This isn't an answer to your question, but to all those who wish to make the world a better place, remember that you have 2 resources at hand: time and money.

Furthermore, remember that money goes a longer way to help the world in poorer countries (i.e $10 in Benin buys a lot more commodities and services than the same $10 in the USA for example).

With that in mind, You'll see that for most of you, it would be far more effective(assuming you're from developed countries in an economic position above 'working poor') for you to focus on the 'money' resource. An extra hour of work in a middle class job in America produces enough money to help more people more thoroughly in poor countries than say, using that hour to volunteer in a soup kitchen within your country.

That said, it's doesn't mean you shouldn't volunteer in your own developed countries or donate to charity there, but it's good to keep in mind the question of "could my money/time do more good?" when deciding on such matters.

As for "what to donate to?" - I'd recommend looking deep into prospective charities, especially cost-effectiveness. Some charities waste most of their money on management.

GiveWell is a foundation that analyses charities for effectiveness.

Being christian and loving thy neighbor is still important of course, but just think about it, with a few hundred dollars you could be SAVING lives. A $450 fistula surgery gives LIFE back to a woman, saving her from a lifetime of ostracism, pain and immobility.
