A large wetland in western Minnesota. Over the past 200 years, the United States has lost more than 50% of its wetlands. [1] And even with the current focus on wetland conservation, the US is losing about 60,000 acres (240 km 2) of wetlands per year (as of 2004). [2]
Wetland habitats contribute to environmental health and biodiversity. [58] Wetlands are a nonrenewable resource on a human timescale and in some environments cannot ever be renewed. [59] Recent studies indicate that global loss of wetlands could be as high as 87% since 1700 AD, with 64% of wetland loss occurring since 1900. [59]
Commonly, wetland loss is defined as the conversion of vegetated wetlands into either uplands or drained areas, unvegetated wetlands (e.g., mudflats), or (submerged habitats (open water). According to this, and similar definitions, wetland loss includes both land loss and land consumption as components of it. In historic times, both wetland and ...
Although the endangered species is protected, habitat loss from human development is a major reason for the loss of green turtle nesting beaches. Wetlands and marine areas have endured high levels of habitat destruction. More than 50% of wetlands in the U.S. have been destroyed in just the last 200 years. [8]

A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
The EPA and Army Corps of Engineers announced a new definition of “waters of the United States” intended broaden protections for wetlands, rivers and tributaries. EPA issues new rule to ...
Urbanization causes overcrowding and increasingly unsanitary living conditions, especially in developing countries, which in turn exposes an increasingly number of people to disease. About 79% of the world's population is in developing countries, which lack access to sanitary water and sewer systems, giving rises to disease and deaths from ...
