Transport of fruits and vegetables by air enables consumers to enjoy awider variety of fresh and in-season farm products from all over the world. Notonly is air transport good for consumers, it is also a blessing for farmersbecause the market is no longer restricted by regions. As a result, airtransport increases the sale volume by selling more products in more places.

Moreover, air transport of food has now become a major resource of incomesfor air companies. In the past, air companies’ business mainly came from servingpassengers. However, facing an increasingly tough market, air companies need toexpand their share of market to serve a wider range of customers in order tostay in the game and make a profit. With a booming economy and more money tospend, people create a great potential for food transport business and goodmargin for air companies.

In spite of such benefits, air transport is not free of problems. One majorissue is high cost. Air transport is probably the most expensive way oftransport. Higher costs entail high prices, which in turn deprive people withless money the opportunities to enjoy such privileges. So air transported foodis now for the rich, a fact that is unfair for poor people.

In addition, it is not the best option to solve problems by transportingfood from outside for places where certain kinds of fruits does not grow. Themost optimal way, it seems to me, is that we should change the environmentrequired by such plants using scientific and biological methods such as creatingsuitable soil and temperature. Such solutions will be proven to be ultimatelycost-effective and fundamental.

More importantly, research indicates that air transport pollutes theenvironment. For example, Britain transports half its food by air. However onekilo New Zealand fruit emits five kilo warm house gas on its way to destination.Therefore, some environmental groups and books advocate people to distinguishlocal fruit and air-transported fruit in an effort to cut the pollution fromfood consumption.

In conclusion, air transport has many benefits for consumers and farmers,but it also has problems such as high cost and pollution. More effective andenvironmental friendly solution should be found to address such problems.
