Hans Rosling’s Magic Washing Machine

This is another of several short pieces meant to preview this year’s Fall Ethics Symposium

Take about 8 minutes and watch this Ted Talk from Hans Rosling, the public health and statistics guru who tragically died from pancreatic cancer in 2017:.

There are a number of important lessons to take from his presentation (and you can watch the longer version HERE). I’ll focus on just two:

First, world population will increase. Predictions are controversial. Rosling has argued that it will go to about 11 billion by 2100 and then level off. At the time “The Magic Washing Machine” was recorded in 2010, world population was a hair under 7 billion; it’s now about 7.7 billion.

Some of this growth will occur in the poorest areas of the world. But this is because conditions for people in the poorest areas of the world are improving (as you can see HERE). When fewer of the children they have tragically die, population in these areas will increase a bit. Also, some of the growth will occur because people will continue to live a little longer. But most of the growth is explained by the fact that there are more people now who are below age 30 than above, and they will have children.

Second, more people will mean more energy consumption -- especially when there are more people who will be wealthier and have better lives (ones that will include magic washing machines). 

These inevitabilities inevitably raise climate worries, which have led to some pretty hard-nosed proposals to curb energy production and use. Is there a way to implement these proposals in a way that will allow everyone eventually to enjoy the magic of washing machines?
