You Can't See A Forest Without Trees -- Strike for the Planet week 115 [1] ['This Content Is Not Subject To Review Daily Kos Staff Prior To Publication.'] Date: 2023-10-26 You can make a difference to the hurt being caused by climate chaos and the great extinction event in your town or your city! How? Reuse, repurpose, and recycle this information. You can push your local politicians to act. It will make a difference! This is the letter for week 115 of a weekly climate strike that went on for 4 years in front of San Francisco City Hall, beginning early March 2019. For more context, see this story. For an annotated table of contents of the topics for all the strike letters, see this story. Meanwhile… STRIKE FOR THE PLANET “I think that I shall never see / A poem as lovely as a tree”1 This week’s topic: You Can’t See A Forest Without Trees SF needs to be planting more trees now! Why? Trees are a Racial Justice issue Formerly redlined neighborhoods are hotter than non-redlined neighborhoods. There’s a direct correlation between 1930s federal government Neighborhood Ratings2 and average neighborhood temperatures, with D (“Hazardous” or redlined) and C (“Definitely Declining”) neighborhoods up to 20° F hotter than B (“Still Desirable”) and A (“Best”) neighborhoods.3 Cities in the west, such as San Francisco, have the largest temperature differentials among such neighborhoods4, and the redlined/D areas in San Francisco (and many of the C neighborhoods as well) remain predominantly poorer and communities of color.5 What did redlining do to cause this neighborhood temperature differential? It kept trees out of the neighborhoods where poor and BIPOC people were allowed to live.6 This tree disparity is nationwide, enormous, and growing larger.7 In SF, the correlation between neighborhoods that were labeled D and C and lack of trees is clear and deadly.8 Why deadly? Trees provide vital environmental services We need trees. Trees provide shade, promote physical activity, form bio highways, store carbon, store and manage water, reduce water loss, reduce air pollution, provide food for native and migratory species and for us, calm traffic, create safer walking environments, promote mental health, provide positive community identity, cool air, make oxygen, increase property values, and much more.9, 10, 11 sources: FAO and Ecología Verde What is San Francisco’s tree policy? SF’s tree policy is bad, broken, and making things worse A city that values equity and justice and understands the importance of green infrastructure would be doing everything it could to increase overall tree coverage, especially in poorer and BIPOC neighborhoods. Yet San Francisco is actively reducing the number of trees citywide.12 San Francisco cares so little about the urban forest that there is no coordination whatsoever when it comes to trees.13 Not only are more trees being removed than are being planted, but the majority of trees being planted in SF are non-natives.14 Non-native trees take water from native ecosystems without contributing to those ecosystems.15 Non-native trees speed up the release of carbon from the soil into the atmosphere.16 And large swaths of the non-native trees in San Francisco are a substantial fire hazard.17 The solution is clear and simple Because trees save energy18 and lungs, lower heat, increase soil moisture, support native ecosystems, store carbon, and provide precipitation nuclei19, we must plant and maintain an urban forest of majority native trees. Your job is to find and enact solutions If SF is going to survive, you must act.20 You are bound by the Precautionary Principle, so you must act. You fought for this job, so you must act. To do otherwise is to engage in necropolitics21, which is not a good look for a politician, and so you must act. You must act, you must act, YOU MUST ACT. The trees need you to, and so do we.

Visit https://www.sfpublicworks.org/plant-street-tree to see the mess that SF provides instead of useful and easy-to-follow tree planting information. If you manage to navigate to the list of recommended trees (not easy to do), you’ll find the overwhelming majority of trees are non-natives.
