But it's now more widely understood to be true. Nature can be harnessed to provide critical services for communities, protecting them against flooding or excessive heat, or helping to improve air and water quality, which underpin human and environmental health. When nature is harnessed by people and used as an infrastructural system it's called "green infrastructure." Green infrastructure occurs at all scales. While it's often closely associated with green stormwater management systems, which are smart and cost-effective, it's really bigger than that. Green infrastructure can be a centerpiece of smart regional and metropolitan planning, ensuring communities have a livable environment, with clean air and water, for generations to come. Green infrastructure can be designed to address the needs of wildlife, which are increasingly threatened by climate change, providing systems of corridors or greenways to enable movement through human settlements.
