I just found that I can donate to local animal groups like Liberty Humane Society and Hudson County Animal League by using this search engine (donates a penny a search) and by specifying the charitable org:
http://www.goodsearch.com/
If you do online shopping, you can also use their link and a percentage of the sale will be donated.

I'm sure many other local charities can be used. I just checked those two.

It seems to be a decent search engine so that's my new homepage at work. Makes me feel better about surfing the web during business hours!
