TUCSON, Ariz. -- Hundreds celebrated the environment and learned more about preserving its resources Saturday.
It was all part of the 17th Annual Tucson Earth Day festival and parade at Reid park.
It was a show of all things 'eco.' There was recycling, alternative transportation, and various forms of flora and fauna.
The theme of this year's Earth Day festival, "Conserve today-- preserve tomorrow."
"When they're in the shade then they stop," said
Solar powered fans attracted some inquisitive youngsters and around the corner, budding scientists conjured up ways to innovate the technology.
"Current chemistry research is actually looking into making cheaper solar cells and to do that they're using different materials," said Brooke Beam American Chemical Society
Students used fruit juice to create low cost solar equipment.
"So the blackberry juice absorbs the light and the titanium dioxide is used to separate the charges," said Beam.
If you don't want to wait for the tomorrow's technology, how about a thermal mass wall to insulate your home and drive down your electric bill.
"You keep what's going on on the outside outside and what you want to do on the inside, whether it's heating or cooling you store that on the interior of the wall," said John Wesley Miller.
Volunteers for the Audubon Society promoted appreciation for nature.
"They're working on face painting and helping kids families to make bird feeders that sort of thing. Just working to get kids to feel a little more connected with birds and nature," said volunteer Scott Olmstead from the Tucson Audubon Society.
Re-using, researching and respecting the earth.
The first Earth Day was held on April 22, 1970, intending to inspire awareness and appreciation for the earth's natural environment.
