谈电磁污染的风险时不光要讲大小,还要讲是否自愿,是否可控制。

Some people like to say watching TV also can bring electro-magnet pollution etc, etc to justify putting high power line on other people's backyard. This type of thinking neglects a critical distinction in risk assessment.

One has to distinguish between "voluntary" and "involuntary" risks, between "controllable" and "uncontrollable" risks. We all know TV can produce some radiation. However, once informed of the risk, people who still take this risk do it voluntarily. People can also control the risk by watching less TV.

A similar example would be that of driving vs. flying. Airlines often say flying is safer than driving. It is true, in statistics, but very wrong, with respect to the principle outlined above. The risk of driving is controllable by choosing safer vehicles and driving more carefully and defensively. I hate it when people lump me and some drunkards together to calculate the risks. But what can you do when flying? Take a helmet to the plane?

If I want to, I can donate thousands of dollars to a charity. But if you rob me of even one dollar, it's still a robbery. The same goes for taking risks.
