Thousands of protesters gathered by Pershing Square early Saturday morning on Earth Day for the starting ceremonies of the inaugural March for Science LA, one of 500 satellites of the March for Science in Washington, D.C.
''Pussyhats,'' the pink knit cap that made its introduction as a symbol for feminism in the Women's March, were popular among participants at the March for Science as well.
As the morning rally wrapped up, marchers began mobilizing toward City Hall at around 11 a.m.
Although Trump supporters attempted to interfere with the protest, they were largely ignored by the marchers.
Two plug-in hybrid-electric polar traverse vehicles were at the vanguard of the march. Zero South, a South Pole expedition endeavor, retrofitted the fuel-guzzling Hummer H1s into zero-emission exploration machines.
The rear hatches of the PHE-PTVs were open to the public for those who needed shade or a break from the march.
The march mainly criticized the dismissive views taken by the Trump administration toward science, such as its plans for the Environmental Protection Agency budget cuts and the promotion of "alternative facts."
Protesters dressed up as the Santa Claus family said that only science can stop global climate change threatening the future of Santa's workshop in the North Pole.
The crowd congregate in front of City Hall. Speakers for the march included faculty members from UCLA, Cal State Northridge, Caltech and Moorpark College, in addition to individuals from both the private and public sectors.
Stephanie Pincetl, director and professor-in-residence for the California Center for Sustainable Communities at UCLA, gave a speech criticizing the federal government's decision to cut the budgets and funding for the EPA and other scientific organizations.
Marchers find shade under the belly of a media platform truck. Temperatures reached the high 80s during the peak of the march because of a recent heat wave.
UCLA students mingled with the other protesters as they put up a banner showing support for the March for Science. Students from other universities such as USC also participated in the march.
Activists return to Pershing Square, where an expo promoting scientific progress and activism was held, and sign petitions supporting Assembly Bill 14, which aims to bring more transparency to political campaign funding.
Three buses chartered by the Office of Undergraduate Students Association Council General Representative 3 ferried over 100 students to and from the march in downtown Los Angeles.
