 have a consensus that is the need to address environmental unsustainability and the resource constraints through a paradigm shift from an industrial to ecological civilization. In an agrarian society the sky is always blue and water is clean but the quality of living is pretty low. The solution to underdevelopment you may agree with me is industrialize and urbanize. And China is now halfway through the transition from an agrarian to industrial society in less than 40 years. Poverty has been substantially reduced if not eliminated. More than more people living in cities than in rural areas and of course income has increased from low to medium level. But this is at a price in particular with respect to environmental sustainability and the resource constraints. Urban diseases are very widespread and alarming like air pollution, water shortage and contamination, food insecurity, food unsafety and of course traffic jams and heavy reliance on inputs of raw materials from outside. The scale and the challenge of urbanization in China is unprecedented in the history of human development. In 2030 or so we would have over 1 billion Chinese living in cities. Now what are we going to do? Can we continue such a path of development? We need to rethink the current pattern of development. The current way of development of course is something we call an industrial way of industrial civilization which relies on eutoniterian and fossil fuels. Eutoniterian you know if there's a utility and then there would be a value. There's no profit maximization pays little attention to the negative external effects. So in this case the fossil fuels are exhaustible. Then the fossil fuels are depleted and then how are we going to continue our industrial civilization. So this proves that we need to have a new paradigm for harmony between man and nature. And this is something we call in contrast to industrial civilization, ecological civilization. Under such a new paradigm the ecological system will be resilient with a high level of natural productivity. The economic system will be characterized by low input, zero emission and high output. And the institutions will be well designed and functioning for prosperity and sustainability. Then we need to see what are going to do in the future. The Chinese government is very aware of the challenges in terms of global sustainability concern in particular climate change. Current emission in China in per capita terms we are higher than quite a few EU member states like France and Sweden. In aggregate terms the total amount is the combination of the United States and the EU 27. So we have to change the paradigm. Through such a change of paradigm we can remove the roots of unsustainability. And what we have would be the increased appreciating natural assets instead of some sorts of unnecessary, excessive depreciating artificial assets. Thank you for your attention. Thank you. Thank you very much.
