Is the United States "empty" because there's not a billion plus people already living here? Journalist Matthew Yglesias argues that's the case. Not convincingly, but that didn't stop him from writing an entire book on the subject.
Around the time of the first Earth Day in 1970, when there were 130 million fewer Americans than at present, environmental scientists, activists and even politicians were outspoken and unequivocal on the threat posed by a growing U.S. population. Yet neither the Trump administration nor its harshest environmentalist detractors are willing to recognize or resolve the greatest threat to all wildlife in the United States: large-scale habitat loss from incessant U.S. population growth.
