How does water pollution relate to other environmental problems?

how does it relate to other issues such as, global warming, deforestation, acid precipitation, ozone depletion, etc. etc.?|||At a high level, they are all caused by human activity, often at the same time. For example, a factory might emit carbon dioxide (a greenhouse gas -%26gt; global warming) as well as sulfur dioxide (which contributes to acid rain) while it produces some redwood furniture (from deforestation) and the chemicals they treat it with end up in the water (water pollution).





Deforested areas have a lot more surface water runoff, which can concentrate pollutants.





Ozone depletion increases the amount of UV radiation that reaches the Earth's surface, which can damage crops. This necessitates the use of more fertilizer, and probably increases the crops' susceptibility to infestation, requiring herbicides and pesticides. These chemicals contribute to water pollution.
