Sir Arthur C. Clarke, who resides in Sri Lanka, recommends a particular charity organization, Sarvodaya
, and says they are "the largest development charity in Sri Lanka, which has a 45-year track record in reaching out and helping the poorest of the poor. Sarvodaya has mounted a well organised, countrywide relief effort using their countrywide network of offices and volunteers who work in all parts of the country, well above ethnic and other divisions." I rather like that on their site, you can view photos of the relief efforts. Sir Arthur and his family and staff are safe.
I've actually spent very little time reading or thinking about this, because whenever I do, I get tense and choked up, and it doesn't seem fair to my students. I'll process later.
