Environment

The peninsula that constitutes mainland Greece is surrounded by more than 1400 islands, of which 169 are inhabited. The islands are divided into six groups: the Cyclades, the Ionians, the Dodecanese, the islands of the Northeastern Aegean, the Sporades and the Saronic Gulf islands. The two largest islands, Crete and Evia, do not belong to any group. Roughly four-fifths of Greece is mountainous, with most land lying over 1500m (4920ft) above sea level. Epiros and Macedonia, in northern Greece, still have extensive forests, but goat grazing, felling and forest fires have seriously denuded the rest of the country.
