Steffen said the impact of human activity was already being felt on a planetary level on the carbon, water and nitrogen cycles, citing as an example that people now generate more reactive nitrogen. Humans can have a major impact on freshwater systems through water overuse the same waterways that support wildlife and plants also provide municipal water for cities and towns, and when consumption outstrips the natural regeneration of these waterways, it can negatively affect the ecosystem.

Human influence on the water balance human activity has the potential to indirectly and directly affect water quantity and the natural flow regime of a river system indirect impacts to the hydrologic cycle can result from land-use changes. The problem nutrient pollution explained too much nitrogen and phosphorus in the water can have diverse and far-reaching impacts on public health, the environment and the economy. Also, when latrines are placed on the banks of the river, human faeces can contaminate the water this gives rise to water-borne diseases such as cholera, gastro-enteritis, hepatitis, dysentery and typhoid.
