Which statement best evaluates the significance of modern
natural gas extraction on the physical environment? (1 point)
Hydraulic fracturing removes water resources from natural
sources.
Hydraulic fracturing does not lead to habitat
fragmentation.
Hydraulic fracturing does not contribute to the modification
of the atmosphere by releasing greenhouse gases.
Wastewater produced from hydraulic fracturing is clean
and can be released into Earth’s waterways.
The statement "Hydraulic fracturing removes water resources from natural sources" best evaluates the significance of modern natural gas extraction on the physical environment.
The statement "Hydraulic fracturing does not contribute to the modification of the atmosphere by releasing greenhouse gases" best evaluates the significance of modern natural gas extraction on the physical environment.
To evaluate the significance of modern natural gas extraction on the physical environment, we need to assess the impact of hydraulic fracturing (also known as fracking) based on the provided statements. Let's go through each statement:
1. "Hydraulic fracturing removes water resources from natural sources."
This statement suggests that water resources are being extracted from natural sources during hydraulic fracturing. This is significant because it can deplete local water sources and potentially impact ecosystems that depend on those water resources.
2. "Hydraulic fracturing does not lead to habitat fragmentation."
This statement implies that hydraulic fracturing does not result in the breaking up or fragmentation of habitats. This can be seen as a positive impact, as it indicates that the extraction process does not directly disrupt wildlife habitats or lead to loss of biodiversity.
3. "Hydraulic fracturing does not contribute to the modification of the atmosphere by releasing greenhouse gases."
This statement suggests that hydraulic fracturing does not release greenhouse gases, which are known to contribute to climate change and air pollution. If true, it implies that the extraction process has a minimal impact on the atmosphere.
4. "Wastewater produced from hydraulic fracturing is clean and can be released into Earth's waterways."
This statement indicates that the wastewater produced during hydraulic fracturing is clean and can be safely released into waterways. However, it is important to note that hydraulic fracturing wastewater can contain various chemicals and pollutants, including heavy metals, which can harm ecosystems if not properly treated.
Based on these statements, it is evident that statement 1 raises concerns about the impact on water resources, while statement 3 suggests a positive environmental aspect. However, it is essential to consider that the overall significance of natural gas extraction on the physical environment entails a comprehensive understanding of all the environmental factors involved, such as water availability, air pollution, and habitat preservation. It would be crucial to gather additional information and assess various studies, reports, and expert opinions to arrive at a more accurate evaluation.
