'We begin with Maryland’s extraordinarily rich native flora (that is, the set of all its native plants), and the geologic and historic forces that shaped it. Maryland’s flora includes about 2500 species. Yet, 710 of those species, or about 28%, are now listed as rare, threatened, endangered or extinct in Maryland by the Wildlife and Heritage Service of the Department of Natural Resources. Rare, threatened and endangered species are like the "canary in the coal mine." Their status is an indicator of the health of the ecosystems that we share with them, and can signal the decline of animals and other plants whose existence may not yet be threatened.'

10 Things They Won’t Tell You About the Flint Water Tragedy. But I Will. / : Michael Moore.
- http://michaelmoore.com/10FactsOnFlint/
'News of the poisoned water crisis in Flint has reached a wide audience around the world. The basics are now known: the Republican governor, Rick Snyder, nullified the free elections in Flint, deposed the mayor and city council, then appointed his own man to run the city. To save money, they decided to unhook the people of Flint from their fresh water drinking source, Lake Huron, and instead, make the public drink from the toxic Flint River. When the governor’s office discovered just how toxic the water was, they decided to keep quiet about it and covered up the extent of the damage being done to Flint’s residents, most notably the lead affecting the children, causing irreversible and permanent brain damage. Citizen activists uncovered these actions, and the governor now faces growing cries to resign or be arrested.'

Beneath the murky green waters on the north end of Lake Powell, entombed within the tons of silt that have been carried down the Colorado River over the years, lies a 26,000-ton pile of un-remediated uranium mill tailings. It's just one polonium-, bismuth-, thorium-, and radium-tainted reminder of the way the uranium industry, enabled by the federal government, ravaged the West and its people for decades.

The Louisiana Gulf Coast is experiencing the highest rates of coastal erosion and wetland loss in the U.S. The average coastal erosion rate is 4.2 meters per year in Louisiana and 1.8 meters per year along the northern Gulf of Mexico shoreline. However, the most serious erosion and land loss is occurring in the eastern part of the coastal area, east of Atchafalaya Bay.
Jankowski, K. L. et al. Vulnerability of Louisiana’s coastal wetlands to present-day rates of relative sea-level rise. Nat. Commun. 8, 2017.
Coastal wetlands provide exceptionally valuable ecosystem services, including wildlife habitat, food production, biogeochemical cycling and storm-related disturbance regulation. Globally, 64–71% of wetlands (including coastal wetlands) have been lost since 1900 AD. Louisiana is home to 40% of wetlands in the contiguous United States, yet has suffered 80% of the total wetland loss.

GAO: Abandoned Mines: Information on the Number of Hardrock Mines, Cost of Cleanup, and Value of Financial Assurances. / : Statement of Anu K. Mittal, Director Natural Resources and Environment Team, 2011.
GAO 'issued a number of reports and testimonies on various issues related to abandoned and current hardrock mining operations. This testimony summarizes some of the key findings of these reports and testimonies focusing on the (1) number of abandoned hardrock mines, (2) availability of information collected by federal agencies on general mining activities, (3) amount of funding spent by federal agencies on cleanup of abandoned mines, and (4) value of financial assurances for mining operations on federal land managed by BLM. In 2005, GAO recommended that BLM strengthen the management of its financial assurances, which BLM generally implemented. BLM also agreed to take steps to address additional concerns raised by GAO in 2008'.
'GAO’s past work has shown that there are no definitive estimates of the number of abandoned hardrock mines on federal and other lands. For example, in 2008 and 2009, GAO reported that BLM and the Forest Service had difficulty determining the number of abandoned hardrock mines on their lands and had no definitive estimates. Similarly, estimates of the number of abandoned hardrock mine sites in the 12 western states and Alaska (where most of the mining takes place) varied widely because there was no generally accepted definition of what constitutes an abandoned hardrock mine site. In 2008, GAO developed a standard definition for abandoned hardrock mining sites and used this definition to determine that there were at least 161,000 abandoned hardrock mine sites in the 12 western states and Alaska, and at least 33,000 of these sites had degraded the environment, by contaminating surface water and groundwater or leaving arsenic-contaminated tailings piles.'
GAO: Hazardous waste cleanup : Numbers of Contaminated Federal Sites, Estimated Costs, and EPA’s Oversight Role, 2015
The Departments of Agriculture (USDA), the Interior, Defense (DOD), and Energy (DOE) have identified thousands of contaminated and potentially contaminated sites on land they manage but do not have a complete inventory of sites, in particular, for abandoned mines. GAO reported in January 2015 that USDA had identified 1,491 contaminated sites and many potentially contaminated sites. However, USDA did not have a reliable, centralized site inventory or plans and procedures for completing one, in particular, for abandoned mines. For example, officials at USDA’s Forest Service estimated that there were from 27,000 to 39,000 abandoned mines on its lands—approximately 20 percent of which may pose some level of risk to human health or the environment. GAO also reported that Interior had an inventory of 4,722 sites with confirmed or likely contamination. However, Interior’s Bureau of Land Management had identified over 30,000 abandoned mines that were not yet assessed for contamination, and this inventory was not complete. DOD reported to Congress in June 2014 that it had 38,804 sites in its inventory of sites with contamination. DOE reported that it has 16 sites in 11 states with contamination.

'Four agencies (referred to in this report as the federal land management agencies, or FLMAs) administer a total of 614 million surface acres (95%) of federal lands: the Forest Service (FS) in the Department of Agriculture (USDA), and the Bureau of Land Management (BLM), Fish and Wildlife Service (FWS), and National Park Service (NPS), all in the Department of the Interior (DOI). The federal estate also extends to the energy and mineral resources located below ground and offshore. These include about 700 million onshore acres of the federal subsurface mineral estate that are managed by BLM. In addition, the Bureau of Ocean Energy Management (BOEM), also in DOI, manages approximately 1.7 billion offshore acres located in federal waters within and beyond the U.S. Exclusive Economic Zone. Not all of these acres contain extractable mineral and energy resources.'

CRS: Federal Involvement in Flood Response and Flood Infrastructure Repair: Storm Sandy Recovery. / : Nicole T. Carter. Specialist in Natural Resources Policy. October 31, 2012. - 12 s.
'Although the storm was not notable for its wind intensity, Sandy’s significant size, its unusually low atmospheric pressure, and the astronomic high tide combined with other weather systems to amplify flooding consequences and economic and transportation disruptions. With events like Storm Sandy, common questions for Congress include: Which federal programs can assist with flood-fighting? Which federal programs can assist with repairing damaged dunes, levees, and other flood protection? What are the policy and funding issues that may arise during recovery? While state and local entities have significant flood-related responsi-bilities, federal resources are called in as these entities are overwhelmed and as presidential disasters are declared. Several agencies, including the Federal Emergency Management Agency (FEMA) and the U.S. Army Corps of Engineers, have authorities to respond to flood emergencies and to assist with recovery efforts.'
CRS: Water Resource Issues in the 113th Congress. / : Betsy A. Cody et al. January 31, 2013. - 14 s.
'Federal Water Resource Agencies
Most of the large dams and water diversion structures in the United States were built by, or with the assistance of, Reclamation or the Corps. Historically, Reclamation projects were designed principally to provide reliable supplies of water for irrigation and some municipal and industrial uses. Corps projects were planned principally to improve navigation and reduce flood damages, with power generation, water supply, and recreation being incidental benefits. Reclamation currently manages more than 600 dams and reservoirs in 17 western states, providing water to approximately 10 million acres of farmland and 31 million people, as well as 58 power plants capable of producing 40 billion kilowatt-hours of electricity annually (enough for approximately 3.5 million homes). The Corps operates nationwide, and its activities are diverse. The Corps has constructed thousands of flood damage reduction and navigation projects throughout the country, including nearly 12,000 miles of commercially active waterways, nearly 1,000 harbors, and 600 dam and reservoir projects (with 75 hydroelectric plants generating 68 billion kilowatt-hours annually). Additionally, the Corps constructed, usually with nonfederal participation, roughly 9,000 miles of the estimated 100,000 miles of the nation’s levees, but only maintains 900 miles. The remaining levees are operated by nonfederal entities, often local governments or special districts.'

Greenhouse effect, sea level rise, and coastal wetlands. / : James G Titus et al.
- Washington, D.C. : U.S. Environmental Protection Agency, 1988. - 168 s.
- http://archive.org/details/greenhouseeffect00titu
'Increasing atmospheric concentrations of carbon dioxide and other gases released by human activities are generally expected to warm the earth a few degrees (C) in the next century by a mechanism commonly known as the "greenhouse effect." Such a warming could raise sea level by expanding ocean water, melting mountain glaciers, and eventually causing polar ice sheets to slide into the oceans. Unfortunately, it is not yet possible to accurately predict future sea level. Estimates for the year 2025 range from five to fifteen inches above current sea level, while estimates of the rise by 2100 range from two to seven feet. Although the timing and magnitude of future sea level rise is uncertain, there is an emerging scientific consensus that a significant rise is likely.
To further society's understanding of how to rationally respond to the possibility of a substantial rise in sea level, EPA has undertaken assessments of the impacts of sea level rise on economic development, beach erosion control strategies, salinity of estuaries and aquifers, and coastal drainage and sewage systems. Those studies have generally found that even a one-foot rise in sea level has important implications for the planning and design of coastal facilities. This report examines the potential impacts of sea level rise on coastal wetlands in the United States. Coastal marshes and swamps are generally within a few feet of sea level, and hence could be lost if sea level rises significantly. Although new wetlands could form where new areas are flooded, this cannot happen where the land adjacent to today's wetlands is developed and protected from the rising sea. Once built, neighborhoods can be expected to last a century or longer. Therefore, today's coastal development could limit the ability of coastal wetlands to survive sea level rise in the next century.'

The northern Great Plains of Canada and the United States cover thousands of square miles. This true-color Aqua MODIS image from May 3, 2005, shows a portion of the Great Plains covering Saskatchewan, Manitoba, and a small slice of Ontario, Canada, and Montana, North Dakota, Minnesota, Wyoming, and South Dakota in the United States. Scattered across the region are thousands of lakes ranging in color from deep blue-green and black to milky blue, tan, and even white. In the northern part of the image, many of the lakes are white because their surfaces are still frozen from the cold winter, and spring temperatures have not risen enough to thaw them completely. The largest lake in the scene, Lake Winnipeg, shows the greatest amount of surface ice, while the clear water at its northern end shows swirls of milky tan sediment. To the east, Lake Manitoba is ice free, but also shows swirls of cloudy sediment in its waters. - http://archive.org/details/VE-IMG-8088
