It has allowed life to flourish but it is also the basis of advanced, industrialised societies which are built on the energy of fossil fuels stored in the ground. Plants have developed a form of energy conversion that scientists would love to emulate. Using a pigment, chlorophyll, and a sophisticated bagfull of enzymes called a chloroplast, plants are able to convert the energy of the sun, and the carbon dioxide of the air, into a chemical fuel that can be stored as a fossil fuel for millions of years.

Paul Samuelson: Nobel Prize-winner widely regarded as the most important economist of the 20th century

At precisely eight in the morning of 2 January, 1932, a brilliant first-year student, aged just 16, wandered into a lecture on Thomas Malthus at the University of Chicago – and in his own words, "was born again as an economist."
