Correct Response: D. Purchasing locally grown food and locally produced household items benefits the local economy by supporting small businesses, which then reinvest their profits in the region. Advocates of these purchasing decisions also note that "buying local" benefits the environment by preserving green space in the community. Shopping at a local retail business has the potential to help a small business grow economically, but substituting generic for brand-name products (A) will likely have little impact on either the local economy or the environment. Donating items to local charities (B) benefits the environment by reducing waste in landfills but does little to spur economic growth. Individual composting of household food wastes (C) benefits the environment as well, but the derived economic benefit is solely on a personal level.
