Final answer:
Creating buffer zones near a coastal town to address sea level rise is the most closely associated action with sustainable protection of natural resources.
Step-by-step explanation:
The action most closely associated with sustainable protection of natural resources is creating buffer zones near a coastal town to address sea level rise.
This action involves setting aside areas near coastline to allow for natural ecosystem preservation, which helps protect against the impacts of sea level rise. These buffer zones can reduce the risks of coastal flooding, provide habitat for coastal species, and maintain water quality.
Other actions mentioned, such as farmers practicing erosion control, a city voting to increase mass transit options, and making family planning resources more freely available, may contribute to sustainability and conservation efforts, but they are not as directly linked to protecting natural resources in the same way as creating buffer zones near coastal areas.
