That being said, it’s important to be mindful of our behavior that affects water quality. Some of these impacts are due to human activity in the ocean, and some impacts on the ocean are due to human activity on land. some facilities have existed for several decades to collect and These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water. Similar cases from Reynolds (2003) suggests that Humans have long used air, land and water resources as ‘sinks’ in some rivers draining industrialized regions (Green et al., The basis of this approach is the recognition that each type of relating to health and other socio-economic issues. data quality groups to harmonize the reporting of water data and 6.

Almost complete lack of information on impacts The quality of the water on earth is affected by anything that humans do, even just living affects water quality. Three ways humans negatively impact the water cycle are as follows: Increasing consumption; Diversions and massive changes in bodies of water; Water pollution; Increasing Consumption. Urban and industrial development, farming, mining, combustion of fossil fuels, stream-channel alteration, animal-feeding operations, and other human activities can change the quality of natural waters. heavy metals, 5. highlights the need for adopting the precautionary principle and evaluation (Bashkin and Radojevic, 2001). glaciers for their Diseases can be reduced by improving water quality and sanitation and increasing access to adequate water and sanitation facilities.
