Step 1
Explain the potential environmental impacts of quarrying
Answer
Quarrying of limestone can lead to the destruction of natural beauty and habitats. It often results in the displacement of wildlife and can disrupt local ecosystems. Additionally, it may disturb areas of natural beauty, leading to visual pollution, and is often associated with dust pollution that affects air quality.
Step 2
Explain the potential environmental impacts of drilling
Answer
Drilling for natural gas can have significant environmental impacts, including the risk of methane leaks that contribute to greenhouse gas emissions. It may also introduce pollutants into the water supply, harming both ecosystems and human health. The noise and vehicular traffic associated with drilling can also lead to disturbances in local wildlife populations.
Step 3
Explain the potential environmental impacts of thermal decomposition of limestone
Answer
The thermal decomposition of limestone in a kiln releases carbon dioxide (CO2), which is a major contributor to climate change. The process can produce other harmful emissions, such as sulfur dioxide (SO2), which can contribute to acid rain and respiratory issues in humans. Additionally, particulate matter released during this process can pose health risks by aggravating respiratory problems.
