Geopolitical strategist and bestselling author Peter Zeihan warns that declining immigration could have significant consequences for U.S. agriculture and the broader economy. Known for his work on global demographics, energy, and security—and followed widely through his books, newsletter, and YouTube channel—Zeihan argues that America’s historic strength has come from welcoming newcomers. With the U.S. population now slipping, he says agriculture-dependent regions may feel the impact first as labor shortages deepen. Zeihan will expand on these trends as a keynote speaker at the 2026 Land Investment Expo.
