Regarding Paul Brookes' informative but rather negative letter concerning the city's and Mayor Duffy's efforts to solve the greenhouse-gas emissions problem: Let me ask Paul and other readers to see if they have done as much as they can to help solve this problem by taking the following simple quiz.

1) Do you cook your food on an electric stove or use a microwave? Yes or no?

2) Do you cook your food on a gas stove or gas oven? Yes or no?

3) Do you dry your clothes using an electric dryer or a clothesline? Yes or no?

4) Do you dry your clothes using a natural gas clothes dryer? Yes or no?

5) Do you use an electric hot water heater? Yes or no?

6) Do you use a natural gas hot water heater? Yes or no?

7) Do you use electric heat to heat your household? Yes or no?

8) Do you use natural gas or oil to heat your household? Yes or no?

Score 1 point for every odd-numbered question you answered with a yes and subtract 1 point for every even-numbered question you answered with a yes.

These are simple and not too expensive things you can do to help reduce greenhouse-gas emissions. If you are worried that our leaders in the US automotive industry are leaving the automotive solution to greenhouse gas emissions to the Japanese, go to www.carenvironmental.com.
