Tires do not decompose. Left sitting in the sun, they release methane into the air, and when the heavy metals and other chemicals used to make them leach into the soil or water, they kill plants and harm terrestrial and aquatic ecosystems.
Tire dust kills coho salmon inhumanely–the chemical 6PPD-quinone breaks down the blood-brain barrier, causing confusion, suffering, and death.
And tires are a major source of micro plastics. It is estimated that tires in the U.S. alone produce about 1.8 million tons of microplastics each year.
Tires do not belong in wetlands.
