More importantly, research indicates that air transport pollutes the environment. For example, Britain transports half its food by air. However one kilo New Zealand fruit emits five kilo warm house gas on its way to destination. Therefore, some environmental groups and books advocate people to distinguish local fruit and air-transported fruit in an effort to cut the pollution from food 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 and environmental friendly solution should be found to address such problems.
