Fun fact: Before there were expos, people had no idea how to disseminate information about sustainability. It was a bleak time. Luckily, events like Saturday's South Sound Sustainability Expo at the Greater Tacoma Convention and Trade Center have solved this problem, bringing "green" to the masses. According to yearly hype, the South Sound Sustainability Expo is "intended to provide residents and business owners in the greater Tacoma metropolitan area a place to discover services, products, companies, and agencies in our region that address sustainability needs in our community." As part of that goal, instruction and information on everything from urban chicken cooping to waste minimization and recycling will be discussed. Transportation alternatives will also be covered.
