85 years - that's quite a kick she's given that can. Sounds about the right timeframe to move the whole thing into science fiction territory. I have always reckoned that fifty years from now the issue will have gone away anyhow: a combination of natural population-peaking and the kind of unforseeable technology-breakthrough that can't be predicted exactly, but always happens. Given, of course, that there is absolutely no shortage of energy on the planet. Solar PV is an obvious candidate, but maybe electricity storage, or both, who knows? (Thorium-heads to the comments column, please form an orderly queue.) There's no shortage of people working on these things, night and day: as they say in academia: if you come up with a viable means of bulk electricity storage, you can name your university after yourself.
Meanwhile: let's see her give that pesky Greek can a hoof. Big boots needed, though, to avoid a painfully stubbed toe.
