1. Sanders linked climate change to national security in a national discussion on terrorism.

In the first Democratic debate following the Paris attacks, CBS moderator John Dickerson of “Face the Nation” questioned Bernie Sanders about his plans to rid the planet of ISIL.

“In the previous debate you said the greatest threat to national security was climate change,” Dickerson began. “Do you still believe that?” 

“Absolutely,” Sanders said. “In fact, climate change is directly related to the growth of terrorism. And if we do not get our act together and listen to what the scientists say, you’re going to see countries all over the world—this is what the CIA says—they’re going to be struggling over limited amounts of water, limited amounts of land to grow their crops, and you’re going to see all kinds of international conflict.”

While his remarks may have baffled some people, Sanders is right to relate climate change to the growth of terrorism and create a national dialogue about this overlooked relationship. 

2. Sanders is the only anti-fracking candidate.

This week, the Sanders campaign released an ad exclusively to reiterate Bernie’s stance on fracking. Actress and activist Susan Sarandon, an ardent supporter, narrates the spot.

“Do Washington politicians side with polluters over families?” Sarandon asks. “They sure do, because Big Oil pumps millions into their campaigns. Bernie Sanders is the only candidate for president who opposes fracking everywhere. Why? Because fracking pumps dangerous cancer-causing chemicals into the ground and threatens our drinking water.”

New York banned fracking last June and votes in the primary April 19. However, fracking affects nearly half the nation’s states. 

3. Sanders sponsored the Rebuild America Act of 2015.

The Rebuild America Act of 2015 aims to improve watersheds, wastewater treatment, drinking water systems and create dams and levees to prevent flooding. It also seeks to set aside $3 billion a year to improve national parks, monuments, heritage areas and landmarks.

“The simple truth is that our infrastructure is collapsing and the American people know it,” said Sanders. “For much of our history, the U.S. proudly led the world in building innovative infrastructure. Today, the U.S spends less than 2% of GDP on infrastructure, less than at any point in the last 20 years.”
