“One of the least meaningful and most overused words in the English language is 'sustainability.' For most Americans, it means something like 'pretty much the way I live right now, though maybe with a different car.' A good test of any activity or product described as sustainable is to multiply it by 300 million (the approximate current population of the United States) and then by 9 or 10 billion (the expected population of the world by midcentury) and see if it still seems green. This is not an easy test to pass”

“I have said that there is no "average" American. That is due to the circumstance that the people of the United States differ from each as widely as the parts they live in. The New Yorker is a different specimen of man from the Westerner; the latter is entirely different again from the people of Texas. The Middle West, such States for instance as Kansas, Colorado, Nebraska or Iowa, have an entirely different psychology from that of Florida or Lower California. Their habits of life, their modes of thought, even their language is different. Still further, it must also be considered that millions of foreigners and descendants of foreign born people live in the United States and are part of the entire population that is known as "American". Add to this more than 10 million negroes, not to mention the score of different Indian (red-skin) tribes, who are the real, indigenous Americans. In this conglomeration of races it is impossible to speak of the "average" American, nor can any adequate estimate of American psychology be made on such a basis.”

“Indeed, for those in the West inclined to be critical of China, here are few cautionary facts. With its absolutely massive population (1.33 billion or one-fifth of the world's population) it's obvious that China should have a massive impact on the world. Yet, it's one-child policy, for all the uncomfortable ethical questions it raises and the painful sacrifice made by millions of Chinese families, means that China's annual percentage growth rate is low relative to the global average (0.49 per cent versus 1.13 per cent). Even with a population more than four times that of the United States (1.3 billion versus 0.3 billion), China's ecological footprint is still less than that of the US (2456 million global hectares versus 2730 million global hectares). In 2009, China invested far more than any other country in the clean energy industry – $34.6 billion or 0.39 per cent of its gross domestic product compared to United States' $18.6 billion or 0.13 per cent of GDP. When it comes to reforestation, China punches way above its numerical and geographical weight, with massive initiatives like the NFPP and SLCP helping seed some 4 million hectares of forest every year, which is probably more tree planting than the rest of the world put together.”

“Now I have very little respect for the electoral system in the United States. I could have respected it in the early days, when the country was small and we had small population. The system that we have in the United States was set up at a time when the total population was the population of Tennessee. We've stretched it to try to make it work for different kind of problems and in stretching and adapting it, we've lost its meaning. We still have the form but not the meaning. There's a lot of things that we have to look at critically that might have been useful at one time that are no longer useful I think there's some good in everything. There's some bad in everything. But there's so little good in some things that you know for practical purposes they're useless. They're beyond salvation. There's so much good in some things, even though there's bad, that we build on that.”

“Average. It was the worst, most disgusting word in the English language. Nothing meaningful or worthwhile ever came from that word.”

“Thirty million, mostly fools.[When asked the population of England]”
