Donate $4 to sponsor a landmine sniffing rat
No despite the sound of the title this is no joke. With at little as $4 you can help the quest to remove landmine. The herorat.org project trains rats to search landmines because this is a cheap and reliable way to locate landmines with little risk to the rats. While the site has a cartoon appearance this is NOT a game – read the Press centre for media coverage (e.g. CNN). I donated.
