TL;DR: 10 instinct that distort our worldview.

By 2100 the worlds population will reach 11 Billion people. This is not a linear extrapolation of the current trend. In fact we have reached peak growth. Families tend to have less children the better the education of the women, the better access they have to contraception and generally the higher their income.

First steps to help with extreme poverty: Education, access to basic health care. Child mortality is at a low time low. The belief “advanced western world vs the emerging eastern world” is outdated. Most countries have reached level 2 with level 4 being the standard of living we consider normality. Still 1 Billion people live in extreme poverty.

Global pandemic, climate change, financial collapse, world war and extreme poverty the known threats to mankind.
