Throughout the DC Metro area and around the country, trees are cut down and relentlessly trimmed and their health often destroyed by homeowners, utility companies, and developers.  This de-forestation is collectively leaving us without critical habitat, shade, significantly minimizing CO2 emissions and diminishing our green space, the beauty of mature trees, and severely limiting the wide range of tree species throughout America.  If you are not already supporting organizations that are planting and replanting trees in cities and towns across the country, please consider doing so. I support Casey Trees here in DC and have also in the past obtained low cost young trees from the department of transportation to replant in areas where expanding highway systems have removed vast swaths of trees. In the spirit of encouraging you to think about how much trees mean to our lives and or ecosystem, here is a new study highlighting key actionable facts: Structure, function and value of street trees in California, USA.
