Spain's Almería Greenhouses Visible from Space Highlight Environmental Challenges
In Almería, Spain, a vast network of greenhouses, known as the 'Sea of Plastic,' is visible from space due to their bright white roofs. These greenhouses cover over 40,000 hectares and are a major source of fruits and vegetables for Europe. The reflective polyethylene roofs create a shimmering effect, making them easily identifiable from orbit. While the greenhouses have transformed the region into a significant agricultural hub, they also pose environmental challenges, including plastic pollution and water scarcity.
