Until three years ago, you could have called me a scientist, educator, or mentor—but not an activist or marcher. Over time, however, I have recognized that I have the knowledge, privilege, and responsibility to act and march to protect the communities I love.

Early in my studies at MIT, I believed I could only contribute to solving the climate change dilemma by creating energy efficient and renewable energy technologies. This all changed after I participated in the first People’s Climate March in New York City in 2014. Now I am convinced that activism as a citizen-scientist is an equally valid way to highlight problems and advocate for solutions.

"If we are truly going to protect and empower our urban and rural communities from an environmental and health hazard as big as climate change, we need everyone to fight."

Attending the People’s Climate March was a life-changing experience. I marched alongside more than 310,000 individuals in the heart of NYC to call our world leaders to start taking serious action against climate change. That day I understood the difference I could make by becoming part of something greater than myself.

Furthermore, I recognized that staying on the sidelines to claim “objectivity” as a scientist was not an option. Sitting this fight out would mean staying silent while I watched disenfranchised and vulnerable communities suffer. By staying silent, I would be denying my own relationship to these communities, my own humanity, and I would be ignoring my responsibility as a citizen to fully participate in the democratic process.

As a son of poor immigrants from Central America who grew up in the inner city, I am painfully aware that poor communities are disproportionately affected by environmental threats like climate change. For example, the tragic outcomes of Hurricane Katrina overwhelmingly affected low-income and minority communities. Of the 250,000 evacuees that arrived in Houston, and were housed in shelters, 90 percent were African American, of which 6 in 10 had incomes below $20,000. Today we see similar structural inequalities and issues arising from water contamination in Flint, Michigan, and in the potential impacts of the Dakota Access Pipeline on the drinking water of the Standing Rock Sioux Tribe.

Understanding that climate change, like other environmental problems, is an issue of equity and justice has further motivated me to take action. As Einstein once said, “those who have the privilege to know have the duty to act.” I believe scientists, engineers, and experts should be working not just to address climate change, but to do so in a way that empowers communities that do not have an equal seat at the negotiation table.

Therefore, as I prepare for the March for Science on April 22 and People’s Climate March on April 29, I want to remind my colleagues that science or technology alone will not solve the major challenges facing our society. Peaceful marches and protests are valid and necessary means of creating the societal momentum needed to make change. More importantly, if we are going to address these challenges in a fair and equitable way, we must use our privilege to empower and uplift the most marginalized communities in society.

If you can identify with me as a scientist, educator, person of color, or son or daughter of immigrants, then I ask you use your voice to speak up. For me that means marching to protect the communities I care about. I ask that you do the same. If we are truly going to protect and empower our urban and rural communities from an environmental and health hazard as big as climate change, we need everyone to fight.
