Water Pollution is a serious problem in the global world. The world environmental problems include loss of species and biodiversity, toxic chemicals and hazardous waste, ozone depletion, trans boundary air pollution and climate change. It happens when toxic substances enter into water bodies such as lakes, rivers, oceans and so on, getting dissolved in them which degrades the quality of water. Increasing population, urbanization, environmental degradation, changing agricultural sectors, etc., are some of the factors that are determining the future water demands.

Promoting environmental sustainability
Sustainable development in any society is an access to initiate a good standard of living for the populace. It aims at providing solutions to the economic, environmental, and societal challenges without posing a threat to human and environmental future development, that is, we must consider the future as we make present decisions. Also, these include social progress and equality, environmental protection, conservation of natural resources, and stable economic growth.
Effects and challenges
Water is an essential and general need of life with an undeniable effect directly or indirectly. All industrial, environmental, and metabolic processes are water dependent. In living organisms, water plays a number of roles such as solvent, temperature buffer, metabolite, living environment, and lubricants. Water, however, is said to be polluted when some of the water quality parameters have been hampered by unguided and irregularities from several anthropogenic activities, thus rendering water unfit for intended use.
Thus, after analysing the above-mentioned cases, we find that the Supreme Court currently extends the various legal provisions relating to the protection of the environment. In this way, the justice system tries to fill in the gaps when there is a lack of legislation. These new innovations and developments in India through judicial activism open the many approaches to helping the country. In India, courts are extremely aware and cautious about the particular nature of environmental rights, as the loss of natural resources cannot be renewed. There are recommendations that need to be considered.
