It is great to see a proposed sustainable solution to an increasing problem impacting a community that did virtually nothing to induce that problem! It also seems win-win in that it is addressing a problem while enabling and enhancing the socioeconomic status of the local population.
To better understand the scope of the problem and proposed solution, it would be helpful to quantify the impacts and benefits if at all possible (in such complex systems, it may be difficult). Do you happen to have estimates indicating the current disability-adjusted life years (DALYs) and/or predicted DALYs as climate change increases, and how this proposed solution can reduce those impacts? (Since DALYs may be hard to come by, any indication of disease incidence and reduction would be informative, including population affected and current access to medicines compared with predicated access.)
Thanks for working toward business-based solutions to pressing global problems!
