Many people will be enjoying themselves this time of year at numerous holiday parties. Treehugger has some great tips on how to host a party that should be a little more environmentally friendly.
Another thing to consider this holiday season is your own recycling. If you're into gift giving be sure to recycle as much of the packaging as you can. Check your local recycling rules to make sure you're recycling as many things as possible. I know it can take a lot of time but reducing the amount of stuff that goes to landfill could be one of your gifts to the environment this year.
If you're stuck for last minute gifts review my posts on green gifts and recycling old electronics if you have to get rid of some old ones. Enjoy whatever it is you're celebrating and keep thinking of ways to minimize your impact on the environment.
