1st Exchange Session
Summary: 
1) The problem(e.g. causes, consequences) of climate change in Hong Kong, Atlanta and Xian) 
(a) Identify the common ones and unique one;
Common One: 
	We all believe that human activities cause an increase in the atmospheric concentration of greenhouse gases including the most common one is carbon dioxide. (Causes)
	We all think that the consequences of climate change are constituting the increase of hot days and decreasing of cold days. Moreover, we all agree that climate change will intensify the global warming effect which will rise global temperature, leading to the shortage of summer. Additionally, we all believe that the problem of pollution has been alleviated. Under the influence of COVID-19, many human activities stopped which provide an environment with some buffer to repair its damages. (Consequence)
Unique One: 
	In Atlanta, people's awareness of saving energy is relatively low. Therefore, they prefer to turn on the air-conditioner in spring or summer rather than turn on a fan. In their perspectives, they are seldom concerned about an environmental problem, thus they are not going to make any changes in their daily habits (Causes)
Unique One: N/A (Consequence)
(b) Discuss the potential/perceived problems in Xian/China
	The burning of coal is the main reason for intensifying the global warming effect, leading to the deterioration of air pollution and rising temperature in China.
Reflection
	It is the first time to meet my groupmates through zoom, I am quite nervous and excited to chat with them. Although I feel a little bit shy and embarrassing, they are enthusiastic and active in presenting their idea and listening to my viewpoints. I do think that it is a great chance for me to broaden my horizon and get in touch with different people which not only can it help to enrich my learning experience but also useful to facilitate cultural exchanges between Atlanta and Hong Kong. I am looking forward to seeing them in the next session, I hope that I can be braver to express my view and we can get more familiar with each other too.
