The correct answer is: d) All of the above
Many cities and towns in Tamil Nadu depend on rivers for their drinking water supply, industrial use, and sewage disposal.
- Drinking water supply: Rivers are a major source of drinking water for many cities and towns in Tamil Nadu. The water from rivers is treated and then supplied to households and businesses.
- Industrial use: Rivers are also used for industrial purposes. Industries use river water for cooling, cleaning, and other processes.
- Sewage disposal: Sewage is wastewater that comes from homes and businesses. It is treated before it is released into rivers.
The use of rivers for these purposes can have a negative impact on the environment. For example, the discharge of untreated sewage into rivers can pollute the water and harm aquatic life. The use of river water for industrial purposes can also pollute the water and lead to the depletion of water resources.
Despite the negative impacts, the use of rivers for these purposes is essential for the economic and social development of Tamil Nadu. The government is taking steps to reduce the environmental impact of these activities, but more needs to be done.
