Perhaps,my idea on the life in 20 years is quite different from the others.I would like to say that we will have a very miserable life in the 20 years while the other people are dreaming about the future in the same 20 years.It is very clear that we will be living in 2031 in 20 years.And it is very common for most of people to think about the life in an optimistic way.But on the contrary,I insist that we will use up all the natural resources,like oil,coal and gas burried underground.We will have no energy,at least,no such cheap energy like we are using today in 20 years.And the traffic,communication,banking and our daily life will be totally a mess!Sometimes,people would not like to predict the black side of the future until we have to face with it.That will be terrible and dangerous.
