The challenges posed by climate change could be solved by humans living on other planets, Gary Johnson, the Libertarian presidential candidate and former governor of New Mexico, has told ABC News.
"We do have to inhabit other planets. The future of the human race is space exploration," he told the broadcaster in an interview late Sunday.
Johnson was asked about a comment made back in 2011 where he said that "in billions of years the sun is going to actually grow and encompass the earth." Johnson told ABC on Sunday that the remark had been a joke.
