Vaclav Smil

"Vaclav Smil's mission is to make facts matter. An environmental scientist, policy analyst, and a hugely prolific author, he is Bill Gates' go-to guy for making sense of our world.

The book begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying...

Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows -- ranging from fossil fuels to photovoltaic generation of electricity -- for their civilized existence....

"The modern world was created through the combination and complex interactions of five grand transitions. First, the demographic transition changed the total numbers, dynamics, structure, and residential pattern of populations. The agricultural and dietary transition led to the emergence of highly productive cropping and animal husbandry (subsidized by fossil energies and electricity), which eliminated famines, reduced malnutrition, and improved the...
