For my new video, I asked people on the street, “If you could spend $30 billion trying to solve the world’s problems, how would you spend it?”

“Build houses…address homelessness,” said a few. “Spend on health care,” “redistribution.” The most common answer was “fight climate change.”

Really? Climate change is the world’s most important problem?

“It’s not surprising if you live in the rich world,” says Bjorn Lomborg, president of the Copenhagen Consensus Center.
