The activities of modern humans have drastic effects on the hydrosphere. For instance, water diversion, human development, and pollution all affect the hydrosphere and natural processes within. Humans are withdrawing water from aquifers and diverting rivers at an unprecedented rate.
The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
Chemicals and heavy metals from industrial wastewater are also toxic to aquatic life. They can shorten an organism's life span and its ability to reproduce while also endangering humans, since humans may feed on these organisms and any toxic impacts on these organisms may adversely impact humans.

The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
The human-caused changes to the water cycle will increase hydrologic variability and therefore have a profound impact on the water sector and investment decisions. [9] They will affect water availability (water resources), water supply, water demand, water security and water allocation at regional, basin, and local levels. [9]
The diagram also shows how human water use impacts where water is stored and how it moves. [1] The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
The effects of climate change are impacting humans everywhere in the world. [233] Impacts can be observed on all continents and ocean regions, [234] with low-latitude, less developed areas facing the greatest risk. [235] Continued warming has potentially "severe, pervasive and irreversible impacts" for people and ecosystems. [236]
