Use this as your Google. Does exactly the same job, but it donates a whole one pence to a charity of your choice every time you search. This may not sound much, but considering the amount of people using it, and the amount of searches done per day, it all adds up.
NOTE: No money will be donated unless you enter a charity. Instructions are on the page's main page.
