Good morning. 
I was just reading some pages from the activist guidebook that accompanies the Living Downstream film (www.livingdownstream.com).
I had to copy down Sandra Steingraber's observations about people, activism, science and hope.
"The first observation is that science and citizen activism can work hand in hand. ...  
"... second ... most people
 are intensely curious about the ecology of their own community - 
especially if they perceive that its integrity is threatened. ...
"... third ...what too often dampens
 all this cooperation and natural curiosity is a paralyzing blanket of 
fatalism.  Fearful of despair, many people decide to not investigate 
environmental contaminants.  They have convinced themselves that these 
problems are intractable and unsolvable, so why learn about them?  That 
attitude runs counter to the fighting spirit that cancer patients bring 
to their medical lives.  Instead of defeatism, why not bring that same 
bravery and hopeful determination to the circumstances of our 
environmental lives?
"When caring for the critically injured, emergency responders are trained to say, 'I'm not giving up on you'. That's the same message
 an Ethiopian farmer encouraged me to carry back to the place where I 
grew up.   Surely it's a phrase that applies to all the communities where we live.  Our fish.  Our rivers.  Our homes."
Steingraber's work focuses on environmental contaminants and links to cancer and other health problems. 
Her three observations seem to me to apply to a wide range of citizen activism.
1.  Science and citizen activism can work hand in hand.
e.g.
 The science of interactions between plants and soil organisms shows 
that having a planted area with many types of plants that decompose in 
place, retains moisture in the soil, increases nutrients in the soil 
which feeds and strengthens plants, and develops soil that is able to 
take in moisture.  Citizen activists wanting to maintain green space in a
 new housing development can look to this science.
2.  Most people are intensely interested in the ecology of their own community.
e.g.
 Community walks are invariably popular, whether they are tours of 
heritage buildings or nature walks through environmentally significant 
areas.  If the groups that lead such tours plan into their presentation 
direct ways for walkers to communicate with city planners afterward, how
 many more citizen activists might there be?  This action could be as 
simple as having people fill out a postcard size comment that will go to
 a city committee.
3.  We need to find ways to face, handle and move beyond despair and fatalism.
e.g.  Not having the morning clock radio come on to news would go a long way towards this!  Serious stuff before we even get out of bed in the morning is paralyzing!  I'll think more on this one.  But it involves one step at a time, joining with other people, and having some fun along the way.
We're all waiting for wind and rain from Hurricane Sandy.  Let's keep our fingers crossed for places like low-lying New York state coastal areas. 
Best regards.

Hello everyone,
I hope you are all well.
Shadow cat has taken over my office chair, so I watched the entire Edible City: Grow the Revolution video standing up and doing stretches.  Take that as showing how interesting it is!  Full of ideas, interesting 
things to see in the locales.
A link to the entire movie is on an October 17/12 entry

Director and Producers of Edible City
The blurb: Edible City is a fun, fast-paced journey through the Local Good  
Food movement that’s taking root in the San Francisco Bay Area, across 
the  nation and around the world.Introducing a diverse cast of  extraordinary and eccentric 
characters who are challenging the paradigm of our  broken food system, 
Edible City digs into their unique perspectives and  transformative 
work, finding hopeful solutions to monumental problems. Edible City - movie website: http://ediblecitythemovie.com/
This is to be watched several times!  Michael Dimeck, of a group called Roots of Change said something that particularly caught my attention.  He said that if the local [self-sufficient, organic] food movement is going to be a movement [and have an effect on communities and policy] it has to develop language and be able to speak its ideas to different communities.  I figure he's including politicians as a community, and the big agriculture advocates.  That's going to be hard ... it's hard to find the place to begin a conversation with  people you figure going in won't agree with you, or want to talk to you.
I guess we'll have to start with Pam Warhurst' idea "If you eat, you're in" that she speaks in the Incredible Edible Todmorden TED talk.
Well, just a quick post. 
Best regards,
