Which human action disturbs vegetation balance?

Correct answer: Reckless deforestation

The direct answer is A: reckless deforestation. Vegetation balance means a reasonable relationship among plants, soil, water, animals, and human use. Step by step: trees are cut faster than they can naturally regrow; forest cover decreases; habitats are destroyed; biodiversity falls; roots no longer hold soil as effectively; erosion, runoff, and loss of moisture can increase. Reckless cutting may also disturb the carbon cycle and local climate. Option A is correct because it is a clearly harmful human activity. Option B, creating protected areas, normally supports vegetation by limiting damaging use and protecting habitats. Option C, planting trees, can restore cover when done suitably with appropriate species and care. Option D, conserving forests, directly protects vegetation balance. These positive actions can have management challenges, but they are not the harmful action asked for. In an MCQ, words such as “reckless,” “uncontrolled,” or “excessive” usually signal environmental degradation. Memory cue: cutting without replacement means less forest, less habitat, and more erosion.
