I was born in 1955 and the world's population was 2.8 Billion. Now, in 2019, it will approach 7.8 Billion, more than doubling in those 64 years. The news stories I saw on television yesterday were about the immigration issue where people are escaping violence, overcrowding, and poverty, stories about tourist areas like Venice being over run by visitors, and even Australia is concerned about their population.
The root of a lot of problems is just too many people. Economists say we need population increase to stem the financial system, but at what cost. Back in the 70's and 80's, we heard a lot about zero population growth but today it is a forgotten theme. The world's resources have a limit, and I wonder how far away from the hard limit we are.
