We know almost half the world is urban(都市的) now – but what will our world look like in the year 2100?

It took about a million years for the global human population to come up to 1 billion in 1800. In the next 200 years it came up to 6 billion and it will take only about 20 more years to add another billion. By 2100 the United Nations estimates that the global population will attain more than 10 billion.

By the end of 2008 slightly less than 50 percent of the global population lived in cities. If economic development proceeds at today’s pace over the next century or so it is highly likely that 8 billion people will live in urban centers up from today’s roughly 3.3 billion. Yes the world will indeed be able to hold so many people. The major reason is urbanization(城市化). There will be many more new cities in the year 2100 and some of today’s large cities will become super cities including Beijing Delhi Mumbai Sao Paulo Shanghai and so on. At the same time recent advances in agriculture energy and water technologies suggest that human creations will keep up with population growth. Rural areas will return to an agrarian (农业的)centre to feed the growing cities. Languages will drop from the current 7 000 across the globe to less than a few hundred. English will be the primary language of the world.

As we compress(压缩) people into the urban center and as we leave behind the rural areas to feed us – will we really live a happy life at that time? We will have to live together in large buildings in cities and save on energy and services delivery cost. There will be few chances for us to get close to nature. We really need to think about the effect of the things we have done and are doing now!
