                                 Saving the Planet with Earth-Friendly Bamboo Products

     Jackie Heinricher's love affair with bamboo started in her backyard. "As a child, I remember playing

among the golden bamboo my dad had planted, and when there was a slight wind, the bamboos sounded

really musical."

     A fisheries biologist, Heinricher, 47, planned to work in the salmon industry in Seattle, where she lived

with her husband, Guy Thornburgh, but she found it too competitive. Then her garden gave her the idea

for a business:She'd planted 20 bamboo forests on their seven-acre farm.

     Heinricher started Boo-Shoot Gardens in 1998. She realized early on what is just now beginning to be

known to the rest of the world. It can be used to make fishing poles, skateboards, buildings, fumiture,

floors, and even clothing. An added bonus: Bamboo absorbs four times as much carbon dioxide as a group

of hardwood trees and releases 35 percent more oxygen.

     First she had to find a way to mass-produce the plants-a tough task, since bamboo nowers create seed

only once every 50 to 100 years. And dividing a bamboo plant frequently kills it. 

     Heinricher appealed to Randy Burr, a tissue culture expert, to help her. "People kept telling us we'd never

figure it out," says Heinricher. "Others had worked on it for 27 years! I believed in what we were doing,

though, so I just kept going."

     She was right to feel a sense of urgency. Bamboo forests are being rapidly used up, and a United Nations

report showed that even though bamboo is highly renewable, as rnany as half of the world's species are

threatened with dying out. Heinricher knew that bamboo could make a significant impact on carbon emissions

(排放) and world economies, but only if huge numbers could be pmduced. And that's just what she and Burr

figured out after nine years of experiments-a way to grow millions of plants. By placing cuttings in test tubes

with salts, vitamins,plant hormones, and seaweed gel, they got the plants to grow and then raised them in soil

in greenhouses.

     Not long after it, Burr's lab hit financial difftculties. Heinricher had rlo experience running a tissue culture

operation, but she wasn't prepared to quit. So she bought the lab.

     Today Heinricher heads up a profitable multimillion-dollar company, working on species from all over the

world and selling them to wholesalers. "If you want to farm bamboo, it's hard to do without the young plants,

and that's what we have," she says proudly.
