Hans Rosling 6, Global population growth, box by box (script)
Summary
In 1960, the world population was three billion. Now in 2016  it grew up to seven billion. It's because the developing countries are given water, vaccination, education and some investments. They would use the aid well. Child mortality was really down. We think it's speed is too fast. Population growth will lead to other problems that are lacking food, energy  and using energy too much will lead to climate change.
Decreasing child mortality is a good thing. Precious lives are saved. We have to raise their skill up the places where the population isn't increasing  during those problems will be being solved. The developed countries should be good models  and help them before the world population is nine billion.  It's a very important role for people in the blue box.
