What's Happening?
A massive patch of plastic-covered greenhouses in southern Spain has been identified as the most visible human-made structure from space, according to NASA. Located near El Ejido in Almería, these greenhouses cover approximately 32,827 hectares and are highly reflective, making them stand out in satellite images. The white plastic roofs contribute to a local cooling effect, despite the broader region warming. This discovery challenges the common belief that the Great Wall of China is the only man-made object visible from space.
Why It's Important?
The visibility of these greenhouses highlights the impact of modern agricultural practices on the environment. While they have transformed Almería into a productive farming region, they also generate significant plastic waste, posing environmental challenges. The cooling effect observed in the area suggests that such large-scale agricultural installations can influence local climate conditions. This finding underscores the need for sustainable waste management solutions and the potential for agricultural practices to affect climate patterns.
