A tree is a perennial woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance. A minimum height specification at maturity is cited by some authors, varying from 3 m to 6 m; some authors set a minimum of 10 cm trunk diameter (30 cm girth). Woody plants that do not meet these definitions by having multiple stems and/or small size are called shrubs. Compared with most other plants, trees are long-lived, some reaching several thousand years old and growing to up to 115 m (379 ft) high.
Trees are an important component of the natural landscape because of their prevention of erosion and the provision of a weather-sheltered ecosystem in and under their foliage. They also play an important role in producing oxygen and reducing carbon dioxide in the atmosphere, as well as moderating ground temperatures. They are also elements in landscaping and agriculture, both for their aesthetic appeal and their orchard crops (such as apples). Wood from trees is a building material, as well as a primary energy source in many developing countries. Trees also play a role in many of the world's mythologies (see trees in mythology).

The Christmas tree, also known as a Yule tree, is a decorated evergreen coniferous tree, real or artificial, and a tradition associated with the celebration of Christmas. The tradition of decorating an evergreen tree at Christmas started in Livonia and Germany in the 16th century. The Christmas tree is traditionally brought into the home and decorated with Christmas lights (originally candles), ornaments, garlands, tinsel, and candy canes during the days around Christmas. An angel or star is placed at the top of the tree, representing the host of angels or the Star of Bethlehem from the Nativity.

John Krubsack (1858-1941) was a banker and naturalist from Embarrass, Wisconsin. He conceived, planted and shaped living trees to create the first known grown chair. He started his chair in 1903 and harvested 11 years later in 1914.
In addition to banking, Krubsack was a prominent naturalist who farmed, made cheese, and landscaped his property long before these were common practice.[clarification needed] His house was the first in his region to have running water. He also was skilled at piecing together furniture from found branches. He’d scour the local river flats with a yardstick and a saw, looking for just the right shaped piece of blue beech, a hardwood tree with a smooth, wavy bark and a beautiful blue color when varnished. John took his youngest son, Hugo, on these weekend wood-hunting excursions, and it was during one of his trips that the idea first came to him to grow his own chair. Read more...
