However, as I've witnessed far too frequently from people I'd still call friends here at FR, it's flat-out surprising who has been indoctrinated into believing there are too many people on the planet.
Please pardon my skepticism if this doesn't apply to you two, but I've seen far too many who become concerned over stories like this one, clearly the consequences of international policies, only when they have a personal stake in the deaths. Otherwise it's "oh well, ya know Av, the enviro-wackos do have a point." This is the "morality" of the new paradigm.
Have a good day.
