　　The Horn of Plenty is one of the largest natural health food stores within the Greater Hamilton area．We are big supporters of buying locally and we are here to tell you why it is so important for your family，the community and the environment．The concept of buying locally is simple：buy food produced，grown，or raised as close to your home as possible．Not only will your food be fresher and tastier，but you are helping protect the environment and are supporting businesses within your community and reducing pollution．

　　Better for the environment

　　Sustainabilityand global warming are such hot topics at the moment，and many people want to do their bit to help support a healthier environment．Small action carried out by many people can make a big difference．Most materials in an average North American meal have traveled about 1，500 miles to get from farm to plate．To cut out a big part of this travel would greatly reduce not only pollution from transportation and refrigeration but also customers'expenses as well．

　　Taste and nutritional content

　　Locally-grown fruits and vegetables are usually sold within 24 hours of being harvested．Because they are picked at the height of ripeness（成熟） and travel only a short distance to the market，their freshness，nutrition，and flavor are kept．Produce trucked in from far away may lose both taste and nutritional content．Community and home values

　　When you buy direct from a farmer or buy locally-grown foods，you are engaged in a time-honored tradition between a grower and an eater．You also help keep dollars within your community．
