In the context of population growth, the logistic function means that something has made it stop. He dealt with this is the second video - he says we'll get zero population growth one way or another, because exponential growth forever is impossible.
Around minute 7 of the second video (did you actually watch it?) he points out that many of the checks on population growth are generally considered bad things - war, famine, disease (the alternative being birth control). This is hardly a reason not to freak out.

Yes. many of the checks on population growth are generally considered bad things - war, famine, disease The countries with the lowest population growth (e.g., Germany, Italy, Bulgaria, Japan) are among those with the least war, famine, and disease. Something else is going on.
- presidentender 16y agoDo you notice that the countries with the lowest population growth were severely battered in wars during the last century?
- mhartl 16y agoItalian birthrates aren't low because of Il Duce. Once people reach a certain level of wealth, they voluntarily stop having lots of kids.
- BoppreH 16y agoThere were many other reasons listed, including low immigration, small families, contraception/abortion, abstinence and pollution. This checks do apply do the countries you cited, but the list is still far from comprehensive. They are far better than war, famine and disease, but still regarded as bad things, which is the point.
- mhartl 16y agoThe dominant source of low birthrates in rich countries is people choosing to have smaller families.
