I think the key to adopting a more eco-friendly and ethical lifestyle is to make small steps, rather than the all or nothing approach.
For example, if you normally fly 3 times a year, reduce it to twice a year and take the train or drive the other time. For most people that is far more achievable than just giving up flying altogether.
If you are a meat-eater, try going vegetarian for, say, 2 days a week (will save money too).
If you normally drive to school, decide to walk or cycle one day a week.
Those are all things we do in my family. My eco-resolution this year (having given up shopping for a year in 2008, see earlier thread) is to have one TV-computer free day a week for the family when we do radical stuff like read books and talk to each other instead.
But you asked for three top tips for a novice, so mine are:
- Reduce energy consumption in the home (which means maximum insulation, low energy bulbs, switching things off, washing at low temperatures -- I'm sure you already know all that stuff).
- Shopping for food locally from independent retailers and buying fairtrade/organic where possible. Get a locally produced organic veg box and buy meat in bulk direct from farms, or support your local farm shop.
- Travel less and when you do, use pubic transport rather than driving.
Good luck - let us know how you get on.
