There is a region in southeastern Spain called Almería. If you pull it up on satellite imagery, you will assume the screen has glitched. A vast, blinding white scab where a landscape used to be.
It's not a glitch. It's 64,000 acres of plastic greenhouses. So much plastic sheeting that it is, genuinely, visible from space. The entire region has been wrapped in industrial farming film to grow tomatoes, peppers, cucumbers and lettuce for European supermarkets in January.
The plastic has created its own microclimate. The reflective surface is so vast it has measurably lowered local temperatures by bouncing sunlight back into the atmosphere. Scientists have a name for it. The Albedo effect of Almería. The only place on earth where human activity has cooled the local climate, and they did it by accident, while building the world's largest open-air plastic factory.
The plastic itself is single-use agricultural film. It sits in UV light for three to five years, degrades into microplastics, blows into the Mediterranean, and ends up in the ocean and the soil. Every year, 45,000 tonnes of plastic waste is generated just from replacing degraded greenhouse covering. Every year. Just the covering.
Inside, workers from Morocco and sub-Saharan Africa labour in 45°C heat for €30 a day. No contracts. No rights. Spraying crops with pesticides at concentrations that would be illegal on outdoor fields. Ventilation: minimal. Chemical exposure: constant. The aubergine looks lovely.
The groundwater underneath Almería is so contaminated with agricultural runoff that it has been declared unusable. The region now imports water from elsewhere in Spain while sitting on top of a poisoned aquifer it created. The land that was meant to feed Europe more efficiently has become a place that needs water flown in to keep the show running.
And this is what supplies your fresh vegetables in January. Grown in plastic factories. By exploited workers. Using groundwater they have already destroyed. Wrapped in more plastic. Shipped across Europe. Refrigerated the whole way. So a person in Manchester can have a tomato in February that tastes of nothing.
But sure. Cattle grazing on Scottish hills are the environmental problem.
Pull the satellite up. Have a look. Then tell me which system is the one that needs explaining.
