health and well-being   . Not all green schemes are considered 'Nature-Based Solutions' if they do not benefit biodiversity, but carefully designed urban greening can be effective NbS. Careful planning also helps limit negative equity consequences such as benefitting wealthy neighbourhoods more than poor neighbourhoods . Effective planning should also consider what is appropriate for the climate and conditions of each city. For example, some trees emit volatiles  which, in the presence of certain atmospheric pollutants, can increase surface ozone which can, in turn, cause human respiratory problems . Wetland restoration close to human settlements needs to be paired with mosquito control to prevent negative impacts on human health and well-being , but it has been shown to provide better filtration and toxicity reduction with a lower environmental impact than other forms of waste-water treatment , including 'green roofs' and 'green walls'  .
