Dear Phuong,
I received your email the other day and you asked me about my Vietnamese city. I've thought about it a lot, and now I can give you two predictions.
Take an optimistic view. In 2076, Vietnam will become a more livable center than ever before for many reasons. The city government has a very careful plan to promote self-driving electric taxis to cope with crowded public transport. In addition, city residents are encouraged to use city rooftops for gardens that are fertilized with compost to recycle trash and reduce pollution.
On the other hand, the pessimists think that city life will not be a safe place to live because the government cannot control the use of guns, and hence the crime rate; will be higher. People's lives will also continue to be threatened because of natural disasters such as floods, storms, and earthquakes. The impact of global warming has an impact: the impact on city dwellers.
These are the things that I want to tell you. I hope you will be satisfied with it, phuong
Love you,

Linh
