@urlyman I read Limits to Growth when I was studying at University. As a BA Technological Economist I found it's feedback model approach pretty persuasive. It predicted that with exponential growth we would start to run out of (economically extractable) resources within my lifetime. It's big ommision was fossil fuelled CO2 emissions and the consequent feedback cycle screwing with climate. Needless to say I was being sponsored at Uni by BP and then joined the NCB when I graduated. Slow learner.
