The face of agriculture is dramatically changing in and around cities worldwide. From Anchorage, Alaska to Tokyo, Japan, multi-story indoor farms provide fresh produce, fish and other products to local residents. Some facilities are greenhouses using natural sunlight, others use grow lights. Proponents of these farms argue they use less water and pesticides, while reducing transportation costs and carbon emissions. But critics argue they are not cost effective and consume too much energy. Guest host Maria Hinojosa and a panel of guests discuss the pros and cons of indoor urban farms for this month’s Environmental Outlook.
