Canonical, the financial backers of Ubuntu, are donating 50% of profits made from the sale of music via the UbuntuOne Music Store to the Iberian Lynx conservation organization ‘SOS Lynx’.
Only 150 individual Iberian Lynx currently exist in the wild. Were it to suffer a further decrease in population and become extinct it would be the first feline species to become so in almost 10, 000 years.
So open up Rhythmbox and help support Ubuntu, your favourite artists and, most importantly, the preservation of the Iberian Lynx.
