A tree autobiography can be read through its growth rings, which serve as a record of its life history. Each year, a tree adds a new ring composed of both light and dark layers. These rings reveal valuable information about the tree's age, health, and environmental conditions it endured. The width of a ring can indicate periods of growth and stress, such as droughts or disease. Moreover, scientists can analyze tree rings for insights into past climates, as the rings may vary based on temperature and rainfall. In essence, a tree's autobiography is a silent, enduring testimony to its experiences and the world's changes around it.
