A land awash with nutrients - the problem of eutrophication.

From: Chemistry and Industry | Date: June 3, 1996| Author: | Copyright information

The leakage of plant nutrients into waterways as a result of human activities began 5000 years ago, and is now becoming an increasing problem

In 171AD, Lucius Cassius Longinius, third consul, made a road out of Rome so that he could move the army quickly to discourage dissidence among the rural people. Building roads then, as now, disturbed a swathe of land much wider than the eventual roadbed. By chance, or the propensity for Roman road builders to move in straight lines, Lucius built his road through the catchment area of a small lake, the Lago di Monterosi. The lake ...
