Hans Rosling 8, The magic washing machine (script)
Summary
You can know your world from the washing machine you probably use every day. Now, the world population is seven billion. Among this, two billion people live in poverty. Of course, they don't have it. They still bring water and heat it on fire to cook and wash. Ten billion people are the richest people. They use it. Four billion people in the middle seem to have electricity though people who use washing machine is one billion.
I was very surprised that only two billion have it but only they use over half of the energy in the world.
The washing machine makes us happy to have time to free head work. Economic growth is very important to make people happy.
Those two billion people must change behavior to use energy and use green energy. We prevent climate change and increasing population too much. And then, all people can have time to receive good education. The washing machine should be such magic machine.
