Food production on the mainland is under threat because of contamination. Supermarkets sell so-called green food and organic vegetables but some people think the products may not be very healthy.
A recent survey revealed that 24 per cent of organic vegetables are uncertified. The Hong Kong government should co-operate with Beijing authorities to regulate the food industry.
Hong Kong's food supply is highly dependent on the mainland. Almost half of the organic vegetables come from across the border. Officials should check the farms frequently and make sure they do not use any chemicals.
The Hong Kong government should introduce a licence system for farmers to ensure the quality of organic food and protect consumers.
It should also educate the public about the advantages of eating organic food. This will boost consumer confidence and help people lead a healthy lifestyle.
