Social Science — CBSE Class 10 board question

Two ways to solve the problem of land degradation are:

1. Afforestation and proper management of grazing — Planting trees (shelter belts) and controlling overgrazing help restore degraded land.
2. Control of mining activities and proper disposal of industrial effluents — Treating and disposing industrial waste correctly reduces land and water degradation.

The textbook directly lists several methods; pick any two clearly stated ones. Examiners expect you to name the method and briefly explain it — one line each. Avoid vague answers like "stop pollution." Using exact textbook terms (afforestation, shelter belts, industrial effluents) scores full marks. This is a 2-mark question, so two distinct points are sufficient — no elaboration needed beyond a phrase of justification.
