“Palas por Pistolas” by Pedro Reyes

Reyes, who originally is from Mexico City, collected 1,527 guns from the Culiacán area in Mexico. The project offered those who gave up their weapons, which were steamrolled publicly and melted, an exchange for a coupon that allowed them to buy electronics and appliances. Reyes used materials from the weapons to create shovels that were then used for planting trees.
