At one time, few people lived permanently near the edges of the world’s oceans. Now, more than half of the world’s population lives near beaches and estuaries. People in developed countries have primary or secondary homes there to enjoy the views and for recreation. Poor people in developing countries live there to engage in fishing, jobs in tourism for people from developed countries, and for subsistence farming in river delta areas. They remain despite persistent hurricanes, typhoons, and resulting flooding. There is a serious disconnect for both rich and poor people between the reality of living near oceans and the danger that this entails. For a variety of reasons, people are becoming less and less connected to the world around them. Natural events that have devastating effects on humans are considered to be strange and unusual, rather than a normal part of human existence on a continually changing planet. Our disconnect from nature has serious consequences. Earthquakes under the oceans, from shifting tectonic plates or volcanic eruptions, are known to result in oceanic disturbances that result in elevated wave activity near ocean shores. A high wall of water, or wave, that emerges from the water column caused by an ocean disturbance is called a tsunami (Japanese for “harbor wave”). Globally, 80% of tsunamis occur in the Pacific Ocean region. Seismic waves above 7.5 m occur there naturally every 15 years. Tsunamis are not unusual events. When I was in Japan recently, I discovered that they are a favorite theme in Japanese art, especially in woodblock prints. The earthquake that recently occurred in the Indian Ocean was unusually strong (9.0 on the Richter Scale) and the resulting tsunami resulted in horrific loss of life and property in countries like Indonesia, India, and Sri Lanka. Television has enabled everyone to witness the devastation and its aftermath. More than 150,000 people have died and huge coastal areas have been destroyed. Stunned local populations are responding to an enormous outpouring of international relief aid. What will be the aftermath of this devastating tsunami? Reefs have been damaged or destroyed as have coastal mangrove areas and estuaries. What effects this will have on fish populations and reproduction are unknown. Ponds used to cultivate shrimp have been destroyed. Few fishing boats are left to harvest what fish may be left. Seawater was driven inland, killing plants and animals, and infiltrating agricultural land and wells used for drinking water. The long-term effects on agriculture and well water are not known. Ecologists have an opportunity to study recolonization of affected areas by plants and animals. Epidemics of diseases have not developed as prompt burial of bodies and distribution of clean water and
