Nothing goes down as smooth as a nice cool drink from TreeHugger Forums; here are some highlights...
1) Forums user tadowguy is crunching some numbers, and wondering about the relative greenness of synthetic versus dinosaur-derived motor oil. "I change my own motor oil in my car. 4 quarts (1 gallon) every 3,000 miles is the book's recommendation. That's about 25g of motor oil that I've used currently. It pales in comparison to the probably 3000 gallons of gas I've used, but used motor oil is nasty stuff. I switched to synthetic oil around 30k miles. The synthetic costs about 2x-3x the regular oil, but, I only change it about every 10-12k miles. Does anyone have any information on the impact of making synthetic oil versus refining motor oil?"
2) User shadygrove is new to the vegetarian lifestyle, and looking for some help. "I could use some advice, recipes, tips etc. about living a vegetarian lifestyle. I have no real interest in going strictly vegan, (i love cheese too much), but I am open to recipes that are vegan." A good "red sauce," to go with pasta and other starches, along with a handful of handy sites are suggested. In a slight tangent, one commenter suggests that the protein deficiency that can accompany vegetarianism is dangerous business...hmm.
3) Lastly, Forums user jcoffman has stumbled into a bit of a random question: "Ok, while wandering around the store the other day I found paper made from rocks.... I was initially skeptical, but still thought it was interesting. I looked up how this paper is actually made and I have to wonder, is it really better than traditional pulp paper? Obviously one could say its better because it doesn't require trees. Thats not the complete picture though. What about the manufacturing energy, and the biodegradability of this product?" Before you rush to click on over, there's already a few jokes about rock paper and scissors. Ha.
