Hi I'm a newbie so thought I'd just add my thoughts. I class myself as fairly green but not OTT, although I do belong to Friends of the Earth, BMA & the NCT so that probably tells you a lot about me LOL.
We have a two wheelie bin system in this part of Devon, bins are emptied fortnightly. Rubbish one week recyclable the following week. Although you have to take glass to a bottle bank, luckily we have one about 3 minutes from our house.
Have a sign on the front door saying No Junk Mail, or Free Newspapers, Please. It was amazing how much Cr## came through the letterbox each week.
Sons have pet rats, we used to buy expensive bedding for them, now I have bought a paper shredder and any letters bank info etc. gets shredded, don't shred newspapers they get recycled. Sons say it's easier to clean out the cages with shredded paper, than straw or hay less mess.
Have long life bulbs all over the house, apart from our bedroom which is a dimmer switch. If you put a long life bulb in a dimmer socket it blows the bulb, expensive mistake to make. Got our bulbs from our gas supplier on a good mail order deal.
I'm a meany and make the boys put a sweatshirt on if they are feeling cold. it's no good sitting there saying your cold in a T-shirt is it. If after half-an hour they are still cold they can turn the heating up.
I'm a Registered Childminder as is DH and we have used washable nappies on our minded children for 5+ years. Saves big time on the rubbish! Even started using washable wipes this year as well.
Bought myself some Lunapads washable menstrual pads, 18months-2 years ago, because I'd tried the keeper but it wasn't for me. I'm a funny shape because of stitches and it didn't fit! Anyway used Lunapads since and amazingly not had thrush since I've stopped using tampons, used to get it bad two or three times a year.
Pass on old magazines for mum to read who then passes them onto a friend who passes them on to another friend!
Just bought myself a classic old style (but new) ladies bike for Christmas, complete with wicker basket and skirt and chain guard so I can still wear my long skirts whilst cycling. Not been on a bike in 15 - 20 years, bit wobbly.
Invested in a vaporeto steam cleaner, cuts down on the amount of lotions and potions you buy in the cleaning section of sainsburys.
Must be others but can't think of them at the moment.
