In this Sunday, March 3, 2019 photo, a general view of greenhouses known as "Sea of Plastic" is seen in El Ejido, a municipality of Almer??a province, in the autonomous community of Andalusia, Spain. The plastic covering intensifies and traps the heat while maintaining humidity. That allows farmers in this sunny region to harvest fruit and vegetables one month earlier than they would be able to if they were growing in open fields. It also means farmers can double or even triple the number of harvests per year. (AP Photo/Emilio Morenatti), APTOPIX
