Answer:
The first and best defense against plant diseases is a healthy plant, which is the main task of an accomplished gardener. Preventing and managing plant disease begins even before planting, with site preparation and plant selection.
When a plant does not look normal, or as expected, a gardener may assume that the plant is diseased and control measures are needed. To properly diagnose plant problems, the gardener needs to have background knowledge about the plant, the current environment, and the typical diseases or other problems to which the plant is susceptible. Such information can help prevent an inaccurate diagnosis that may lead to unnecessary pesticide use, wasted time and expense, and continued plant decline.
This publication provides gardeners with information on how to establish and maintain healthy plants, and describes a systematic approach to identifying and solving problems that do occur.

COPD, or Chronic Obstructive Pulmonary Disease, pretty much says it all. In COPD the Bronchioles (the pathways of air to the Aveoli), become inflamed and are occluded by mucus, because the Cilia which are responsible for pushing it out of the tract have been damaged. Because of the narrowing, the Aveoli attempt to increase the surface area so that more oxygen can be absorbed by the lungs, however this can lead to a problem as the dead space (space that is not the aveoli and can be absorbed) is then expanded as well, which leads to shortness of breath.
