FROM THIS EPISODE

On this 40th anniversary of Earth Day, we look at efforts to make Los Angeles' environment more livable. We'll see how Tree People has gone national but stayed local, how a measure of what's called "environmental justice" has been achieved and what's being done to power down to prepare for the end of the age of oil. On our rebroadcast of today's To the Point, this week's volcanic eruption is a wake-up call for the airline industry and unprepared regulators.  It's also a lesson in humanity's inability to control nature.  How likely are bigger eruptions? Is there any way to get ready?

Main Topic Are We Prepared for Volcanic Disruption? 27 MIN, 59 SEC

Air travel in Europe is almost back to normal, although shifting winds have sent plumes of volcanic ash over Scotland and Scandinavia, forcing some airports to close again. Even as Iceland's volcano calms down, damages from this week's eruption continue to mount and so do complaints about the way it's been handled. We hear about volcanoes -- past, present and future -- and learn how to prepare  for volcanic disruptions.

Guests:
Steve Lott, Head of Corporate Communications, International Air Transport Association
John Ewert, Volcanologist, US Geological Survey
Einar Kjartansson, Geophysicist, Icelandic Meteorological Office
Simon Winchester, author, 'A Crack at the Edge of the World'

Main Topic Greening LA: Status Report on the 40th Anniversary of Earth Day 25 MIN, 45 SEC

Acid rain was reduced by new federal regulations on sulfur emissions; the EPA got the lead out of gasoline; it took an international treaty to protect the Ozone layer. But a lot of environmental progress has been made on the local level. Then 15 years old, Andy Lipkis started the Tree People three months after the first Earth Day 40 years ago.  We speak with Lipkis and others about local efforts at protecting the environment and the quality of life in Southern California.
