TWO groups of students who ran eco-friendly restaurants helped promote the conservation message and learned about the importance of maintaining a healthy environment. Twelve students from Tsang Pik Shan Secondary School were divided into two groups to set up eateries for the television show Challenge of Life II, produced by Radio Television Hong Kong. The programme aims to raise environmental awareness among teenagers through a series of competitions and field visits. Tsang Pik Shan students joined the activity on environmentally-friendly restaurants. They showed the audience how to run a restaurant using materials that would not damage the environment. They were careful about their cooking methods, the materials they used to decorate the restaurants and how they disposed of the rubbish. The two groups - red and yellow - comprising Form One to Form Three students, were asked to set up eateries in Shamshuipo. The judges evaluated their restaurants' decor, how they cooked the food and packed them and the response of their customers - 40 Form One students from their school. The students had to follow green guidelines adopted by the programme producers and also make their restaurants appealing to the customers. For example, the yellow group opted for the simple look - they used just one colour to paint their restaurant. Also, they served fried rice in a coconut shell. But they made a serious mistake. They put their takeaways in polysterene boxes which could not be recycled. The red group showed their creativity in decorating the restaurant. The students used sand and seashells they collected from the beach to give their eatery a unique look. And they chose reusable plastic boxes for takeaways. The students said the boxes were expensive and users would not throw them away, so there was no threat to the environment. Although they put a lot of effort into reducing wastage and ensuring a healthy environment, the two groups found out that most customers were only concerned about their food. The programme will be broadcast at 7pm on September 6 on Jade.
