Knoxville (WVLT) -- In 1982 it was the site of the World's Fair, but today to was where thousands of people flocked to promote a greener earth.
Earthfest 2007 ran throughout the day and featuring hundreds of exhibitors who were trying to help out the environment.
Seven years ago the event took place in Concord Cove Park but it has outgrown that location. According to some organizers, the reason may be that people are just more conscious of nature.
"Everybody's really trying to improve the environment, whether it be with cars, they have some cars out here," said Jerica Maclin who works with Keep Knoxville Beautiful. "They have some hybrid cars that take less gas, different gas and they just keep the glass clean, picking up trash everywhere they go."
The fest is doing its own part for the environment.
Organizers say it is a zero waste event and in all 10,000 visitors will only generate about 150 pounds of trash.
