Check It, Yo

I was reading TMQ (Gregg Easterbrook), and I was reminded of the important issue of tire pressure. Most drivers do not check this. It's dangerous and causes unnecessary, excess fuel consumption.

Read here on the Car Talk website about how to properly determine your car's recommended tire pressure. Of particular importance is maintaining proper pressure during seasonal changes -

"...if you last had your tire pressure checked in July, when it was 80 degrees outside, and it's now January — and the temperature is minus 20 — your tires may be underinflated by 10 pounds, which is dangerous."

Oil and Water

This is a tough one for me, since I'd much rather see people buying water than soda, but there is a growing movement against the bottled water phenomenon.

Gina Solomon, a senior scientist at the Natural Resources Defense Council, points out that "people complain about the cost of gasoline", but "no one seems to realize that they are paying for a picture of pretty mountains on the label and a product they could get for free from their own tap." She has a water filter at home and carries a reusable bottle for drinking tap water.

There are tons of reasons not to buy bottled water. Here are some of them on CNNMoney.
