The document summarizes a campaign to promote environmental protection at El Recero School in Lebrija, Spain. The campaign involved several activities over 6 weeks, including painting murals and posters, collecting student signatures on an "Ecological Contract", sending postcards, and distributing a questionnaire. The contract encouraged environmentally friendly behaviors like recycling, walking to school, turning off lights when not in use, and taking shorter showers to save water and energy. The goal was to educate students on small everyday actions they can take to help the environment.
