Petal, I am so sorry about the loss of your good friend. If I could, I would go to your house and walk with you every day after work to help keep you company while you grieve.
On our trip back from San Francisco, we passed a town where I used to live outside of San Francisco on the coast. It used to be the last big town before all the lands that the California Coastal Commission protects between San Francisco and the towns an hour drive south. Now the cute little towns in between are growing rapidly, and it seems like the Coastal Commission is only protecting the lands on the ocean side of the coastal highway, and there are 100+ acre farms for sale that will probably be filled in with the creeping crud of civilization. The city where I was born used to all be orchards and is now solid city. I really empathize.
I feel like a lot of this is that there are a lot of people on automatic grabbing power or who are after security, and the underlying unexamined thing that they are trying to satisfy is a fear that if they don't do what they are doing, they won't get ahead in the rat race. We are up against a big "me first" old way of thinking that has to go. I think what we can do as individuals is to create a "we" way of being in the world so that others see that this is no only possible, but a lot more desirable. And I don't think this has to be some huge political statement, it can be an accumulation of small things we do every day like put out bird seed for the birds who can no longer live in the places that were built up, sign petitions for the causes we believe in, buy food and goods that are responsibly grown or made, clean up litter, and help other people who are doing similar things. I think this has to be grass roots because the people in power are addicted to power and are unconscious and unhelpful in too many cases. I think the more we create a good place to live on the planet, the more other people will be inspired to as well.
