Firstly, I think we should change our mindset. I am not sure what westerners think about environmental protection. But I think many of the Hong Kong citizens ( adults ) have no idea about it. Every time I suggest not using plastic drinking straws or cutting down on the use of air conditioning in the winter, people don't take me seriously.

Firstly, I think we should change our mindset. I am not sure what people from western countries think about environmental protection, but I think many people of Hong Kong ( adults ) have no idea about it. Everytime when I suggest no drinking straws or turn off the air conditioning in the winter, they are sarcastic to it. For us, supermarkets are not allowed to sell party plastic plates, cups, forks, spoons and straws anymore. It is also quite common now to bring our own reusable shopping bags when we shop for groceries at the supermarket so we don't take any new single use plastic bags every time we shop.  There are some documentaries on TV that help highlight the problem so people here are a little more aware and open to changes. But there is still a LOT more that can be done.  Like you, my wife and I also don't take any straws when we eat out, we just drink straight from the cup. But I can see other customers around us still using straws so some restaurants here still supply them unfortunately. :(
