I would respond to the local Green group's questions about environmental issues in Hong Kong in the following way:
The article discusses how people tend to produce more household waste during the Christmas period than any other time of year. It found that waste includes shopping bags, leftover food, wrapping paper, gift packaging, as well as disposable tableware. Additionally, increased electricity usage and travel have further negative environmental impacts during this season.
However, small changes like reusing materials for wrapping gifts or decorations, having candlelit dinners, and reducing overall consumption can help lessen environmental effects. Educating others about more sustainable practices during the holidays is important.
