There are many worthy causes but it's best to donate where the need is greatest.

If you're looking for a specific cause to donate toward, I suggest giving for reconstruction in the wake of last year's earthquake in South Asia, where reaching the funding needed to address the aftermath is an ongoing struggle and the rebuilding process has been slow.

Another area in need of aid is the Darfur region of Sudan, where civil strife and a lack of political will around the world has left millions facing death.
