Air Survey
The OPAL air survey launched in September 2009 and is coordinated by Imperial College London. The survey asks people to look for lichens on trees and tar spot fungus on sycamore leaves and then record their results online. The survey is helping scientists learn more about the effects of air pollution, and is supported by a number of organisations including the British Lichen Society.

Famous quotes containing the words air and/or survey:
“It is true that the rivers went nosing like swine,
Tugging at banks, until they seemed
Bland belly-sounds in somnolent troughs,
That the air was heavy with the breath of these swine,
The breath of turgid summer, and
Heavy with thunder’s rattapallax....”
—Wallace Stevens (1879–1955)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
