I urge you to donate what you can to the Hurricane Katrina relief funds. These people have lost everything: homes, photographs, clothing, heirlooms, furniture, businesses, food, toiletries, hospitals, computers, music, means of communication, books, clean water, medicines, cemetaries.
(Most) Katrina victims have lost all comforts; they've lost all necessities.
The least you can do is help out however you can..even if it's only a little bit.
What may seem like barely any effort, time, or comfort to you will mean the world to the survivors of what has become the worst natural disaster to hit the mainland in over 100 years.
