"We must make a sustained effort to engage the public and to make science meaningful, relevant, and captivating". "I don't think we should see this as a one-off event".
Prof. Rebecca Nelson, plant pathology, plans to attend the march to express her discontent with the budget cuts due to the repercussions it would have for scientific research in the future.
"[I'm] marching to support women in science, the scientific method, and increased science funding for progressive solutions to the problems we face as citizens, today".
For me, this is really all about climate science because I'm a climate scientist and the issue that really resonates with me is that we need to move past this false debate about whether climate change is real so that we can have the real debate as a society about how we're going to fix it.
"Because attacks on science don't just hurt scientists, they hurt scientists' ability to protect the people, and climate change epitomizes that", Supran said. That number grows with each passing year.
I won't be marching.
Dr. Ayana Elizabeth Johnson, a marine biologist who has served as one of the march's leading organizers, added: "Science has never been independent from politics".
US President Donald Trump's attacks on scientists and his denial of climate change have been worrying researchers across the world.
Scientists are concerned about policies that go beyond simple budget cuts.
"Anywhere between 97 percent and 99 percent of publishing scientists, depending on the study that you look at, [are] all on record".
The protests are often fueled by those with left-leaning political views who were surprised by Trump's victory but have not been quelled by his policies and actions since taking office.
Keeping our air and drinking water clean and wasting less water, energy and food shouldn't be controversial politicized issues.
Trump is the unifying factor for both marches, both in how they came together and what messages they'll promote. Merced Art Hop will host themed activities event to showcase the city's scientists and their work, organizers said.
Holt, who heads the American Association for the Advancement of Science, described the trend as "appalling" and said it has driven anxiety to new heights.
The president has said he wants to loosen environmental regulations to "eliminate federal overreach, restore economic freedom and allow our companies and our workers to thrive and compete on a level playing field".
Has your work been impacted by any specific policy changes by the Trump administration?
Zerhouni said there are about 300,000 scientists in the USA and he expects numerous younger or aspiring scientists to be discouraged from the field if funding dries up. Among other things, we need to reinvent much about the way we function in order to create an economy with lower carbon emissions.
"I would expect that perceptions of both scientists and the nature of science might shift, at least temporarily", Amanda Diekman, a psychologist at Miami University in OH who studies stereotyping, told The Washington Post.
"I hope the new administration will appreciate not only the value of evidence-based science in government affairs, but also the fact that the scientific enterprise, which is based on the global exchange of people and ideas, is within America's national interest and is fundamental to global stability and prosperity". A week later, April 29, another large gathering - the People's Climate March - is planned in Washington. See People's World story here. Other scientists agree that the march is the ideal platform to unite scientists from all backgrounds to fight the global challenges to science together. "I don't think that is what our representatives should be doing".
