Kerry, Biden's Special Presidential Envoy for Climate, issued the warning during a green agenda conference in Washington D.C.

During the Department of Agriculture's (USDA) AIM for Climate Summit, Kerry told the audience that "we can't get to net zero, we won't get this job done, unless agriculture is front and center as part of the solution."

Kerry warned attendees that his and other world leaders' "lives depend" on farmers ceasing their operations.
