One of the charities I personally support is KIVA - KIVA are a non-profit organisation with a mission to connect people through the use of microloans; lending to alleviate poverty.
Leveraging the internet and a worldwide network of microfinance institutions, Kiva lets individuals lend as little as $25 to help create opportunity around the world. This enables entrepreneurs to start or fund their businesses and make a difference to their own lives, as well as the lives of those around them.
KIVA envision a world where all people - even in the most remote areas of the globe - hold the power to create opportunity for themselves and others.
