Blight refers to a condition that causes plants to deteriorate or die, often due to disease, pests, or environmental stress. It can affect crops, gardens, and natural vegetation, leading to reduced yields and economic losses for farmers. Common types of blight include potato blight, which is caused by a fungus, and fire blight, which affects fruit trees. In addition to plants, the term "blight" can also describe urban decay, where areas become rundown and neglected. This can result from economic decline, population loss, or lack of investment, leading to abandoned buildings and decreased quality of life for residents.
