Energy Energy is related to water because there are some hydropower plants near to the city that provides to the city with enough energy. This energy is used to generate light, by industrial and domestic machines. These machines help to improve human production and increase the life quality.

Food Some products like meat and milk travel few hours before coming to the city, but there others like grapes that travel days before coming to the local markets.
