It' s a fact that' s providing scientists with a new insight into the health of the countryside. Rivers drain over 80 of the Earth' s land surface. On their way to the sea, they support a huge variety of animals and plants, and give rise to some of the world' s greatest cities. But the health of Britain' s rivers is being threatened by a cocktail of pollutants, chemicals used in farming, industrial runoff and illegal dumping. With over 1, 000 rivers, keeping an eye on their health is a massive task. The Natural History Museum' s backing an inspired project to monitor and safeguard the health of Britain' s rivers, and to do that they' ve got the help of an army of volunteers, people who know the rivers probably better than anyone Britain' s anglers. |
