Volcanoes around the World; Earth Day in Los Angeles

Hosted by

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?
