The importance of being good to the environment is one that is often balanced against the expense. Many families, especially in the current financial climate, will find that they can afford either food or principles, and in such a situation the latter is always going to lose out. However, the truth is that you can be green and live affordably if you know how, although you may not be able to do everything that someone with more disposable income might.
Having little money often means you cannot live as close to work as you would like. This may rule out the short walk to work and even cycling. However, if your area is served by public transport then this may be more advantageous than driving, as it will help the environment and you may well save some money on fuel. If you live outside the main shopping catchment area but have more local stores, then you may be able to walk there and back – although this becomes harder when the local store is more expensive.
Recycling containers is something that always benefits the environment and can help you make something of leftovers. Making more food and freezing some of it means that you cut costs that way, and use less packaging into the bargain. No-one is going to blame you for unavoidable compromises, and if anyone does then they are the ones with the problem. Not you. Doing what you can is a whole lot more noble than cursing those who do less than you can.
