Answer:
Humans directly change the dynamics of the water cycle through dams constructed for water storage, and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand.
Fossil fuel production is another human activity that places considerable strain on drinking water — and not just because fracking and coal mining use a great deal of water, but because their waste products can pollute groundwater, and therefore drinking water, as well.Water resources face a host of serious threats, all caused primarily by human activity. They include pollution, climate change, urban growth, and landscape changes such as deforestation. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources.
