Africa is booming. Per capita incomes since the year 2000 have doubled, and this boom is impacting on everyone. Life expectancy has increased by one year every three years for the last decade. That means if an African child is born today, rather than three days ago, they will get an extra day of life at the end of their lifespan. It's that quick. And HIV infection rates are down 27 percent: 600,000 less people a year are getting HIV in sub-Saharan Africa. The battle against malaria is being won, with deaths from malaria down 27 percent, according to the latest World Bank data. And malaria nets actually are playing a role in that. This shouldn't surprise us, because actually, everybody grows. If you go back to Imperial Rome in the Year 1 A.D., there was admittedly about 1,800 years where there wasn't an awful lot of growth. But then the people that the Romans would have called Scottish barbarians, my ancestors, were actually part of the Industrial Revolution, and in the 19th century, growth began to accelerate, and you saw that get quicker and quicker, and it's been impacting everyone. It doesn't matter if this is the jungles of Singapore or the tundra of northern Finland. Everybody gets involved. It's just a matter of when the inevitable happens.
