元朗到中環 36 km
元朗到大埔 30 km
元朗到鰂魚涌 45 km
The Impact of Long Distance Food Materials Transportation on Air Pollution
The real environmental cost of purchasing imported produce is not only influenced by the transportation process of these produces. Other factors such as industrialized farming, food processing, and storage are also key in contributing to the overall environmental cost. As fossil fuels are burned to turn into energy to power all these processes, the result is detrimental on the environment. Here are few examples
Example 1 Grapes
The aerial transportation of a bunch of 200 gram Chilean grapes to Hong Kong will generate one and a half kilograms of greenhouse gas.
Example 2 Kale
The distance it takes to transport Kale from US to HK is 13,000 km by air, while locally grown organic Kale sold at local farmers' markets travels no more than 100 miles, for example:
Yuen Long to TaiPo 30km
Yuen Long to Central 36km
Yuen Long to Quarry Bay 45km
Each time you purchase a local grown produce, such as Kale, you can help reduce 360 times of unnecessary food miles!
• 維他命 B、C及E是對抗自由基，預防疾病如心臟病、癌症的重要抗氧化物，而進口新鮮食材比本地即日收割食材，較有機會流失更多養份
• 菠菜於收割後24小時內，若存放於室溫，維他命 C會慢慢流失 50-90%
Loss of Food Nutrition & Freshness
Loss of nutrition & freshness may incur during the delivery process of imported produce. For instance:
• Vitamin C, B and E are all important antioxidants that protect our body against free radical damages that are the root cause of common diseases such as cancer. Imported produces have lower levels of these vital vitamins compared to freshly picked fruit and vegetables that have retained the maximum amount of nutrients before reaching the consumers.
• Spinach stored at room temperature loses between 50 and 90 per cent of its vitamin C within 24 hours of being picked.
• Folic acid, present in many green leafy vegetables, is prone to deterioration with time and exposure to light.
There are a wide range of local produces readily available at our finger tips. Hong Kong has produced many of the common food items that we regularly find on our plates, such as vegetables, chicken, pork, condiments, and seafood. “Eat the Seasons” isn’t just a slogan; it best describes the local farming practice where farmers would only grow crops best suited for the local climate.
