Genuine Used Cars is a second-hand car dealer with a landscaped yard on a busy highway serving Sydney. The plants used to 'decorate' the yard are all high water users. Drought is setting in and the local council has asked businesses to conserve as much water as possible. Town water is still available, bore water may be accessed in fairly shallow bores and the council is encouraging businesses to install underground tanks to conserve rain water. Which source of water should be used to gain the most brownie- points ethically? Should the firm change the plants for more efficient water users?
