Some examples of these hazards include habitat loss, pollution, and invasive species.
More than 50% of wetlands in the U.S. have been destroyed in just the last 200 years. [8] Between 60% and 70% of European wetlands have been completely destroyed. [ 13 ] In the United Kingdom, there has been an increase in demand for coastal housing and tourism which has caused a decline in marine habitats over the last 60 years.
Wetland habitats contribute to environmental health and biodiversity. [60] Wetlands are a nonrenewable resource on a human timescale and in some environments cannot ever be renewed. [61] 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. [61]

Environmental threats to rivers include loss of water, dams, chemical pollution and introduced species. [14] A dam produces negative effects that continue down the watershed. The most important negative effects are the reduction of spring flooding, which damages wetlands, and the retention of sediment, which leads to the loss of deltaic ...
