“The issue has gotten worse. So I don’t think that working on an issue for 30 years alone is what qualifies as — as what makes someone qualified to solve an issue,” Ocasio-Cortez said in a clear swipe at Feinstein.

“That said, there are a lot of people that have been doing this work for decades that have proposed ambitious solutions for years and have not been listened to,” she added. “So it’s not just, ‘I’ve been doing this for 30 years,’ so we need to listen to them because frankly people have been failing at the same things for 30 or 40 years. What we need to do is say, ‘What solutions have not been tried yet? And what ambitious scale have we not shot at yet.’ And let’s do it.”

During the live stream, Ocasio-Cortez also questioned whether people should still have children because of climate change and further warned that “we have one shot” as “thousands” of people are dying due to its onslaught.
