The reason I think bamboo kitchen cabinets are such a good option is that bamboo is typically a more sustainable product than others. If you are trying to build en Eco-friendly kitchen, then bamboo kitchen cabinets are a great start. Some other things you can do you make your kitchen green friendly is to use energy efficient appliances and such. I also like having good faucets that save water. If you can have sustainable building materials, energy appliances, and faucets, then not only are you doing well by the environment. But you are likely to save money in the long run.
