The correct answer is: d) All of the above.
Mining can cause environmental problems in Bihar such as deforestation, water pollution, and air pollution.
Deforestation is the removal of trees to make room for other uses, such as agriculture, development, or mining. When trees are removed, the soil is exposed to the elements and can be easily eroded. This can lead to flooding, landslides, and the loss of biodiversity.
Water pollution is the contamination of water bodies, such as rivers, lakes, and oceans. Mining can pollute water bodies in a number of ways. For example, mining can release sediment, chemicals, and heavy metals into water bodies. This can make the water unsafe for drinking, bathing, and fishing.
Air pollution is the contamination of the air with harmful substances, such as dust, smoke, and chemicals. Mining can pollute the air in a number of ways. For example, mining can release dust and smoke into the air. This can cause respiratory problems, heart disease, and cancer.
Mining can also have a number of other negative impacts on the environment, such as noise pollution, soil contamination, and land degradation.
