Q4. What are the disadvantages of mining raw materials?
Answer:
Answers
Answer:
The disadvantages of mining include harm to air pollution, water pollution, loss of usable land, destruction of animal habitat, and harm to local communities and the miners themselves
Answer:
1.
- Mining pollutes the water of surrounding communities through cyanide contaminated waste ore and other abandoned mine waste including toxic metals and acid, which often get released into lakes, streams and the ocean, killing fish and contaminating drinking water.
2. -Mining for metals used in electronics is also extremely wasteful. For example, 80 tons of waste are generated from producing just one ounce of gold.
3. - Increasingly dangerous extraction methods are used to retrieve scarce oil resources in order to produce the plastics that are used to make electronic components like computer and cell phone casings.
4. - The mining of raw materials for electronic products—including silicon, aluminum, copper, lead, and gold—contributes to increased respiratory problems for workers, such as silicosis, tuberculosis, bronchitis, and lung cancer. Gold mines are the leading source of mercury air pollution in the U.S.
