Harnessing of nuclear energy often causes ________ pollution

Air
Water
Thermal
Noise

The correct answer is: Air pollution.

Nuclear power plants release radioactive pollutants into the air, including radioactive iodine, cesium, and strontium. These pollutants can be carried by the wind and rain to other areas, where they can contaminate food and water supplies.

Air pollution from nuclear power plants can cause a variety of health problems, including cancer, respiratory problems, and birth defects. It can also damage the environment, harming plants and animals.

The other options are incorrect because:

  • Water pollution is caused by the release of harmful substances into water bodies, such as rivers, lakes, and oceans. These substances can come from a variety of sources, including industrial waste, sewage, and agricultural runoff. Water pollution can cause a variety of health problems, including gastrointestinal problems, reproductive problems, and neurological problems. It can also damage the environment, harming fish and other aquatic life.
  • Thermal pollution is caused by the release of warm water into rivers, lakes, and oceans. This warm water can disrupt the natural balance of these ecosystems, harming fish and other aquatic life.
  • Noise pollution is caused by the excessive or unwanted sound that can harm human health and the environment. Noise pollution can cause a variety of health problems, including hearing loss, stress, and sleep problems. It can also damage the environment, disrupting wildlife and interfering with communication.
