Sewage
Fish and wildlife will suffer and may even disappear from the river completely. Such pollution can also affect people, either causing diseases, or preventing people from leisure activities, or even preventing employment along the river.
do not waste water
That all depends on the nature of the infection and the treatmen for it.
The toxic waste from industries and domestic uses are disposed off in water untreated causing marine life a severe threat. Untreated sewage and farm waste that is disposed off in water causes putrefaction (growing of algae on the surface of water reducing oxygen count in water bodies)
Untreated sewage is waate product from factorries, nuclear facillities and untreated human waste. This waste is highly dangerous as it contains bacteria, virus, etc... This waste if mixed with river water or water system can cause large damage not just to human but aquatic life aswell. Treated sewage is sewage which is filtered and treated with chlorines and other chemical, after the process the water is ready to be mixed with river, etc. This water is even ready to drink.
people destroy streams and rivers i) discharging contaminated/polluted water or waste of domestic or industrial in to them
Untreated industrial waste is harmful to the environment. Releasing industrial quantities of waste into the environment, especially water, would be devastating to the natural ecosystem. Government legislation is designed to prevent this from happening and protect the environment.
No
It depends on who is doing the discharging. In the United States, the Environmental Protection Agency (EPA) regulates waste water discharge under the Clean Water Act. Other countries will have their own regulations. Unfortunately, the law is not always followed. If you have any questions or complaints you should contact your local authorities.
Well, if you are wasting water, one day there will be none left. Also, wasting water can cause global warming.
