They came on kayaks and on bikes. They hunkered down in hammocks and on train tracks. They marched at refineries and did morning yoga at mines.

For nearly two weeks, demonstrators on six continents gathered to protest climate change — and, in particular, the fossil fuel industry.

In Washington state, 52 people were arrested Sunday after they camped out on train tracks servicing oil refineries in northern Puget Sound, Ashley Ahearn of member station KUOW reported for our Newscast unit.

One of the arrested protesters, 24-year-old Elizabeth Claydon, told Ahearn she'd never been arrested before. "Corporations are not complying and not changing and government is not acting fast enough, so I'm going to continue to do this as long as I need to," she said.

The march in Washington was part of a coordinated effort called Break Free 2016, which included protests and marches in Australia, Germany, Brazil, Turkey, Indonesia and Nigeria, among other places.

The organizers say that between May 3 and May 15, tens of thousands of people participated around the world.

More than a week ago, in Australia, hundreds of protesters on kayaks and other boats blockaded the Newcastle port — one of the world's biggest coal export ports, according to The Guardian.

In the U.K., activists reportedly shut down the country's largest open-pit coal mine.

In Germany, they broke into a coal-fired power station and blockaded the nearby Welzow Sued open-pit mine.

Last week in Nigeria, protesters reportedly gathered at the country's first oil well. And this weekend in Albany, N.Y., protesters targeted crude oil trains.

In Chicago, they marched on a BP refinery, and in Los Angeles, they took to the streets.
