Research on bisphenol A (BPA) in greenhouse agriculture in Spain shows concerns about its use in plastic sheets due to potential endocrine-disrupting effects. BPA is often used in polycarbonate plastics and epoxy resins, materials found in greenhouse coverings. While these plastics are widely used to improve crop productivity and reduce pests, BPA contamination poses environmental and health risks.

In Almería's "Sea of Plastic," greenhouse farms are shifting towards more sustainable practices like biological pest control and water-efficient drip irrigation. Additionally, innovations such as soil-free hydroponics and automated irrigation aim to make the system greener.

However, the environmental impact of plastic waste, including BPA-laden plastics, remains an issue. Policies and technologies need to address the disposal of BPA-containing plastics to protect health and the environment while maintaining agricultural productivity​ (Food Unfolded)​.
