Fernwood Botanical Garden and Nature Preserve in Niles is teaming up with Chikaming Open Lands for an environmental film festival this summer. Fernwood tells us they’ll be showing two films with a green message. First up will be “One Big Home,” to be presented July 24 at the Vickers Theatre in Three Oaks. Twelve years in the making, One Big Home follows one carpenter’s journey to understand the trend toward giant houses on the tiny island of Martha’s Vineyard. The next film to be screened will be “Landscape Film: Roberto Burle Marx,” to be presented at the Vickers Theatre on August 14. It’s a journey through the art and life of the Brazilian landscape architect and painter Roberto Burle Marx. Those who want to take part in the film fest can call Fernwood Botanical Garden to register.
