For some years now the EPA has proposed rules for monitoring and controlling smells from livestock. They say it’s necessary for stopping global warming.
My grandfather had a small farm, typical of the 1930s through early 1960s era. It was in Washington state with a grand view of Mount St. Helens. He had laying hens, pigs, milk cows, a team of draft horses, and raised field crops plus a vegetable garden. By the time I was five years old, I was already well acquainted with farm smells.
Naturally, farm life includes the smells and sights of the great outdoors. Soil, crops, wild flowers, grass, trees, streams, and pure fresh air all have their distinctive aromas and seasonal images. But the animals are the heart of the operation.
