The hydrosphere is the sum of all water on Earth and the water cycle that distributes it around the planet. It’s because of the hydrosphere that life flourishes on Earth. Human activity has many impacts on water on Earth, including pollution, warming and changes in run-off. Learn more about the implications from a scientific viewpoint.
The state of the seas and oceans will be discussed, with particular emphasis on pollution, and acidification.
The keyword here is Sea Level Rise, and its associated consequences for marine wildlife and coastal communities.
The impacts of large-scale dams, deforestation, pollution, melting glaciers on crucial streams and river basins will be presented. An example is the Tibetan Plateau, which feeds the major rivers in South, South-East, East and Central Asia providing water for 2 billion people.
