Two protesters have glued themselves to a zebra crossing and shut down a busy street in Brisbane’s CBD.

The protest by a man and a woman in Queen Street began at 7.30am on Tuesday.

The man, who was named as Serge on social media, said the pair was protesting against “an extinction”.

“I can’t live with myself knowing that’s happening and not doing anything about it,” he said.

His co-protester, named as Ebony by the action group Extinction Rebellion Australia, said she was “not fighting, I’m speaking up for mother Earth”.

Police and paramedics were working to remove the pair late on Tuesday morning.

Spokesman Greg Rolles said Extinction Rebellion wanted governments to take action against climate change.

“What we’ve got here are two brave protesters who have put their own livelihoods on the line to try and protect our future,” Mr Rolles said.

“They’ve taken positions on the road that is going to be hard for police to remove.”
