Bike sharing, a charity auction for ballet, and SustainaVille

For those who want to celebrate Earth Day all spring long, the Cape Ann Museum in Gloucester is the place to be. Artist Esther Pullman spotlights her work in a panoramic photography exhibit that features greenhouses, nurseries, and other places in which plants are grown. Each piece features at least two photos to create the panoramic effect. The exhibition runs until June 16. The Cape Ann Museum is at 27 Pleasant St. Museum information can be found at 978-283-0455, ext. 10, or www.capeannmuseum.org.

Somerville will transform into SustainaVille for the third year. From Saturday, April 27, through May 4 the city holds events dedicated to educating residents about the environment and “Going Green.” There will be a class on urban gardening, Earth Day storytelling, and a self-guided citywide sustainability tour. The events vary in prices and location, so interested participants should check out the full schedule. Registration is recommended, but not required. Somerville Mayor Joseph A. Curtatone said: “My hope is that SustainaVille week will encourage us all to get the facts about our environment and what we can do to make a positive impact on it.”
