"Earth Citizen Programme - Eco Week" is going to be held in our school, so that students and teachers will be given chance to discuss environmental issues and develop environmental friendly habits. "Eco Week" consists of five topics relating to environmental protection to introduce us a better understanding of the subject and practice in daily life. And the five themes of "Eco Week" are: Low Carbon Day, Vegetarian Day, Energy Saving Day, Recycling Day and Water Saving Day. We invite a speaker, Mr. Law from Greeners Action and he provides us with a talk to learn more about the relationship between carbon emissions and us. Students from S.1 to S.5 have joined the talk and it lasts for two hours.
