MK FOE members took part in Earth Hour - an environmental initiative celebrated around the world in March.
To mark the occasion, members switched off the lights for one hour and chatted about environmental issues over candle light.
Members made eco-pledges to reduce their carbon emissions. They vowed to take less flights, walk to work, and cut back on food miles (by purchasing locally produced food).
