New studies from North Carolina State University suggest
that Native Americans from the Cherokee tribe during the Trail of Tears in the
1830’s experienced an interference with the normal growth of their skulls due to extreme
amounts of stress. Stress affects
cranial length, and this affect decreases the size of the skull. Data collected
of adults born between 1783 and 1874 shows a significant truncation of the
skull. The leader of the study, Ann H. Ross, says that this type of research
allows scientists to interpret the effects of historical events.

White House Unveils Plans to Cut Methane Emissions
President Obama and his administration have announced a new
plan in which methane emissions will be significantly reduced. This plan is
another part of what the White House plans to build to take action toward reducing
climate change problems. Methane in the
United States has been increasing in recent years mainly though hydraulic fracturing
and this gas can lead to more entrapment of infrared energy in Earth. The EPA and
the white house will work together on this plan by updating standards and
making them stricter. The EPA believes that these plans will be completed by 2016,
right before President Obama will leave office.

Pollution and Dust in Britain Bring Health Warnings
In London, high levels of air pollution were reported in
parts of England, which made the government enact smog alerts and health warnings
for elderly and people with heart of lung problems. The French last month had
seen similar problems of air pollution and the government had responded by
imposing partial driving bans and offering free mass transit for several days.
Environmentalists have used these incidents to emphasize the problems of
pollution cannot be avoided, but rather fixed immediately.

After Fires at Golf Courses, Study Suggests Unusual Culprits: Titanium Clubs
Recent studies by researchers at the University of
California, Irvine have shown that titanium golf clubs, when striking a rock, can
create sparks hot enough to start a brush fire. In California, there have been
two recent golf course fires, and although they have been originally thought to
be caused by cigarettes or cigars, were concluded that both incidents involved
3-irons with titanium alloy heads striking the ground and creating sparks that
caused the fire. Thus, it was concluded that people should not hit from these
areas if they do not wish to burn down a golf course.

Questions as More Wastewater Flows in North Carolina
Duke Energy, a power holding company based in North
Carolina that is under federal investigation for unlawfully spilling toxic
waste into the Dan River in N.C., has just released wastewater last week from
a second site that is thought to be an illegal act by state regulators. These state
regulators have claimed that Duke Energy has violated water pollution laws in 6
different sites by spilling coal ash, from burning coal that makes electricity,
into the water. Although critics have claimed that the company has “an overly
cozy relationship with state regulators,” the state environmental agency has
responded by calling for tougher regulations of coal ash. In response to this,
Duke Energy has said this month that it will move coal ash from several sites
away from public water, and will remove water from ash ponds within 24-36 months.

After Fukushima, Utilities Prepare for Worst
At the Peach Bottom Nuclear Plant in Pennsylvania, engineers and technicians
have been taking precautions and preparing for scenarios that could possibly occur and create major world problems. Three years after the Fukushima disaster, power plants, such as Peach Bottom, have learned from this tragedy to take precautions. New pumps, connections, and multiple emergency back-up plans will be installed to defend and
address nearly every possible scenario that could happen at these sites.
Unfortunately, remodeling these power plants costs somewhere between 400 to 500 million dollars, a costly amount of money, and leads the public to question whether nuclear energy is really the ideal
source of energy for the future. Thus, while it is important to sanction safety regulations for nuclear plants, I believe a greater importance should be placed on research for a more efficient form of energy.

Caribbean Islands Agree to Swap Diesel Power for Renewable Sources
Several Caribbean counties, including St. Lucia, Turks,
Caicos, and the British Virgin Islands, have committed to producing energy
through renewable sources over the current mode of diesel generators. Such
renewable sources include wind, solar, or geothermal energy. According to
Richard Branson, the Caribbean Islands have always paid extremely high
electricity costs, and this renewable push will not only reduce them sharply,
but help improve the quality of the region by producing cleaner energy. While
experts say that the need to create renewable energy is still too expensive for
the continental United States, but will strive to promote change when costs
become more pragmatic.

Coal Makes A Comeback Despite Natural Gas Abundance
Although America acclaims there is a positive transition
towards natural gas, this year’s winter, the coldest in 30 years, has made
Americans divert back to coal. This is primarily because the cold winter had
made natural gas prices its highest level in four years, and coal's prices were more economically feasible. The sudden increase in
cheap coal has led to US carbon emissions that are projected to rise after
successfully decreasing emissions in both 2011 and 2012. While we continue to
struggle to find ways to balance improving our environment without putting a
toll on our economy, we look toward a better future of attaining a renewable
resource world.

Germany Plans to Raze Towns for Brown Coal and Cheap Energy
The world is at a serious risk as Germany, who is looked
upon as the lead engineer for renewable energy, is relocating villages to
create massive strip mines where they can extract Brown Coal for energy. Brown
Coal was used as early as 1934 and lasted until the end of the Cold War, and
has the lowest grade of coal with the highest carbon dioxide emissions per
kilowatt-hour produced. Now, Germany is pushing to have 80% of power as
renewable energy by 2050 using subsidies such as solar and wind power, which
make up roughly 25% of their electric power today (US is 12%). Experts believe Brown Coal mining is being used now because Germany’s energy revolution pursuit might not be going as planned, and there
may be more coal needed to supply the demands. For example, Germany’s nuclear
power industry will be shut down by 2022, and this decision was announced in
2002, but not fully agreed on until after the Fukushima disaster in 2011. Although
natural gas produces lower carbon dioxide emissions, through an economic
standpoint, it is not feasible for Germany to use this because Brown Coal is
significantly cheaper. However, it is estimated that Brown Coal supplies may
run out in 10-15 years. Thus, it is essential for Germany and other countries
to research for alternative renewable energy that will no longer harm to environment.

Severe Drought Has U.S. West Fearing Worst
According to Ingram, a professor of earth and planetary sciences
at Berkeley, California’s severe drought looks to be the worst drought the
region has experienced in over 500 years. It is predicted that about
forty-thousand people will run out of water within 60 to 120 days. If
conditions continue to stay dry, state officials say they will bring trucks of
drinking water to supply communities. These arid conditions have caused parched
fields, starving livestock, and smog. While Western America has been known
to lack water, officials continue to search for answers to supply water to
inhabitants and farm fields, hoping that rain will soon replenish the land.

Return to Normal in Parts of West Virginia Is Marred by Distrust
In West Virginia, a coal cleaning chemical, MCHM, had contaminated
the water and has forbidden thousands of West Virginians to drink or use any
water. As a result, many have been forced to drink and wash with bottled water.
However, even as the chemical has been diluted enough to be considered safe to
drink, many West Virginians still will not drink the water. Their reasons
primarily include fears of damage to the liver or kidneys, and interference
with human metabolisms. Hopefully with time, the water will be able to dissolve
the chemicals into small enough pieces where the chemicals will have no effect
on humans.

Bracing for Carp in Great Lakes, but Debating Their Presence
According to the Army Corps of Engineers, remnants of environmental
DNA of the Asian carp have been discovered to have arrived in the Great Lakes.
Environmental DNA, or eDNA, is genetic material that is not directly from the
fish, but from shedding of scales, gills, or waste products found from birds
who have consumed this fish. This invasive species was first introduced from
China to clean up algae-ridden fishponds in the Arkansas River in 1976. Since
then, the carp has moved up the Mississippi River towards the Great Lakes. If
these fish make it to the lakes, it can cause large problems. The carp
reproduces very quickly and can eat as much as 10 percent of its own weight in
a day. Thus, these fish can lead to the possibility of wiping out entire ecosystems.
Therefore, environmentalists must act quickly before this non-native species
eliminates the entire region.
