Can someone tell me why it was changed to print()? Philosophical reason or pragmatic?

Philosophical. Pragmatists like myself can't stand it.

If you believed Greenpeace, we would all be back in the stone-age since everything has some type of impact on the nature.

If you believe Greenpeace, the worst offenders are a) whichever companies get them the most publicity by attacking them (Apple, Nintendo, but not semiconductor makers consumers have never heard of) and b) whoever doesn't give money to Greenpeace.

Not long after we first heard murmurs Microsoft may be ready to lay off as much as 17 per cent of its workforce...

This has been roundly dismissed by many sources at least as credible as the initial "murmurs". (e.g. "The latest to report on the possibility of layoffs at the software giant is the blog Fudzilla, which puts the number of job cuts at 15,000, or nearly 17 percent of Microsoft's worldwide operations.") We'll find out in a week, I guess.

The Sierra Club ranks colleges by their greenness, and, curiously, the Ivies aren't in the top ranks. Places like Middlebury and Oberlin are. These are small colleges that focus on the teaching of undergraduates. Maybe that's part of why they seem to be leading green thinking.

Obviously major research universities aren't going to be competitive in "greenness" with small liberal arts colleges. If you think we're going to move away from the "carbon economy" by producing more BA's in Queer Studiez and fewer chemistry and physics PhD's ... there's a lot more to it than bong hits and "awareness".
