(UNDATED) - Operation Free is a coalition of veterans and national security organizations touring the nation to bring awareness to threat that climate change poses to America's national security.
Military veterans like Chuck Tyler are onboard holding roundtable discussions with students and veterans.
The tour stopped at the IUPUI on Wednesday and talked about the energy threat to food security which could impact Indiana farmers.
The tour is making seven stops in Indiana with a number of Hoosier veterans on board.
According to the group the threat comes from many sides including health security, our national oil addiction and from terrorism.
They say water shortages, agricultural suffering, mass migrations, and natural disasters could destabilize governments around the world, leaving many nations powerless to stop the spread of extremism.
The group is urging people to contact their legislators to pass clean energy legislation.
