And a highly authoritative writing came well before that, written by God Himself, called the 10 Commandments. One of them specifies “Thou shalt not kill.” I think that and others can also support the notion that we should not destroy or harm other people’s property or livelihood.
Since people are dying from GW (from heatwaves, droughts/famines, disease spread, etc.), and people’s property and livelihoods are being harmed from it, and we humans are for the most part causing GW, then that and other commandments apply.
I didn’t need a PhD in Moral theology to understand in the late 1980s, when I became aware that GW may be contributing to droughts and famines in Africa, that I myself had to do what I could to reduce my emissions, and tell others about the issue.
To our astonishment, my husband and I found we could lower our direct and indirect GHG emissions while saving money and without lowering our living standard, down to some 60% below our 1990 emissions. I would have been willing to lower my living standard and spend money with net loss (I was becoming an OCDS Carmelite then and making a promise of “poverty”), but my husband wasn’t so willing, which led us to find these money-saving solutions – and that’s great, since I can honestly tell people now:
“Don’t be afraid, you can mitigate CC without losing anything or lowering your living standard. Don’t be afraid, Jesus is with you a;ways. Seek ye first the kingdom of God and its righteousness and all things will be added unto you. Hallelujah!!!.”
