GPT explains (level =C2; CEFR aligned): Loss of global forest area during the industrial era → ≈ 40 % Reconstructions based on historical land-use datasets (e.g., HYDE, LandCover6K) indicate that pre-industrial closed forests covered ≈ 62 million km². Continuous cropland expansion, timber extraction and pasture conversion between 1750 CE and the present have removed on the order of 25 million km², a contraction of ~40 %. Although regional trajectories differ (temperate afforestation vs. tropical deforestation), the net global signal remains a loss of roughly two-fifths of the original forest estate—a central figure widely quoted by IPCC Working Group II and FAO Global Forest Resources Assessments.
