Starbucks needs to stop selling non-biodegradable Teavana teabags

Teabags should be compostable. Despite the fact that I contacted Starbucks several times regarding the sale and distribution of Teavana nylon w/ plastic tabs teabags, Starbucks has ignored the issue completely. Why on Earth would any company make teabags out of nylon and then add a plastic backing to the teabag paper tabs? Starbucks needs to do the right thing and stop adding this kind of non-biodegradable trash to our landfills. Teabags don't need to be made of nylon and plastic.
