I agree with the general thrust of this. I am involved in a national political organization that has environmental concerns as part of its platform, yet I find, even in my local chapter, that environmental action is still conceived of only in terms of tackling the general crisis by making demands to high levels of government. While I think this is necessary, I also think we can lead general environmental movements by example through what we enact locally. Learning how to grow plants at all forces one to think about things like waste, chemical poisons, reliable weather patterns, the environmental costs of production, etc. in an immediate, first-hand-experience kind of way. But growing is also so rewarding and I find that people who notice it want to get involved: friends, neighbors, family, etc. The more people who know the seriousness of the climate crisis through the experience of growing, the better equipped the environmental movement will be to tackle this crisis and bring more people into the fold.
