A few disagreed, such as Captain John Sprague, who wrote he "never supposed the country would excite an inquiry, other than as a hiding place for Indians, and had it occurred to me that so great an undertaking, one so utterly impracticable, as draining the Ever Glades was to be discussed, I should not have destroyed the scratch of pen upon a ...
A portion of the C-38 canal, finished in 1971, now backfilled to restore the Kissimmee River floodplain to a more natural state. An ongoing effort to remedy damage inflicted during the 20th century on the Everglades, a region of tropical wetlands in southern Florida, is the most expensive and comprehensive environmental repair attempt in history.
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.
Some wetlands are a significant source of methane emissions [6] [7] and some are also emitters of nitrous oxide. [8] [9] Nitrous oxide is a greenhouse gas with a global warming potential 300 times that of carbon dioxide and is the dominant ozone-depleting substance emitted in the 21st century. [10] Wetlands can also act as a sink for greenhouse ...
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.
No wetlands excluded, in which wetlands were not omitted from federal protections for being too dry: Between 8 and 19% of NC wetlands lose protection, ranging from 285,200 to 676,7000 acres.
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] However, from 1998 to 2004 the United States managed a net gain of 191,750 acres (776.0 km 2) of wetlands (mostly freshwater). [2] The past several decades have seen an increasing number of laws and ...
Water pollution due to dairy farming in the Wairarapa in New Zealand. Agriculture is dependent on available soil moisture, which is directly affected by climate dynamics, with precipitation being the input in this system and various processes being the output, such as evapotranspiration, surface runoff, drainage, and percolation into groundwater.
