Researchers have argued for example \cite{Bratman_2019}, that diverse stakeholders including city planners, landscape architects, and community-based organizations might be able to modify the natural environment in ways that promote mental health of communities. Intriguingly, research has demonstrated an inverse correlation between urban street tree density and antidepressant prescription rates in London, UK \cite{Taylor_2015}, even after controlling for measured and unmeasured confounders using Bayesian modelling. More specifically, a decrease of 1.18 prescriptions per thousand population was observed per unit increase in trees per km of street. It remains to be seen whether actually increasing street tree densities will have such effects. Sociostructural policy aimed at improving natural environments may further contribute to the reduction of inequalities, that will have further indirect impacts on wellbeing \cite{Bratman_2019}.
