Two thirds of college students believe climate change is an “existential threat” to their generation, but fewer than one in five are willing to give up their smartphones to help, a recent poll found.

More college students would sacrifice having children and eating meat before giving up their cellphones, according to a poll published Aug. 13 from the Young America’s Foundation.

The survey, facilitated by Echelon Insights, asked 812 college students in mid-July about a wide variety of topics, including environmental issues, politics, President Joe Biden, the economy and student loan forgiveness.
