Define conserve and “Terra”.
Our planet is in trouble! As we know, human population keeps on increasing, our motherearth is getting more crowded and the environment is getting worse because of human irresponsible behaviour and attitude. Recently, our focus is “how to conserve Terra”. It is a good question whether everyone should concern about it? As the old saying says, the environment is our home and it depends on us to protect it. As we get informed by newspaper, Guang Zhou has been dust-haze for a few days and citizens there, had to wear gauze masks in order to protect their breath systems. What leads to this phenomenon? What will happen if we destroy our environment continuously?
1. No plastic Bag
i) Effect of plastic bag to environment and why no plastic bag? * contributes to air pollution and increases energy consumption * takes 1000 years for polythelene bags to break down
* as it breaks down, toxic substances leech into the soil and enter the food chain
ii) How? What should do to reduce the use of plastic bag? * Public should support “No Plastic Bag Day Campaign”. * Use recycle bag (fashionable)

* Decreasing the number of the times that we open and close our refrigerators. * Using air-condition only in essential occasions
* Inform public about the effect of CFC that harm our planet through media. * Government can reduce the use of air conditions in public places * Government may charge their people more than now on electricity bills to discourage them from being carless and carefree about this subject.
