Scenario:World-wide, wetlands provide important resources in terms of water resources, food and building resources, nutrient cycling, and climate controls. Despite their many values, wetlands historically have been misunderstood and abused because their importance wasn't obvious and their hazards, such as malaria and predators, were thought to outweigh the benefits of the wetland. For many years, wetlands were seen as "useless swamps" and were frequently filled, drained, polluted or used for dumping grounds. Many cities, such as Houston, TX, and Foster City, CA were built on former wetlands. Raised and drained former wetlands, especially those in Ohio, Indiana, Illinois, and Iowa provide fertile soils for farming. The destruction of wetlands in the United States alone has been significant - more than half of all wetlands in the 48 contiguous states have been lost since the mid-1700s. In the last twenty years, wetland conservation and restoration efforts have gained steam and fewer wetlands have been negatively impacted and many others have been restored.
