Just hours ahead of the Democratic Party primary debate taking place in Houston this evening, 22 activist climbers from Greenpeace blockaded the Fred Hartmann Bridge in Baytown, Texas just after dawn on Thursday morning in order to shutdown, they said, “the largest fossil fuel thoroughfare” in the country and demand presidential candidates takes a bold stance in favor of the Green New Deal and a rapid renewable energy transition.

“We’re in a climate emergency created by fossil fuel CEOs and made worse by Trump. We can either take bold action to combat the climate crisis today or suffer the consequences—more floods, more mega-storms, and more fires—for years to come,” said Greenpeace USA executive director Annie Leonard in a statement.

With an average of 700,000 barrels of oil passing through the location the climbers have blocked every single day, the groups says that industry expansion plans—and a major U.S. push to export more fossil fuels in the coming years—could increase that amount to 2 million barrels in a matter of years.

The demonstrators were streaming live from the bridge in Texas in order to speak to people around the world about why the are blockading passage beneath the bridge. Watch:
