More than half of the world's population lives in cities, far away from large parks and Mother Nature.
That's why, one day a year is set aside to help people reflect on the importance of conservation.
Forrest Park Nature Center has a festival like no other.
Hundreds come to listen to the music, but not just to hear the high notes. They want to listen to Mother Nature as well.
"If everyone were to live at the American rate, level of living, we would need at least 4 additional planets. It's really easy to see all the reasons why we need to try to conserve and protect the environment" says Naturalist Christina Kiefer.
Kiefer helped organize the 10th annual earth day festival.
“We have everything from recycling to conservation.”
Susan Sanders is a member of the Prairie Fiber Arts Guild.
She says - spinning wool is good for the soul....
"You sit at the spinning wheel, you get lost in the action. Very relaxing."
And Sanders says it's good for the environment, too. Common polyester fabrics don't break down easily. Instead, she says they just add to landfills.
"Yes, you can go to Wal-mart and pay $2, but if you make your own... It's kinda nice knowing you knit your own socks out of the wool that you spun."
Sanders along with many others are trying to make a difference. Whether it's recycling, composting, or cutting back on frivolous purchases, conservationist say every bit helps.
"Some things are beginning to move along and we are making progress. We just need to keep at it and keep going" explains Bob Jorgensen.
Hoping to save the earth, one small action at a time.
