The Worldwide Fund for Nature (WWF) estimates that the 108,000 hectares of Portugal’s cork oak forests – the largest in the world – absorb about 10 million tonnes of carbon dioxide every year. It also adds that each cork tree sustains over 100 species of wildlife, including the critically endangered Iberian Lynx.
Portugal's cork forests are under threat, however, as aluminium screw caps and manmade stoppers have replaced natural cork in wine bottles. Next time you reach for a bottle at the supermarket choose natural cork. It's a simple step that helps preserve this small corner of the planet.
