Northern Europeans began using fir Christmas trees before anyone else. The tradition gradually spread across Europe. Despite the eventual introduction of artificial evergreens, America’s Christmas tree farms currently span roughly 1 million acres. Many of today’s holiday trees are spruces, pines or firs.
Evergreens often benefit people who live nearby. During the winter, they can enhance comfort and cut heating expenses by protecting homes from brisk winds. Their thick foliage reduces cooling costs when it shields buildings from bright summer sunlight. They also block and absorb traffic noise throughout the year.
