The bamboo used in the Humble Brush comes from Ningbo, Zhejiang, an industrialized province in China. The bamboo plantations there are mostly grown on barren wasteland under the Chinese government's reforestation programme.

Due to its extensive root system, bamboo is able to thrive in soils that are depleted of nutrients, enriching them in the process. This can rehabilitate degraded land by improving soil quality and restore the water table. Instead of causing deforestation, your toothbrush is helping to re-establish ecosystems!

The Humble Brush is also “panda-friendly”. It uses Moso bamboo, a species of bamboo which grows leaves from 5 metres onwards. Pandas don't eat them because they can't reach that height, so you don't have to worry about your toothbrush depriving our furry friends of food.

What's more, being one of the fastest growing plants in the world, bamboo can grow up to 50 cm a day reaching up to 20 meters in height. Bamboo can be harvested within 3–5 years, which is up to 20 times faster than trees in some forests. It needs no pesticide, very little water, and very little fertiliser as fallen bamboo leaves provide sufficient nutrients. Finally, bamboo is carbon-neutral in its product lifecycle. The bamboo tree captures carbon dioxide during its growth, and returns it to the atmosphere when incinerated, emitting net-zero carbon emissions.
