Raising total production is ineffective as a way to help the poor: almost none trickles down to them. Meanwhile, those who try to reduce their personal greenhouse gas footprint end up blowing all the savings. We need to change the system.

There is one form of personal greenhouse gas reduction that really does work: not reproducing. Each child multiplies your whole ecological footprint.

Wealthy people must reduce their reproduction because each wealthy child will consume a lot and produce lots of greenhouse gas. Poor people must reduce their reproduction because their children will have no prospects except desperation. (We have to give them reliable birth control to help them do this.)

Foreigners losing temporary protective status in the US are likely to start walking to Canada despite the risk of losing fingers and toes.

The University of Arkansas wants to fire tenured professors if they don't teach a subject the way they are ordered to.

Uber is being investigated in several countries for covering up a data breach instead of reporting it.

More important than this secondary outrage is the reason why Uber had so much data ready for crackers to steal: its practice of making users pay by credit card, thus providing the data to Uber.

If you ride an ordinary taxi, and have the common sense to pay cash, it collects no data about you, and no breach in the taxi company can touch you.

If we require all digital payment systems to pay the merchant anonymously, so that the merchant gets no information except "you have been paid amount X", this will prevent a large fraction of the data breeches that are likely to happen.

We must hold a debate on how to bring production down to a level that the Earth can sustain.

It will be hard to convince the people that live at a decent standard of living to accept the loss of many comforts. Thus, this debate needs to include bringing the human population down to a level the Earth can sustain. My guess is, around one billion people, roughly the number that currently live at a high standard of living. But perhaps it should be somewhat less.
