The tsunami that occurred in Sumatra in December 2004 shook the entire world. The videotaped scenes of the horrific tsunami were seen on TV, and there are many people who have just now recognized the horror of tsunami. However, judging from the TV images, the intensity of the tsunami was minor except for Indonesia. Nevertheless, why was so much damage done?I regret speaking unkindly about the dead, but the fact is that the high casualties were the result of a lack of countermeasures against tsunami and a lack of knowledge about tsunamis in general.

Chronic marine contamination has a serious impact on creatures living in the sea, and is closely related to mass death, reproductive disorders, deformations and the declined immune function of living things. Investigations of Caspian seals that have died in large numbers several times in the past show surprising results that include the detection of dozens of times the concentration of organic chlorine-based chemical compounds in comparison with healthy Caspian seals. It is necessary to promote the reinforcement of an international monitoring system, and the establishment of an investigative research organization related to marine contamination.

The history of coastal areas along Tokyo Bay is closely related to laver cultivation. The cultivation of asakusanori (laver) used to flourish in Tokyo Bay, and asakusanori being dried in the sun could often be seen anywhere along the coastal areas. Our organization, Banzu Satoumi-no-kai, aims at the realization of satoumi where living creatures, fishermen and citizens can live together through a project for the revival of the perished asakusanori.
