Many natural events that we think of as “disasters” do not cause widespread ecological devastation.: Many natural events that we think of as “disasters” do not cause widespread ecological devastation. Tsunami Caused Ecological Impacts: According to a recent report, among critical coastal habitats in Aceh & North Sumatra, damage included: 25,000 hectares of mangroves 30% of 97,250 hectares of coral reefs 20% of 600 hectares of seagrass beds were damaged. Respective estimates of economic losses were $118.2 million, $332.4 million, & $2.3 million. Ecological stewardship can buffer against both ecological disasters & natural disasters that impact human populations.

In areas where mangroves have been removed, coastlines have rapidly eroded. Areas where mangroves were intact suffered remarkably few casualties: the forests acted as a living buffer. Villages were saved on the coast of Indonesia's Aceh province. Only 4 people died on Simeuleu Island (30 miles from epicentre of earthquake that caused the tsunami). From Re-active to Pro-active: LEARNING OpportunitiesMangroves planted to act as buffer against sea: Mangroves planted to act as buffer against sea Governments of countries worst hit by the recent tsunami announced plans to plant mangrove forests along their coasts, after being convinced they save lives. The Indonesian forestry minister pledged to restore 1.5 million acres of mangroves. Malaysia 's Prime Minister, called for its mangroves to remain untouched. Thailand is to complete its rehabilitation plan this week. Sri Lanka is trying to ban mangrove destruction. In India, an official commission said it should plant a "bioshield" of vegetation along its coasts. Actions may revitalize fisheries around the Indian Ocean.

Wilson, 2002 “The great dilemma of environmental reasoning stems from this conflict between short-term & long-term values. … To combine the two visions to create a universal environmental ethic is… very difficult. But combine them we must, because a universal environmental ethic is the only guide by which humanity & the rest of life can be safely conducted through the bottleneck into which our species has foolishly blundered.”Differences between “Easy Disasters” & “Difficult Disasters”: Differences between “Easy Disasters” & “Difficult Disasters” Easy: local, a single short-lived stressor, resources from periphery ample to support recovery, public engaged. Difficult: wide area, multiple long-lived stressors, resources from periphery insufficient to support recovery, public disengaged.

US Coral Reefs: Status & Impacts: US Coral Reefs: Status & Impacts According to US Coral Reef Task Force, “2/3 of world’s coral reefs may be dying, & if current conditions continue, 70% may be gone by 2050.” In the 1970s, reefs of Florida Keys contained more than 70% coral. Now, 84% of these reefs are dominated by algae & seaweed. Impacts of reef loss include island subsidence, flooding, reductions in coastal biodiversity – harvest, tourism, & costs of repair.Slide25: NRC’s “Clean Coastal Waters” report proposed a 20 year plan to reduce US marine pollution by 10% by 2010 & 25% by 2020.

Control exotic & invasive species introductions; eliminate exotic species when possible & desirable. Control emerging & re-emerging diseases by facilitating natural disease control: biodiversity, less crowding, stress, more distance from humans. Practice agriculture & forestry that build soil, & do not deplete aquifers or water bodies. Rehabilitate/restore rivers, estuaries, coasts. Harvest animals only at rates that allow recovery of robust, genetically diverse stocks. Restoring Resilience to Ecosystems to Prevent Ecological DisastersRestoring Resilience to Ecosystems to Prevent Ecological Disasters: Getting public support to get business incentives right to: Re-establish connectivity of natural landscapes especially along streams, across uplands. Maintain natural areas large enough to sustain larger native carnivores & other species with large ranges. Provide ample buffers with native plants, & animals—to offset effects of human activities. Maintain areas devoted to human activities in small & large islands linked with one another with transport systems that allow wildlife to migrate & interbreed. Re-establish margins of safety for wildlife resources by enabling their continued evolution.
