I invite you to check out ProLifeSearch.com, a new filtered search engine for the web powered by Google. In addition to filtering search results using Google's 'SafeSearch' features (you can do the same with Google, but you first must turn it on in Google's 'preferences'), Pro Life Search will donate profits made through advertisements to many different Pro-Life organizations. You can read their blog or read their 'About' page for even more info.
I especially like this quote from their About page:
Who is ProLifeSearch.com?
We’re a privately-held company in Chicago, Illinois, founded and managed by two guys who both try hard everyday to be the good Catholic boys their mothers always hoped they’d be.
