Local author Ali Berlow, editor of “Edible Vineyard,” the local magazine that focuses on the food that is grown, caught, cooked, and eaten on the Vineyard, and founder of Island Grown Initiative, a grassroots nonprofit that works to grow community through sustainable agriculture, local food advocacy, and education, knows a thing or two about being smart and sustainable with your food.

Ms. Berlow recently wrote a new book, “The Food Activist Handbook: Big and Small Things You Can Do to Provide Fresh, Healthy Food for Your Community,” that provides helpful ways you can take more ownership of the food you consume. She’ll be speaking on the subject on Wednesday at the Chilmark Public Library.

“Small steps can create big changes in your community’s food quality and food security, helping to get more healthy food to more people and support a better food system,” says Storey Publishing. “Ms. Berlow shows you dozens of things that anyone can do, from creating a neighborhood kitchen for preserving fresh food to mapping farmland, connecting food pantries with food producers, starting a school garden, and organizing a community composting initiative. Every action you take can help keep farmers on the land and family farms intact, keep money in the local economy, reduce the carbon footprint associated with food transportation, and preserve local landscapes. If you’ve had enough of E. coli scares, disappearing farmland, pesticide problems, and hunger in your community, this inspiring book will show you exactly how one person really can make a difference.”

Ms. Berlow is also the author of “The Mobile Poultry Slaughterhouse.”

Ali Berlow, at the Chilmark Public Library, Wednesday July 22, 5 pm. Admission is free. The program is sponsored by the Friends of the Chilmark Public Library. For more information, please call 508-645-3360.
