Consequently, most of the worlds fridges are to be found, not in the tropics where they might prove useful, but in the wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house-while outside, nature provides the desired temperature free of charge.
The fridges effect upon the environment has been evident, while its contribution to human happiness has been insignificant. If you dont believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers(汉堡包), but at least youll get rid of that terrible hum.
