Earthwise is presented by Lois and Martin Griffiths.
Every programme features a discussion on a topic to do with conservation, environment or peace with justice. Sometimes the interview is with a local Cantabrian, sometimes with someone in a different part of the country, sometimes with a visitor from overseas.
The choice of topics varies considerably. Earthwise hopes that people who are especially interested in conservation will also find peace with justice issues interesting and vice versa. Every programme is promoted on several email lists: Forest and Bird, Green Party, CAFCA and other peace groups, depending on the feature topic.
Every programme also includes community announcements and discussion about other issues, depending on the available time.On every Monday at 9pm, with a repeat on Wednesday at 9pm.
