California farmers face environmental challenges from plasticulture

California farmers face a growing challenge in balancing the benefits of plasticulture with increasing environmental concerns. Since the 1960s, the use of petrochemical-based plastics—such as irrigation drip tape, mulch films, and greenhouse tunnels—has revolutionized agriculture by stabilizing soil temperature and controlling weeds and diseases.

However, the reliance on these materials contributes to rising plastic production and climate-warming pollutants from fossil fuel extraction. Furthermore, agricultural plastics often fragment into microplastics that accumulate in soil and waterways. Organizations like the California Marine Sanctuary Foundation are working with stakeholders to prevent these materials from entering oceans and bays while attempting to preserve the high yields provided by plastic technology.
