Green celebrities are hot in the news and they just seem to keep amassing in numbers.

More and more celebrities, not just from Hollywood, but all over the globe are strutting their green ways- from tree planting, to hybrid cars, green architecture, sustainability and much much more...

Getting green is getting cool, and if the rich and famous want to endorse the shift to thinking globally and acting locally, then I say, bring it on!!

And the stars get about as big as they come- green movie stars, green bands and green tv stars...
