Therefore, nutrient loss will be higher in clear- cut watershed than natural forest watershed.
Ozone is good when it is in the stratosphere but bad when in the troposphere (where the weather system occurs). When in the stratosphere it help absorbs UV light from sunlight before reaching earth surface. This prevents damage to the genetic material of living organisms.
When in the troposphere, it is considered a pollutant and causes irritation of the lungs when inhaled. It also affects vegetation by reducing crop growth and yield.
