I know the green movement is huge right now and I'm a big believer in global warming. If you've never seen An Inconvenient Truth, you need to, because it's hard to argue with those facts.
Of course I recycle, cut back on water use and use environmentally-friendly products, but some other basic changes I've made include:
Composting - we've just started this process in our house and my son is so excited we are going to be making dirt (see pic)! Of course, he doesn't quite understand what having to wait a "long time" means. He likes to check the composter every day to see if we have dirt yet. It's a pretty easy process and kinda fun actually. You can find lots of resources on the net about how to compost, but I got my original idea from the book Gorgeously Green by Sophie Uliano. It has some great ideas of how to make your life more green, the girly way!
I've changed the lightbulbs in my house to compact flourescent bulbs. They are actually starting to make these in different shapes and sizes now vs. the basic spiral that has been out for a while, so it makes it easier to use these all over the house.
I've started washing all of my clothes in cold water. Evidently, your clothes get just as clean, you save money on your energy bill and it saves energy. In fact, washing clothes in cold water lets fabrics retain their color and strength longer.
I've also signed up for Greendimes, a company that removes your name from junk mail lists, reducing direct mail waste and they plant 5 trees in your honor. I signed up for the paid plan, and they sent me a really cool t-shirt, several compact flourescent bulbs, a reusable grocery bag - and they do all the work of removing you name off the lists for you!
So basically, it IS easy being green, if you make an effort to make some basic changes. You might decide it's kinda fun!
