Chefs A 'Field was one of the first in the cooking genre to focus on environmental issues pertaining to food, travel, and lifestyle. The tradition continues in this fourth season with a strong focus on sustainable agriculture and seafood, shopping with an environmental mindset, ideas to get the whole family closer to where their food comes from, and ways to prepare a delicious meal with healthy ingredients.
