Mitigation, per the EPA, “refers to the restoration, creation, or enhancement of wetlands to compensate for permitted wetland losses”. The amount of wetlands on planet Earth has been diminishing, according to researchers. Industrialization is the main cause, as wetlands are displaced for structures, roadways, and parking lots. This is a problem, they say, for local ecosystems and for the planet at large. Wetlands are a natural resistance to air and water pollution, drought, and flooding.
