It has long been known that nutrient pollution – the overloading of chemicals such as nitrogen and phosphates from sources such as agricultural fertilisers – can have potentially harmful effects on freshwater ecosystems.  In particular, eutrophication – the rapid growth of algal ‘blooms’ – can starve the aquatic environment of light and dissolved oxygen, prompting shifts in the form and function of the ecosystem, and potentially causing collapses in populations of other freshwater plants and animals.

The Lourens River – an unprotected natural environment?
