Your fav eco friendly songs...

I found this cool article online today written by Mike Devlin at http://www.canada.com/, it was called  "Top 10 eco-friendly rock songs".  In honour of Earth Day today, he wrote this list of the top 10 rock songs that were both PRO EARTH and made an impact musically.  My fav is Big Yellow Taxi - Joni Mitchell.

1. Bruce Cockburn, "If a Tree Falls" (1988)

Songwriters and environmentalists love Cockburn equally, for his music represents unflinching activism. It's an ugly job, so give Cockburn credit. Without his many ecological laments -- of which "If a Tree Falls" ranks near the tippy-top -- our world would be a much colder place.

2. Joni Mitchell, "Big Yellow Taxi" (1970)

The view from her Hawaii hotel room -- a vista that was part pavement, part tropical nirvana -- inspired Mitchell to write her most famous song. Hawaiian Islands or Vancouver Island, the theme behind "Big Yellow Taxi" is universal. Sure, parking lots are necessary. But when paradise is paved to accommodate one, we all lose something significant.

3. Cat Stevens, "Where Do the Children Play?" (1970)

Tea For the Tillerman opens with "Where Do the Children Play?," a dreamy tune upheld by Stevens' softly sung queries. Stevens smartly hung his concerns over blind industrial progress on the fate of our children. And fans bought it hook, line and sinker.

4. Jackson Browne, "Before the Deluge" (1974)

There are Biblical overtones, to be sure, but "Before the Deluge" -- some of the finest California country-rock of Jackson Browne's career -- is about our mistreatment of the environment as much as anything else. Peter Gabriel bridged the same topic on his gem, "Here Comes the Flood," but Browne's tale cuts deeper.

5. Tracy Chapman, "The Rape of the World" (1995)

Tracy Chapman was everywhere, musically and emotionally, on New Beginning. During one tune she's singing about heaven on earth, and the next, how humankind has "clear-cut, dumped on, poisoned and beaten up" Mother Earth. Blind anger isn't always pretty. However, "The Rape of the World" proves it can be profound.

6. Marvin Gaye, "Mercy Mercy Me (The Ecology)" (1971)

A cunning character, that Marvin Gaye. By housing one of his most political songs inside a smouldering, soulful groove, he finds a way to make "Mercy Mercy Me" relevant and rewarding. "Where did all the blue sky go?" Gaye wondered. To which we respond: Where did all the political soul music go? Not since "What's Going On" have we heard genius like this.

7. Black Sabbath, "Into The Void" (1971)

Three months after Gaye released "What's Going On," these blokes from Birmingham issued the anti-war tirade, "Into the Void." Among the talk of "hateful battles raging on," Ozzy Osbourne sings of a diminishing environmental future. The combination of social conscience and bludgeoning riffs worked throughout Masters of Reality; Rolling Stone magazine placed the recording on its list of the 500 Greatest Albums of All Time.

8. Pixies, "Monkey Gone to Heaven" (1989)

Our relationship with the environment is considered by some a spiritual endeavour, a sentiment with which Pixies leader Black Francis would most likely agree. His first "hit" is a masterpiece of scream-sing aggression, laced with a toddler-friendly chorus and fetching high-register help from singer-bassist Kim Deal, but it's also a complex take on the earth's mistreatment. If you haven't heard it -- and we're nicking Chris Rock here -- y'all better recognize.

9. The Pretenders, "My City Was Gone" (1984)

Chrissie Hynde put her native Akron, Ohio, at the centre of "My City Was Gone," one of many highlights found on The Pretenders' career best, Learning to Crawl. The song's lean groove and the group's tragic back story (two members died of drug overdoses within a year) add emotional heft to Hynde's calculated missives, which are directed at "a government that had no pride."

10. Midnight Oil, "Dreamworld"(1987)

To see Oil singer Peter Garrett wail on stage is among the best concert experiences one could hope to have. When the towering front man puts his pen to paper, he's no less insurgent or tenacious. Garrett, defiant as ever, rails in "Dreamworld" against one of his old standbys: Environmental abuse."No amount of make believe can help this heart of mine." Rail on.
