It seems like green-tinted celebs are working overtime these days -- joining causes, donating time and money and making others aware of important issues. Many of them get a lot of flack for missteps and moments of bad judgment, but we think these entertainers are doing a lot more good than harm; by almost anyone's standards.

Drew Barrymore - Some people criticized her for naively praising the primitive lifestyle she encountered in third-world countries (while traveling with privileged friends by helicopter) during the filming of Cameron Diaz's environment themed show Trippin’. Barrymore’s new post as Ambassador Against Hunger for the UN World Food Programme shows she’s not just looking with astonishment at other cultures’ ways of life, but helping to change them for the better.

“I can’t think of any issue that is more important than working to see that no schoolchild in this world goes hungry.” - Drew Barrymore, WFP release.

Bob Geldof, organizer of Live 8 and Live Aid, criticized the upcoming Live Earth concerts saying no one needs to be reminded about global warming (has he been to North America lately?). He also contends that without any concrete measures being announced the effort will have no impact on global warming. Getting to the real point behind his rant, Geldof whines that the name Live Earth sounds too much like Live 8, saying they’re "getting lots of responses from people who think we are organizing it." Sounds like a little bit of activist jealousy to us, can't they just all agree they're doing some good and get over the petty things?
