From the passage: indiscriminate industrialization 'has created a state of decadence' (III). Man's tempering with nature 'has resulted in the threat to the sustenance of mankind' (II). The future generation won't sustain themselves 'if they inherit the present state of the world' (I). The industrial revolution 'led to drastic escalation of earth's surface temperature' (IV). So A-III, B-II, C-I, D-IV.
