“Tremendous economic growth” is expected over the next 40 years, averaging 3.5% per year but much higher in the next 20 years. Despite high savings and investment (currently at >35%), consumption per capita will grow fivefold by 2052. But China’s “footprint on the planet will be substantial,” and climate change will create significant problems of sea level rise and desertification; energy use will more than double by the 2030s; agricultural output will increase by 25% before it peaks in the 2030s and starts to decline.
