Interview with Vaclav Smil

I haven't read any of his books, Harvesting the Biosphere: What We Have Taken from Nature is next on my reading list. Interview here:

Your interests are incredibly broad-sweeping. What is your educational background, exactly?

I’m the product of the classical, old-fashioned European education that is broad-based. You want to get your degree in the world, you have to study all sorts of things. I studied what the Germans call the Naturwissenschaften, the natural sciences. Everything from biology to geology. How the clouds are formed, how the animals live, and what makes the rocks. So I know about nature. Period.

I’ve read about 80 books a year for the past 50 years. I come from cultural breeding. I don’t have a cellphone.
When you spend all your time checking your cellphone messages, or updating your Facebook (of course I don’t have a Facebook page) then you don’t have any time for reading.

What was the key lesson you learned while writing Harvesting the Biosphere?

Harvesting the biosphere is still the most fundamental human activity. Without that, everybody’s dead, really. We could do quite well without microchips, or the business site of Atlantic Monthly, the gated communities, Guccis, and high growth GDP. But we cannot do without harvesting the crops and cutting down the wood. No human civilization could ever sever our dependence on photosynthesis.

People are obsessed with the progress of electronics and high speed machinery and things like that, but first things first. If you ask “what has been the most important invention of the past 100, 150 years?” it’s been the synthesis of ammonia. If we could not synthesize ammonia by taking nitrogen from the air, hydrogen from natural gas and pressing them together in the Haber-Bosch cycle… if we could not do this to make nitrogen fertilizers, we could not grow enough food for about 40% of people. So you are talking about something like three billion people. In existential terms, that is the most important invention.
