The local food movement continues to grow in popularity as people become more health conscious and attuned to where their food is originating. If you have a desire to grow your own food or lessen your environmental impact by purchasing locally grown produce, eggs and meat, the Gwinnett Environmental and Heritage Center is hosting its third annual Grow Your Own — The Real Local Food Festival from 1-5 p.m. Sunday, March 30. The festival will include four speaker sessions conducted by local farmers and community gardeners.
