"In our society, high taxes on labor drive businesses to minimize the number of employees. Resources remain untaxed, so we use them unconstrained. This system causes both unemployment and scarcity of resources." Read. Via Femke Groothuis.
Minerals Yearbook: an annual publication that reviews the mineral and material industries
of the United States and foreign countries. The Yearbook contains
statistical data on materials and minerals and includes information on
economic and technical trends and development. The Minerals Yearbook
includes chapters on approximately 90 commodities and over 175 countries.
Following the intriguing but oversimplified graphic on materials scarcity published by New Scientist (a graphic that turns out to be 2 years old, by the way), this in-depth article at the Oil Drum Europe (original article here)
gives a well founded look at the problem of metal minerals scarcity.
Especially interesting is the link between energy and minerals:
"In case of unlimited energy supply, metal
minerals extraction would only be limited by the total amount of
mineral resources. However, due to the scarcity of energy, the
extraction rates of most types of metal minerals will cease to follow
demand. Probably the only acceptable long-term solution to avoid a
global systemic collapse of industrial society, caused by these
resource constraints, is a path towards managed austerity. Managed
austerity will have to be a combination of changes in technology and
changes in both individual and collective human behaviour."
