Sustainability refers to using resources that can be replenished quickly, like bamboo, cork, and rubber. It is about ensuring current living does not negatively impact the future. Personal sustainability actions include recycling, using public transport, switching off electronics, and seeking grants for solar panels. Locally, one can buy local produce, use green waste centers, and support fair trade. Nationally, governments can support buses, wind farms, and solar grants. Internationally, policies aim to increase corporate responsibility and reduce disagreements between countries. Bioregionalism uses local natural materials appropriate to the ecology, economy, and culture of a region.
