I would say that some of the stuff people are doing go beyond the "little things"...good work tree huggers!
I will mention your Mom as a resource to my husband for sure. He's the would-bee bee keeper in the family. Between the baby & our diabetic elderly pug I have enough beings to care for! He's always been interested but after our trip to NZ (bee boxes everywhere there) he's looked into it more seriously but missed the time of year to start one year, then the whole baby thing took over. Maybe next year.
You guys might also look into coldframes rather than a full blown greenhouse since you're so handy with your planters. it might be an easy conversion.
We're also part of a hand-me-down chain of kids stuff both from our neighbors and then down to my future niece. Our cloth diapers will get used by another set of neighbors in another year or so, we hope!
We've landscaped our yard as one big garden, no lawn, minimal watering necessary, no chemicals to upkeep and just a few borders that need to be hit with the weedwacker. Lots of hardscaping in the back was provided by reusing the stone from the old flagstone sidewalks and curbs my town pulled up on my street a few years ago. (we heard the ones from the other side of town still had rings to tie your horses to...would have loved to have some of those). We planted an orchard of baby trees in our backyard the year we moved in with peaches, apples,pears, plums, cherries, figs and bushes for blackberries, blueberries, gooseberries, currants and we have grapes, kiwis (yet to have fruit), hops and we moved in with two old mullberry trees. (also have a prospering erb garden) After +8 years here we're able to can enough jam that we don't have to buy any unless we want to and we get a really good harvest of plums & cherries.
My main source of food trash are soy related, so I recently bought a soy-milk maker & tofu form so hopefully I only have to buy bulk soybeans from now on.
We started using a solar oven this year for slow-cooking things, roasting, and even baked goods. (I hate running the oven in the summer but love making zuchini bread, conflict resolved!)
...and with the bulk food, canning & sun oven I find myself shopping on websites aimed at survivalists...wheee!
also on the food front, I've also started meal planning in advance on Sundays. I make my food shopping list based on the week's menu, take leftovers for lunch and try to incorporate what is left into next week's meals or freeze it. We have very little waste at the end of the week. less waste is more green, yeah?
We spend more for stuff that lasts and make good use of our local library for books, music and movies.
We purposly moved 2 blocks from the train station and walking distance to shops, resturants, etc. I'd like to think the latter is because I'm green, but really because I like having a couple of drinks and being able to walk home. I used to take the train to work every day but my datacenter moved and now I have to drive 45min 2-3x a week. My rav4 is pretty good on gas but I'm looking forward to all the promises most of the car manufactures seem to be making for new fuel technology in 2010.
and on a complementary note, if anyone wants black-eyed susans, day lillies, blackberry vines or hops they are easily thinned and shared.
