Question

this graph shows the increase in the amount of freshwater that was used worldwide from 1900 to 2000. if the trend that is shown in the graph continues, freshwater resources will be used more quickly than they can be replaced. how might this information best be used to affect decision - making about this global concern? leaders can encourage the use of saltwater instead of freshwater for communities near coastlines. communities can require homes to collect and use rainwater in areas that receive a lot of rain. the information can be widely shared to encourage water conservation in homes and communities. governments can enact laws to restrict access to freshwater.

Explanation:

• Option 1: Using saltwater instead of freshwater for coastal communities is limited in scope and doesn't address the global freshwater - use trend.
• Option 2: Requiring homes to collect rainwater in rainy areas is also a local - scale solution and not a comprehensive way to deal with the global trend.
• Option 3: Widely sharing the information to encourage water conservation in homes and communities can have a broad impact. If more people are aware of the increasing trend of freshwater use and the potential for over - use (faster than replacement), they can change their behavior, which can help address the global concern.
• Option 4: Enacting laws to restrict access to freshwater is too extreme. Freshwater is essential for many basic human needs like drinking, sanitation, and agriculture.

Answer:

The information can be widely shared to encourage water conservation in homes and communities.
