ooooh I'm liking this Abs! Great work on initiating this, what better place to start than inspiring friends. I have included a link below to a website that gives you tips on how you and your household can reduce their impact on the environment + save some $$ too. You can create your own 'next steps' plan which is quite handy as often its hard to think 'well what can I actually do'..
Think of your house as an extension of your skin, it needs to breath just as much as you need to. Therefore using chemical heavy cleaning products is like spraying them directly on to you skin. Unless you are airing your house daily, you skin is absorbing all the leftover residue.
