Ahhh Sundays.....a day to snuggle up with a good book and a cup of tea. May I suggest a little green reading, such as 1001 Ways to Save the Earth! This book shows you that simple ideas can have major environmental impact. It has easy tips for every budget and everyday. From taking canvas shopping bags to the grocery store to purchasing green energy "off sets" to make up for unavoidable carbon dioxide emissions hmm...I have to purchase some "off sets" soon! What is even better is the book is printed with vegetable-based inks on paper from sustainably managed forests.
Couldn't get much greener than that!
A little green note: check out http://www.adoptalibrary.org/ they are great cause they keep old books out of landfills and donate them to American Indian Reservations, Correctional Facilities, Books for Africa and many more organizations.
