This thread is AWESOME, Janny!!
Re: the plastic bag issue, we use
Seventh Generation (linked to several times above) garbage bags... they are biodegradable.
We also use
Seventh Generation TP, napkins, dishwasher detergent & rinse agent, baby wipes (for DH... dont ask. 
) , and several other things that I cant remember at the moment. We shop through
Gaiam.com.
Does anyone know of any good eco/wildlife-friendly solution to algae growth in fountains/birdbaths?
