雅思大作文范文：
The food travel debate is inevitably intertwined between economic interests and environmentalconcerns. While food is traveling because transport has become so cheap in a world ofglobalization, the manner by which food is being carried is not doing the natural environmentany favors. The question is whether to meet human food demand or to reduce pollution?
Linking food with transportation is big business. The ability to transport food cheaply hasgiven rise to booming business regarding freight by land, sea and air. As the populationcontinues to grow, so does the demand for food. Nowadays, all kinds of food may be carriedlong distances from producing regions to consumer markets in a matter of weeks, days or evenhours. Such is a win-win trade practice, benefitting both sellers who can help create morevaluable jobs and buyers who can help supply consumers with more food varieties at moreaffordable prices. At this point, commercial globalization seems to be positive at its best,justifying in part why foods need to travel thousands of miles.
Of course, the negative side is about pollution. Despite the fact that buying and selling foodsbeyond borders may bolster economic relationships, the environmental impact oftransportation is just too great to ignore. Big trucks, huge ships and giant airplanes that areused to carry foods use fossil fuels. Fuel burning has become so excessive thatenvironmentalists behind a green cloak are calling on policy makers to effectively reducepollution, or else. The warning is certainly not groundless, considering that pollution fromtransportation accounts for no small a part of those emissions which are believed to generategreenhouse effects that eventually cause the Earth's climate to change. Obviously, the longerthe distance food travels, the fuel consumption of the transportation vessels will also begreater, and no doubt the more serious the global warming.
In view of both the positive side and negative side about long-distance food transportation,there seems no easy answer to the question. Nevertheless, it is up to consumers to makechoices, knowing where food comes from. Buying local produce not only supports local farmersbut also provides dinner tables with the freshest and most nutrient-packed options.
