Unpolluted

Our councillors are a fine upstanding lot, as pure and unpolluted as the lovely River Deel.

Before 1860, unpolluted tree trunks were often covered in pale lichens ; polluted trunks were bare, and often nearly black.

It is relatively unpolluted, and its landscapes composed of green hills, cliffs and rias are generally different from what is commonly understood as Spanish landscape.

Scientific expeditions in 1996 and 2006 described the lagoon and surrounding waters of Diego Garcia, along with the rest of the Chagos Archipelago, as "exceptionally unpolluted" and "pristine".

The beautiful, unpolluted beaches on small coral islands, blue waters and sunsets attract tourists worldwide, bringing in about $325 million a year.
