The desert setting is described as a fragile environment. What does this imply about the impact of waste disposal in such regions?

• A. It is especially sensitive to improper waste disposal
• B. It is resilient to waste disposal
• C. It benefits from waste disposal
• D. It is unaffected by waste disposal

Answer: (A)

Fragile environments have a limited capacity to absorb disturbances, and deserts accentuate this because water is scarce, soils are thin, and life is highly specialized. When waste is disposed of improperly, pollutants don’t get easily diluted or broken down—leachates, chemicals, and plastics can persist where rainfall is infrequent and evaporation concentrates contaminants. This can contaminate soil and any existing groundwater, harm plants and animals already coping with harsh conditions, and disrupt delicate habitats. Because decomposition and natural recovery are slow in arid conditions, damage from improper waste disposal tends to accumulate rather than fade, making recovery take much longer. So, waste disposal in desert regions is especially harmful when not managed correctly.
