As a matter of facts, many consumers only have vague ideas of what food products they might consume over the next few days. As a result, they are easily tempted to impulsively buy foodstuffs that are of littile use to them. Second, the unregulated cultivation of many different crops in many countries might surpass the demand for food of their citizens, which gradually results in an increase in the amount of superlflous food. For example, food wastage in Vietnam has become excessively prevalent in recent years because a great deal of fruit and vegetables such as watermelons or pineapples is cultivated and collected uncontrolably
