San Francisco calls for state ban of clearcut logging and other factory tree-farming methods



On Tuesday June 24, the San Francisco Board of Supervisors unanimously approved a resolution to call on the state legislature and governor to enhance protections for California’s forest watersheds by banning factory tree farming methods based on clearcut logging and toxic herbicide application.

“In keeping with San Francisco’s leadership in the environmental justice movement, I felt compelled to collaborate with the Sierra Club and environmental leaders to introduce this resolution urging the state to stop these destructive clear cutting practices,” said resolution sponsor Supervisor David Campos. “It is incumbent upon us public officials to take a stand and fight to protect our natural resources. San Francisco’s pristine Sierra water supply and greenhouse gas-free hydro power, the integrity of the planet’s climate, and the security of wildlife and human health are intimately dependent on the health of our forests. I am proud that we received unanimous support from the Board of Supervisors for this measure.” Read More >>
