Sonora Environmental Research Institute Inc
We work to create a sustainable world where there is environmental justice and opportunity for all people regardless of economic, ethnic, nationality or gender status. The communities in which we live and work have been disproportionately affected by pollution in the past and present and unless things change will be so in the future, especially as human-made global warming impacts the climate. These communities have the fewest resources to address the issues that affect their families and homes. We provide assistance and conduct research to create the capacity necessary to address these problems.
