Bob's wife's friend Takala is a scientist studying climate change. She's regretting that if as little continues to be done about the issue as is done today, by the time her great-grandkids would be around, (worst case scenario, but still,) there would just be just one sea left that hadn't fully evaporated like the Aral Sea already pretty much has today. For this reason she's decided a) not to have kids (because more people on the planet means more global warming, and because she figures it's cruel to bring kids into a world where things are about to get so much harder for the vast majority of people,) and b) to lobby as hard as possible for people and governments everywhere to take the issue seriously. Like the most serious issue on every agenda everywhere for the foreseeable future.
In her honour, this can be done with just one 'sea.'
