Step 2. At a larger scale, forests are described as carbon sinks and 'lungs of the planet' -- a functional description of forests continuously absorbing atmospheric carbon dioxide and, more broadly, buffering local air quality, so conserving existing forest (rather than losing it to deforestation) preserves this pollution-absorbing capacity.
Step 3. The chapter's own economic illustration reinforces this: a single healthy tree produces roughly 1,00,375 litres of oxygen a year (worth over ₹23 crore at cylinder-gas prices), underscoring how much air-quality value is lost per tree removed and, conversely, preserved per tree conserved. …
