HARRISONBURG, Va. (WHSV) -- A Virginia man is walking 3,000 miles across the country from LA to Washington, DC. Jerry Stewart, who's from Loudon County, will be one of hundreds doing the Great March for Climate Action.
"One of its goals is to push our elected leaders to act on the climate," said Stewart.
Stewart believes that climate change is a social justice issue.
"Those who are most affected are the poor, children and future generations don't have a voice, so those people who are able to speak out, must," said Stewart.
Stewart says changing infrastructure is the answer.
"Switch to a sustainable energy economy, one where we use solar, wind," said Stewart.
Peter Jackson with the Chesapeake Climate Action Network produced "Sea of Change", shown at the event. The film says global warming is driving sea levels higher.
"What we have to do is we have to look and see how it is that the largest polluter in our state is producing our energy and it is primarily through fossil fuels," said Jackson.
Though, scientists don't all agree that our planet's temperature change is primarily caused by human activity.
Some, including physicist Fred Singer with George Mason University, argue that it's more likely that climate change is caused by "solar magnetic activity" and by "changes in ocean circulation."
Despite that, for Stewart, pushing for policy change, starts with a march.
"The more we do, the less negative impacts we're going to see in the future," said Stewart.
