The correct answer is: d) All of the above.
River pollution is a serious problem in Arunachal Pradesh. It is caused by a number of factors, including urbanization, industrial waste, and agricultural runoff.
Urbanization is the process of growth and expansion of cities. As cities grow, they require more land and resources. This can lead to the destruction of natural habitats and the pollution of rivers.
Industrial waste is another major source of river pollution. Factories and other industrial facilities often dump their waste directly into rivers. This can contaminate the water and make it unsafe for drinking, bathing, and fishing.
Agricultural runoff is also a major source of river pollution. When farmers use fertilizers and pesticides, these chemicals can wash into rivers and streams. This can pollute the water and harm fish and other aquatic life.
All of these factors are contributing to river pollution in Arunachal Pradesh. This pollution is having a negative impact on the environment and the people who live in the state.
Here are some additional details about each of the factors that contribute to river pollution in Arunachal Pradesh:
- Urbanization: As cities grow, they require more land and resources. This can lead to the destruction of natural habitats, such as forests and wetlands. These habitats are important for filtering water and preventing pollution. The destruction of these habitats can also lead to the loss of biodiversity.
- Industrial waste: Factories and other industrial facilities often dump their waste directly into rivers. This can contaminate the water and make it unsafe for drinking, bathing, and fishing. Industrial waste can also contain harmful chemicals that can harm fish and other aquatic life.
- Agricultural runoff: When farmers use fertilizers and pesticides, these chemicals can wash into rivers and streams. This can pollute the water and harm fish and other aquatic life. Fertilizers can also cause algae blooms, which can block sunlight and suffocate aquatic life. Pesticides can kill fish and other aquatic life, and they can also be harmful to humans if they are consumed in contaminated water.
River pollution is a serious problem that is having a negative impact on the environment and the people who live in Arunachal Pradesh. It is important to take steps to reduce river pollution, such as:
- Reducing the use of fertilizers and pesticides
- Investing in wastewater treatment facilities
- Protecting natural habitats
- Raising awareness about the problem of river pollution
