Why doesn't someone drop food & water to japan?

Question:

Answer:

Water isn't a problem, as the world mainly consists of water.
Yes, the water may be dirty, but it is safe to drink if you boil and filter the water.

Japan is facing a lack of food supply, as many people are rushing to the stores and buying all they can to survive, and to stock up in case another disaster happens.

Organizations like Red Cross have been bringing in food to Japan, as well as other necessities.
