WSJ: "The World's Resources Aren't Running Out"

Matt Ridley column in WSJ. Some good points.

"[W]e would have bumped our heads against all sorts of ceilings by now, running short of various metals, fuels, minerals and space. Why did it not happen? In a word, technology: better mining techniques, more frugal use of materials, and if scarcity causes price increases, substitution by cheaper material. We use 100 times thinner gold plating on computer connectors than we did 40 years ago. The steel content of cars and buildings keeps on falling."

It's still a finite world, but technology can solve many problems.
