Activists will gather in Washington D.C. and locally on Saturday to protest President Trump's agenda on climate change and the environment.
Tom Crowe from Northampton is part of a group who spent eight days biking to Washington for the People's Climate March. He said peddling there is symbolic.
"The bicycle is one of the most fuel-efficient modes of transportation that humans have ever devised," Crowe said. "It only relies on carbohydrates. It doesn't need fossil fuels directly."
But Crowe said he'll be taking a bus back to western Mass.
While he's in D.C., a satellite march will be held in Springfield. Susan Theberge is involved with one of the groups organizing the local march.
"The impact of climate change -- as it becomes clearer and clearer -- there'll be a point when the federal government has to listen because the people's voices are so loud and so clear," Theberge said.
Marches are also taking place in Greenfield, Mass., Keene, N.H., and Wallingford, Conn.
