We don't have to allow streets and air to be clogged with multiple delivery vans. We do not have to let rapid delivery be society's priority.

Professional US football systematically causes brain injuries, and players typically get many of them. The resulting damage often makes victims irrational and violent. A study of deceased former players' brains found signs of injury in nearly all of them.

I don't think it should be illegal to play football, but society should change the institutions that systematically attract people to the game -- such as the NFL.

Right-wing cuts in welfare benefits generally come with demonization of anyone who "cheats". The result is that everyone is likely to be suspected of "cheating" -- most of them falsely.

What about the few who really do lie? After all these cuts, it is quite plausible they wouldn't get money for food and medicine if they didn't lie. Maybe they could not care for their children if they told the truth.

I think those circumstances justify lying to a bureaucracy.

If the state wants to deserve to be told the truth, it should give decent treatment to those who do so.

We cannot expect to be able to remove CO2 from the air in the quantities needed to compensate for our excessive emissions now.

The proposed methods are either very expensive, very challenging, or very damaging to the environment.

The EU is considering a weak measure to promote use of tap water instead of bottled water.

Why not require (as France requires) restaurants to offer tap water? Why not label every plastic bottle -- of water, of other beverages -- with "Buying plastic bottles like this degrades the environment?"

We need politicians who don't hesitate to displease businesses.
