I ran across a headline yesterday that Russians produce some 40% of their food in dacha gardens. Once you grow it, the smart thing is to preserve it, and stow it in a root cellar for winter. The wife sent me a link for a prefab root cellar that probably costs as much as our house. A friend posted a link for DIY greenhouses built partially into the ground, but we have too much shale to be digging into the ground.

I predict that the global food crisis will be in the 2030s-2040s because of the population growth (not global warming).

What people have to do is start producing their own food in their backyards year-round…this should be practical and affordable for most people.

If people don’t do this we will run out of food, food prices will go up dramatically…there’s no stopping it….it’s inevitable (although I can’t pinpoint the exact time that it will happen, it WILL happen eventually).

We’ve spent 100 years increasing fecundity in the 3rd-world by providing them with technology in the industrial, agricultural and medical fields.
It is high time we provided them with whatever is needed to reduce that fecundity down to something that is *at most* replacement*.

Well, most countries are either – headed in that direction, India, and a few others, or – already there, Bangladesh, Vietnam. (From memory but that’s about right.) I sued to recommend this TED talk because it showed why populations will continue to increase despite birthrates being at or below replacement rates.

Now I want people to look at the admittedly clever demonstration at the end showing that a 9-10 billion population is inevitable through different eyes. If you watch you’ll see an unspoken presumption working through the numbers. That presumption is that generations are fifteen years. It’s absolutely true that a lot of women in the world do start having children at that age. What I do nowadays is play with those numbers.

If the average age at first birth of a child for women is increased by 5, or 10, or 15 or more years, what effect does that have on population numbers? Take two extremes as examples. In one community, women have only 2 children but the first one is born when they are 15 years old. In the other community, women also have 2 children but the average age of first birth is 30. So you have women in one community remaining childless until 30, in the other community women become grandmothers at 30, great-grandmothers at 45, great-great-grandmothers at 60, g-g-great-grandmothers at 75.

Good health care (the communities should be identical in everything except maternal age at first birth) means that women’s average life expectancy is 80. By the time she dies, how many descendants should there be at the funeral? To make it easy we’ll presume that every woman has one son and one daughter and we count children only once, so we count daughter’s children only.

Woman 1 adds 2 children added to her family every 15 years.So she has 10 descendants by the time she dies. Woman 2 adds children to her family every 30 years. By the time she dies at 80, there are only 4 descendants. (You’ll notice if you play with the numbers a lot, that you can construct scenarios where women can have more children but smaller aggregate families than women who have children and grandchildren a lot younger.)

In the real world, the changes possible are a bit smaller than this, but they are large. What you want to do is to reduce the number of generations in families, not just the numbers of children. The only way this can be done is by education and employment of girls and women.

Watch the talk, but change the way the boxes are added at the end. (That part starts around 10:30 in.) https://www.ted.com/talks/hans_rosling_religions_and_babies
