What the U.S. Has done, What Is It Doing, and What Needs to Be Done for Environmental
Sustainability
Since the modern environmental movement in the 1960s, the U.S. has been improved its air
and water quality with environmental laws and regulations. Since 1970, the U.S. has spent more
money on environmental protection than any other nation.I Manufacturing companies added
environmental compliance departments to avoid running afoul of environmental laws and
regulation and reduce pollution, energy consumption, and waste by altering their product and
manufacturing process. Social media deliberately informed environmental impacts from
extracting common natural resources over their carrying capacities around the world through
newspapers and internet. Demands of living and working in safe, healthy and attractive places
with sustainable water supplies and air quality were increased. Recently, American households
recycled more wastes, consumed less water, and bought more local products. However, the
U.S. still has a long way to go for environmental sustainability because sustainable
environments depend on the continuous efforts of businesses, governments, and households
to improve and protect damaged environments from Laissez-faire.1 Laissez-faire is a French
phrase which can be translated as “let it do” in English and it refers the economic system or
social engineering that was free from government interferences such
as regulations, privileges, tariffs, and subsidies in the 19th century and it is the one of major
factors of the industrial revolution.II
Major environmental issues such as conserving water supplies, mitigating natural hazards,
retaining forests and farms in sustainable ways, and protecting wildlife habitats require more
than twenty years with current technology to be effectively managed in terms of quality and
quantity, but the usual comprehensive planning process has 10 to 20 years of time horizon. The
regional government in Portland, Oregon recognized the need for long-term planning and
adopted a comprehensive plan that has 45 years of time horizon in 1995.1 What else the U.S.
has done, what is it doing, and what needs to be done for environmental sustainability?
The concerned scholars, citizens, government officials formed offices of sustainability in cities
and universities. More than 1,700 land trusts were formed. Land trusts are non-profit
organizations that actively work to conserve lands and resources. They created their own green
comprehensive plans, climate action plans, green infrastructure plans, and sustainability plans
with excessive geographic information and analyses from geographic information system (GIS)
and light detection and ranging (LIDAR) remote sensing technology. These technologies allowed
planners, developers, local officials, and the public to reason where development should be
done and constrained by identifying physical and cultural landscape features and approximate
amount of natural resources. Recently, 50 million acres of land for wildlife habitat, recreation,
farming, and forestry are preserved.III Some states became more proactive than the federal
government. California’s motor vehicle and air-quality standards are stricter than the federal
standards. Pennsylvania pioneered a brownfields cleanup. Oregon has stringent agricultural and
timber land zoning with urban growth boundaries.1 The federal government did not enforced to
have a certain amount of electricity from renewable sources. Voluntarily, some states adopted
renewable portfolio standards which require utilities to have a certain amount of electricity

from renewable sources.IV Public participation and activism were increased by social media,
land trusts, governments, and technology. The 1990 Amendments to the Clean Air Act were
partially written by representatives from non-profit organizations such as the Natural Resources
Defense Council (NRDC), the Environmental Defense Fund, the Sierra Club, the National Wildlife
Federation, and the National Audubon Society.V Sometimes, non-profit organizations regulate
governments. The Natural Resources Defense Council (NRDC) sued the Environmental
Protection Agency (EPA) to require states to undertake the cleanup of polluted waters through
the Total Maximum Daily Loads (TMDLs) process under the 1972 Clean Water Act.
The U.S. voters approved more than $50 billion for land conservation from 1998 to 2010.VI In
New Jersey, more than 200 municipalities and 23 counties drafted open space plans and
established open space trust funds to buy lands.VII With the investments on nature conservation
and green infrastructures, states, countries, and communities across America are buying private
working landscapes and natural areas and building green infrastructures in order to improve
water quality, storm water and sewer management, wildlife habitat, perpetuate healthy
forests, scenic vistas from public areas, and sustainable agriculture.VIII The U.S. Environmental
Protection Agency (EPA) estimated that the economic benefits of the 1990 Clean Air Act
exceeded the costs more than twelve times in 2010. Increasing awareness of green structures’
benefits even allowed local governments to require green infrastructures in development
projects and give incentives for green roofs, rain gardens, and swales.1 A green roof is a roof
that covered with plants in order to absorb rainwater, provide insulation, create a habitat for
wildlife, lower urban air temperatures, and mitigate the heat island effect.IX A rain garden is a
garden positioned near a downspout, driveway or sump pump to capture rainwater runoff and
stop the water from reaching the sewer system.X A swale is a moist or marshy low tract of land
that designed to manage water runoff, filter pollutants, and increase rainwater infiltration.XI
Contrary, some technologies are not leading the U.S. to more sustainable environments. The
U.S. congress spent approximately $1 trillion dollars on new highway construction and road and
bridge repairs between 1991 and 2012. New highways promoted suburban developments into
the countryside and more vehicle travels.1 Carbon dioxide emission from motorized vehicles
accelerated glaciers melting. Also, carbon Dioxide dissolves calciumcarbonate which is the one
of substances in the shells and skeletons of aquatic organisms and fishes, one of major food
sources in the U.S., are in danger of collapse. More than one-quarter of World’s coral reefs
have been destroyed and 6 of the 10 largest marine ecosystems were being fished at
unsustainable rates.XII Sea water level was increased 3.2 mm in 2013 and climate scientists are
predicting that the sea level can be 7 feet higher by 2100 if mankind does not reduce its
greenhouse gas emission.XIII The Intergovernmental Panel on Climate Change, the world body
for assessing the science related to climate change, ranked coastal flooding death as one of the
major threats and approximately 40% of U.S. population is living on coastal areas.XIV According
to the World Health Organization, floods can kill or traumatize living organisms by
drowning. Also, they can increase water-borne or vector-borne communicable disease
infection by serving breeding sites for infectious disease causing mosquitos, contaminating
drinking water facilities, and spreading rodents’ urine in the soil. The rodents are mammals
that have leptospires, infectious bacterial disease causing pathogens, in their urine. They

urinate on the ground and floods spread those pathogens. This transmission is the only
water-borne epidemic-prone infection which transmits pathogens directly from
contaminated water. Transmission occurs through contact of the skin and mucous
membranes with water, wet soil, and plants. Major water-borne diseases that related
flooding are typhoid fever, cholera, leptospirosis and hepatitis A. Major Vector-borne diseases
that related flooding are malaria, dengue and dengue haemorrhagic fever, yellow fever, and
West Nile Fever.XV Therefore, mitigating greenhouse emission by using more sustainable energy
sources and finding ways to accelerate dispersed carbon dioxide’s absorbing process is crucial
for public health.
What are other disadvantages of constructing more highways? Highways have been blocked
wildlife animals’ natural paths and caused massive damages on vehicles and endangered animal
species. Vehicle-animals collisions costs about $8 Billion per year and about a million animals
die by motor vehicles per day in the U.S. 21 endangered species are in risk of extinction by road
kills. They are: key deer, bighorn sheep, ocelot, red wolves, desert tortoises, American
crocodiles, and Florida panthers.XVI Wildlife crossing structures have been built in the past 30
years. These have been used to protect mountain goats in Montana, spotted salamanders in
Massachusetts, bighorn sheep in Colorado, desert tortoises in California, and endangered
Florida panthers in Florida.XVII However, the U.S. is still spending about $8 billion per year for
animal collisions on highways. 25 state departments of transportations reported that
construction of wildlife crossings range from $1 million to $8.5 million. The average cost is $2.3
million.XVIII With $2 billion, U.S. can build about 200 wildlife crossing structures and the
problems of road kills can be eliminated within a generation.XIX However, the U.S. cannot just
keep building more and more highways and wildlife crossings. Petroleum is not going to last
forever and petroleum demands surpassed the supply.XX In order to deal with air quality,
substantial population growth and increasing traffic congestion in sustainable way, light-rail
systems need to be implemented on metropolitan areas. Portland, Oregon successfully
promoted light rail system. San Diego, California adopted a law which links land-use planning,
transportation, and the reduction of greenhouse gas emission and made a regional plan based
on that law in order to accommodate up to 1 million additional residents.1
Even though the U.S. has spent more money on environmental protection than any other
nation since 1970, it is the second largest greenhouse gas contributor for current climate
change. The investment on green infrastructures, mass transits, and smart growth for
minimizing negative impacts of climate change has fallen well short of the target after the
subprime mortgage crisis according to Bloomberg New Energy Finance.XXI Human health and
well-being are both dependent on ecosystems and are important outcomes of ecosystem
management.XXII We should raise the fund to protect foods, water supplies, lands, plants,
wildlife, and humanity with careful planning, regulation, diligence, and trusts.
