HUMANS AND THE HYDROSPHERE

Humans use large amounts of fresh water from our streams, lakes and underground sources. In some cases, these withdrawals have led to groundwater depletion or the movement of ocean water into the aquifers. Humans modify the quality of freshwater. Do you drink bottled water? Do you filter your drinking water? WHY? Humans add nutrients like water-soluble phosphates / nitrates, and other pollutants, disease-causing organisms, acids, salts, and toxic metals like mercury and lead, sediment or suspended matter mostly when soil is eroded from land, heat, genetic pollution ( introducing non-native species)...How have humans changed the oceans? How has technology affected glaciers?

Just as humans have an effect on the waters of the hydrosphere, these waters can also affect human activity. El Nino'
The moderating effect on climates of oceans and lakes, ample amounts of rainfall and/or snowfall, along with a lack of extremes in temperatures, are ways in which water could affect human activity.
