b) California

California was the first American state to ban plastic bags statewide, doing so in 2014. This environmental policy aimed to reduce litter, protect marine life, and lessen the impact of plastic waste on the environment. The statewide ban on single-use plastic bags at large retail stores was a significant step in environmental conservation efforts and reflected a growing awareness of the importance of sustainable practices. California’s initiative set a precedent for other states and regions in the U.S. and around the world, highlighting the role of state policy in environmental protection.
