"They work for me night and day," smiles Antonio Zamora, standing in his greenhouse. His minuscule employees are bugs that feed on the parasites threatening his peppers.
Zamora, like most of his colleagues, no longer sprays his crops with pesticides, instead hanging small bags of mites on the plants, leaving them to attack parasites while sparing his produce.
He owns two hectares (five acres) in the so-called "Sea of Plastic", some 30,000 hectares of greenhouses in southeastern Spain's Almeria province, where much of Europe's fruits and vegetables are grown.
