Hundreds of people gathered in Los Angeles on Sunday to protest against climate change and show support for activists demonstrating against the construction of an oil pipeline in North Dakota.
Several Hollywood stars, including Mark Ruffalo and Susan Sarandon, were among the more than 800 people who attended the climate rally in MacArthur Park. Rallygoers carried signs urging to "shut it all down now" and chanted slogans like "water is life."
"Not only is it an environmental, but it's a problem in terms of social justice," Sarandon told the rally. "We can do it. We can stop fracking. We can stop the pipeline. But really it's only because of great numbers of people."
