Herbex Ltd.   - Environment

Fiji Islands have no active volcanoes and therefore no poisonous chemicals can accumulate in plants. On islands with active volcanoes plants can take up heavy metals from the soil which can reach dangerous high levels in plants.
The Fiji Islands have never been used as testing ground for nuclear detonations and are not used as a dumping place for industrial rubbish. Islands such as Tahiti which were used for under water nuclear test by French scientists are 6000 km away. Fiji has no heavy machinery or chemical industries that could spoil the environment, there are no autobahns, no oil refineries and no nuclear power stations.
Fiji's environment is balanced, not exploited and untouched, it is left as it has been for thousands of years. Rain forests cover most of the interior of the islands, climbing up hills and along rivers that are full of fish, prawns and crabs.
