This sounds an unlikely concept, but thanks to the advertising market, it is quite possible. By going the websites below and clicking on the buttons, you can donate to various causes entirely for free. This is because, by clicking on the button, you prove that you have seen the adverts displayed on the page, and the advertisers then make a donation to the cause. Brilliant!
I am always looking for more of these sites, because they are such a good way to prove that slow and steady and little and often wins the race!
Why not make this page your homepage and click them all every day?
It only takes a minute!
You can also find a lot of free information or goods for purchase at all these sites.

All the above links are part of one overall charity, so you can go to any of these sites by clicking on just one. They do a handy toolbar with a google search and a box for each site that shows whether you have clicked each day - and therefore reminds you to do it!
Check out The Hungersite's 'Goats for Rwandan Families', where the money you pay actually buys a pair of goats for a needy family: https://shop.thehungersite.com/store/item.do?itemId=26450&siteId=220&sourceId=46&sourceClass=Category&index=3 or their other mercy kits, which include School supplies for Afghan schools and school uniform for African would-be schoolgirls: http://shop.thehungersite.com/store/category.do?categoryId=253&siteId=220&adId=84871&ctgSource=ctgSource
At the bizarrely named Red Jellyfish.com, you can save rainforest, or feed chimps, both for free.
Also, see Red Jellyfish for a beautiful range of free ecards: http://www.redjellyfish.com/ecards.html and for fun and interesting ecological news.
Click below to go to the causes :
Global Warming, Rainforest, Breast Cancer, Ocean life, Big Cats, Primates, Children in Need, Pets in Need,
N.B. There is also a page where you can click to save baby seals from hunters if you've really got nothing better to do. I don't particularly see why hunting unendangered seals should be illegal, but there we are. There is also one more page where you can click to 'Stop Violence against Women'. Certainly a worthy cause but I do not choose to display a link to this because the sponsorship money is coming from the pro-abortion charity Amnesty International.

Click above for Youth Noise, which chooses a different charity each month to support. (Above picture, a previous recipient of free click funds, Heifer International, which helps to supply livestock to impoverished people.)
On the main site, Youth Noise, i am bemused to see a channel for Animal Rights complete with adverts for ALF, right along with a channel against Violence... a few wires crossed there, i think!
