A lot of my efforts to "go green" have involved using less chemicals around my household, which I think is more harmful than using plastic bags or bottles. For example, I use vinegar, water and baking soda for much of my household cleaning, rather than buying a bunch of cleaning chemicals. It works just as well! Instead of spreading pesticides around my garden to keep rabits away, I place used kitty litter around it instead. It really works! I remember when the 10th anniversary of Earth Day came around, and everyone was on a big "biodegradable" plastic kick...until studies revealed the biodegradable garbage bags were no better than the regular bags.
