Let's change our mindset about the world
Hans and Ola Rosling show that we know too little about the progress in the world and they explain how we can change that. Hans Rosling, founder of the Gapminder foundation, became famous for his TED presentations about the development of the world in areas such as health, wealth and environment. In those presentations he use Tendalyzer software which made them spectacular and dynamic (see here ). They were also surprising in their content. They showed that the world has improved, and is still improving, in many ways. Examples of such improvements are decreasing child mortality, decreasing extreme poverty, better and longer education, especially for women, increase life expectancy, etc.
