September 29, 2009 (La Mesa)-- “Be an Eco-Hero! Each person can make a difference and you can too.... Let your voice be heard!” read a sign at the City of La Mesa’s second annual Sustain La Mesa Environmental Festival. A number of young people showed they are well on the way to being eco-heroes and heroines, as they came to share what they know and make a difference.
