Bamboo seems like an environmentalist's dream come true. It's a self-regenerating plant that grows so fast (without pesticides and with little water) that it's considered a weed, and it can be used to make products from furniture to coffee filters.

But bamboo, like most things marketed as "green" these days, isn't perfect. First of all, much of it comes from Asia, so the carbon footprint of shipping it here is not insignificant. And though bamboo absorbs carbon, there is concern that, especially in China, demand for bamboo is leading to the clear-cutting of old-growth forests.

How not to get bamboozled? Do your homework. Until a global certification standard is devised, it's up to companies to use responsible bamboo -- and up to consumers to pay attention and make their preferences known with their wallets.

A few things to keep in mind:

The bottom line: Bamboo can be a smart alternative to wood products, but don't assume it's synonymous with sustainability. Check with companies before you buy, and don't buy new if you don't really have to.
