Failure to ensue.

NEW YORK (CNNMoney) – Hundreds of environmentalists plan to “shut down” the New York Stock Exchange later Monday to protest the relationship between global warming and Big Business.

Scores of protesters had already gathered in lower Manhattan early Monday for an event dubbed #FloodWallStreet. They planned to march a few blocks north to Wall Street and stage a “sit-in” until forced to leave.

Their beef: the fossil fuels industry and other companies are profiting at the expense of the environment. The activists said they were willing to be arrested to drive home the link between global capitalism and worsening climate change.

“The climate crisis is fundamentally an issue of the economy,” one activist told CNN. “Flood Wall Street is an attempt to bring the problem to the doorstep of the people who are fundamentally responsible for the crisis we find ourselves in now.”

Organizers, who have not obtained permits, expect participants to be “arrested in droves.” Blue-clad protesters plan to unfurl a 300-foot banner and will inflate a 15-foot “carbon bubble,” according to a statement on the #FloodWallStreet website.
