The staff of The Heritage Project explained each exhibit and it was a great way to learn about Hong Kong's history. I learned about the Kadoorie family and the Japanese occupation of Hong Kong during the second world war. I also discovered that the 1881 Heritage building was a former Marine Police headquarters. What's more, I read an old book which offered valuable information on Hong Kong's past.

The Peninsula was our first major topic. During the Great Depression, the British held an industrial fair there similar to the World Fair in Chicago in 1893, but it only had British goods. At the time, Hong Kong was a British colony.

Many Jews went through Hong Kong to get to their desired destinations after the second world war. One time, The Peninsula housed 300 Jews who were stranded in the city after the Australian ship that was supposed to take them was used to ferry troops.

We also learned the Cross-Harbour Tunnel was first proposed in 1902 to ease traffic congestion but was not built until 1972.

1881 Heritage, a former Marine Police headquarters, is one of the most beautiful complexes I've ever seen. I've always loved hotels, and during my visit, I learned about the history of two of my favourite hotels: Sheraton and The Peninsula.

Before the Sheraton was built in 1973, the vacant land at the junction of Nathan Road and Salisbury Road was a prime trade-fair site.

The Peninsula had served as the headquarters for the Japanese military during its occupation of the city and as the British administration headquarters in the immediate post-war months.

Go green - the 3 Cs

Following last year's success, green group WWF is extending its Climateers Ambassador Experiential Programme to the Sai Kung and Wan Chai districts.

The programme, organised with support from the Environmental Protection Department, shows how individuals can make a difference in reducing Hong Kong's global carbon footprint.

Two junior reporters have signed up to become ambassadors and will report their experience in Young Post. Elaine Yu, from Sai Kung district, went to the opening ceremony last Saturday. Here is her report.

We can drastically improve our environment if we are willing to take some simple steps.

Last Saturday, the opening ceremony of the Climateers Ambassador Experiential Programme brought together many concerned residents from Sai Kung and Wan Chai.

WWF invited some guests, including environmental expert Lowell Lo, celebrity chef Margaret Xu, and head of the climate programme at WWF Hong Kong, Dr William Yu.

They shared their opinions on how to tackle climate change and ways to lower our carbon footprints.

Some Climateers Ambassadors will visit the Mai Po wetland this weekend to learn more about the fight against global warming.

But for now, here's something you should know: the 3Cs - calculate, cut and communicate.

First, calculate your carbon footprint. Second, cut wastage and set a goal to reduce your carbon footprint. Last but not least, communicate with people and encourage them to adopt a low-carbon lifestyle.

You may not be a WWF Climateers Ambassador, but you can read our reports and help reduce the effects of global warming. Start by implementing the 3Cs.
