Cancer mortality rates (deaths per 100,000 people) were determined for counties in Appalachia (Kentucky, Tennessee, West Virginia, and Virginia). Counties were identified as a mountaintop removal (MTR) area if there was at least one MTR mine, 40- 320 acres in size with at least 10 acres of removed ridge top. Counties with mines other than MTR mines or counties with no mines were also evaluated. NOTE: On the bar graph, the letter "a" next to a bar indicates it is significantly different from the "No mining" group for a given cancer; the letter "b" indicates it is significantly different from the "Other mining" group; p < 0.05. Why are the mortality rates for lung and colon cancer shown in a different graph? The researchers reviewed more data for lung and colon cancer. The lung and colon cancer data came from a different cancer study. Lung and colon cancer are faster-acting types of cancers. Lung and colon cancer rates are much higher than the other types of cancer.
The 1973 Clean Water Act requires that streams altered by mountaintop removal (MTR) mining be reclaimed to reduce the effects of mining on stream ecosystems. To reclaim streams, concrete- and stone-lined ditches are created to act as functional waterways. What ecological functions do the artificial streams lack to compared to natural streams? They do not hold water on the same seasonal cycle. They do not aid in flood control. They do not process contaminants out of water. They do not connect to natural bodies of water. They do not support the same aquatic life.
In carbon capture and sequestration (CCS), carbon dioxide (CO₂) emissions from coal-fired power plants are trapped within a solvent, reducing the CO₂ emissions released into the atmosphere. The CO₂ is then separated from the solvent and sequestered underground. After capture, which types of underground environments are suitable for CO2 sequestration? unminable coal seams deep saline formations depleted oil and gas reservoirs oceanic sea vents swamps and marshes
