time. We bear the physical and emotional scars of Irene to this day. The May storm and Tropical Storm Irene were only two of the 18 federally-declared disasters in Vermont over the past decade.
Climate change means more illness and more deaths in Vermont. We've seen a dramatic rise in blue green algae blooms, drinking water contamination, ticks and Lyme disease, and more asthma. In 1988, when I came to Vermont, virtually all Lyme disease came in a car from Connecticut. Today we have some of the highest case rates of Lyme in our nation.
Climate change does not affect people equally. Everyone is at risk, but people who spend a lot of time outdoors, those with health sensitivities and people with limited financial and social resources are more affected.
Where do the greatest CO2 emissions on earth come from? China and the United States. Where will the greatest impacts on human health occur? Sub-Saharan Africa. There the health effects (famine, disease, drought and extreme heat) literally threaten human existence.
Here in the U.S., how many more Flint, Mich. or North Bennington will we see without a clear commitment to clean water for our citizens? In Flint it took a fearless pediatrician and scientists from Virginia Tech to expose the lead in the water that was endangering Flint's most vulnerable citizens. I met Dr. Mona Attisha-Hutt and she is a true hero. We all need to be like Dr. Attisha-Hutt, using science and raising our voices to confront power to protect our citizens' health and well-being.
There is hope — and we all can take actions to reduce the risks. Start by supporting science, listening to science, acting by science. Pay attention to the challenges to science and when you see them, clearly articulate the science as we know it, early and often.
When it seems to fall on deaf ears, do it again, louder. Do it as if your life depends on it — indeed it might.
