There was some discussion up thread about Stephen Pinker's thesis that the world is on an improving trend of declining violence. Not that this isn't true, but it's an emergent property of increasing wealth. If/when wealth declines so will the trend of declining violence, along with other positive trends, such as declining wars, declining poverty, improving health and longevity, etc.
Ted Talks runs a weekly radio show of interviews and Ted Talk excerpts of people who have given Ted Talks, and this week's included Stephen Pinker talking about his book
The Better Angels of Our Nature, the one that Tangle referenced up thread that sparked this side discussion.
Also on the show was Paul Gilding, former Greenpeace director and a Fellow at the University of Cambridge's Institute for Sustainability Leadership. Gilding spoke about his book
The Great Disruption: Why the Climate Crisis Will Bring On the End of Shopping and the Birth of a New World. Gilding's thesis is that
The Earth is Full (the title of his Ted Talk), and that a number of current trends are running in the wrong direction, climate change being the most significant driver of change, but sustainability of resources, food production and pollution also being important. Gilding is optimistic, believing that civilization will survive, though not without massive catastrophes first.
Some conclude from Pinker's ideas that mankind is getting better, that we are learning. We are not. Evolution doesn't work that fast. We're still the violent, brutish thugs we were 200,000 years ago. Our wealth (i.e., our improving ability to take advantage of natural resources) has enabled us to evolve increasingly enlightened societies that emphasize freedom, happiness and health. But there's only one Earth, and as Earth's human population presses toward and then past 8 billion it will reach its limit of how much humanity it can sustain, particularly as we spectacularly fail to address climate change.
It cannot be predicted whether this will happen as a gradual decline or as a crash. I suspect the former, but punctuated by spectacular disasters of both climate and food. But whatever the pace of this change, it will bring with it increasing violence and decreasing freedom, happiness and health as nation states battle over resources with the nuclear threat ever present. Our primary hope must be that science and technology somehow win the race against climate change, but this possibility is in the hands of politicians who in many western countries, by far the most powerful block of countries in the world, are given power by electorates too dominated by blockheads swayed by the arguments of populists, scare mongers, haters and reality show hosts.
