This expansion in Promotion brought about by expanding sand sends out is portrayed on Figure 4. Promotion builds because of the improvement in the exchange balance (trades – imports) and extends and moves to one side from Advertisement to AD2.

Sea shores themselves can likewise be utilized as a wellspring of sand and are incidentally frequently used to construct foundation for the travel industry while obliterating the vacation spot. Extraction of sand from sea shores is generally done illicitly.
