I enjoyed reading this conversation about using plastics.
Here is my opinionated opinion. I am a very cheap guy. The less I spend, the less stress I put on the environment. At the same time, the less I spend, the more money I have to invest in stocks and bonds. My clothing and car looks well used. I never go to the movies. I am too cheap to eat out. I do not go on vacations. I even stopped buying the occasional can of beer. But, I am happy.
The best things in life are cheap: a beautiful thunderstorm, a cool breeze, or walk in the park.
Give me a $1 kite and I can make it dance, dive, and glide all day long.
