Storing our foods and keeping it fresh requires a fridge to do it. Normally, refrigerators are one of the big contributors to green house gases. That is why people in Nigeria have created a simple device called the Zeer. Zeer is a gadget used for storing and cooling off foods, a truly simple yet effective method in preserving the freshness of our foods. With the use of natural resources like earthenware pots, sand and water, the Zeer can now be able to preserve the freshness and eventually refrigerate your foods. This is truly a great way of preserving energy consumption, since refrigerators eat up large amount of energy in every household.
