It's all about the money. You can take many meassures to make the world more disasterproof. But are people willing to pay for it? The simple fact is that govermants and company's only have a limited budget for various importent issues and company's abviously want to make a profit. More funding for one issue, means less for another one.

I don't think a normal citizen can do much about the powerlines. It all depends on the intire infrastucture.
