It is not difficult to see how polluted the air is in the region. Take a glance at Victoria Harbour to recognise how serious the problem is. Therefore, action must be taken to reduce pollution levels.
As individuals we can all do our bit to be eco-friendly. When it comes to schools, they should be aiming to use renewable energy sources. Renewable-energy-source technology has improved a lot over the years. It is now relatively easy to install solar panels and windmills. This benefits society as a whole, with less electricity being consumed and has an educational role for students. I can appreciate that there may be drawbacks. Cost-efficiency may be a factor that has to be considered.
Also, building plants used to operate wind turbines and solar panels would restrict the limited space for teaching. However, I am sure there will be some technological breakthrough that will solve this problem.
