The Baltimore Tree Trust, a new non-profit whose mission is to "Transform Baltimore with Trees," would like to join the citizens of Baltimore in expressing dismay at the removal of mature, healthy trees on downtown streets for the convenience of the Grand Prix. At a time when our urban forest is visibly in decline and only trees can help cool hot city streets, Baltimore should work with the race organizers to create grandstands where the audience would sit sheltered by the cooling shade of large trees. A win-win for all.
