Luckily, Ann and her daughters found a group a like-minded girl scouts and formed a group proudly known as the "Eco-Warriors."  Ann and the girls have worked on many projects, including partnering with The Climate Project to organize a community event called “Climate Change - Kids Making a Difference” that drew about 150 people.
