Concept:Environmental control measures are actions taken to protect, conserve, or maintain the environment from further damage.
Explanation:Preservation is a control measure because it protects natural resources from harm.
Stabilization is a control measure because it prevents soil erosion and land degradation.
Afforestation is a control measure because it involves planting trees to reduce desertification and erosion.
Degradation, on the other hand, refers to the process of the environment becoming damaged, depleted, or destroyed.
Therefore, degradation is not a measure of environmental control, but rather a condition or process that control measures aim to prevent.
Answer:Degradation (Option C) is not a measure of environmental control.
