Public Impact
A man of strong environmental convictions, he has been described as influential in Britain, although his environmental message has not always travelled as easily abroad, particularly to the United States. His 1977 book 'Climatic Change and World Affairs' argued that mandatory international pollution control would eventually be necessary. Despite his non-scientific background, he is internationally respected as having a strong grasp of science policy issues. He has been the recipient, between 1990 and 2006, of 23 honorary doctorates.
He is currently the president of the UK charity Tree Aid, which enables communities in Africa's drylands to fight poverty and become self-reliant, while improving the environment. He is also a patron of Population Matters, (formerly known as the Optimum Population Trust), and told Radio 4's Today programme that the ideal population for Britain could be around 20 million. As a member of Lord Rogers' Urban Task Force, Tickell counselled against spreading cities saying that we need denser living, that young adults should not expect to leave home straight away, and that older relatives could live in 'granny flats'

Famous quotes containing the words public and/or impact:
“People’s backyards are much more interesting than their front gardens, and houses that back on to railways are public benefactors.”
—Sir John Betjeman (1906–1984)
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
