To assess which two actions would have the largest impact on total combined water use from all states, let’s analyze each option:
-
Develop additional solar and wind power plants: While renewable energy sources are essential for sustainability, this action may not directly impact water use significantly when compared to other options.
-
Monitor patterns in crop water use to ensure efficient delivery of water: Agriculture accounts for a substantial portion of water use. Better monitoring can lead to more efficient water use, potentially reducing total water consumption significantly.
-
Replace all toilets in public spaces with low-flow toilets: Toilets are a major contributor to water use in urban areas. Switching to low-flow models can lead to considerable water savings.
-
Encourage use of recycled materials and limit manufacturing of new products: This action may have less direct impact on water use compared to others focused directly on water usage.
-
Offer rebates for people who purchase low-pressure shower heads: Similar to low-flow toilets, this could contribute to reduced water use, especially in residential settings.
Considering the analysis:
- B. Monitor patterns in crop water use to ensure efficient delivery of water.
- C. Offer rebates for people who purchase low-pressure shower heads.
These actions are likely to have the largest impact on reducing total combined water use across states.
