Question # 5
The year 2006 was the golden
anniversary, or the 50th birthday, of the Dwight D. Eisenhower
National System of Interstate and Defense Highways. This system, usually
referred to as The Interstate Highway System, is a system of freeways named
after the U.S. President who supported it. The system is the largest highway
system in the world, consisting of 46,876 miles (75,440 km) of freeways. The
construction of the interstate highway system is an important part of American
history. It has played a major role in preserving and maintaining the America way of life.
The interstate highway system has
several major functions. One of its major functions is to facilitate the distribution of US good. Because the
intestate passes through many downtown areas, it plays an important role in the
distribution of almost all goods in the United States.
Nearly all products travel at least part of the way to their destination on the
Interstate System. Another major function of the interstate is to facilitate
military troop movement to and from airports, seaports, rail terminals and
other military destinations. The Interstate highways are connected to route in
the Strategic Highway Network, which is a system of highways that are vital to the U.S. Department of Defense.
Today, most of the Interstate system
consists of newly constructed highways. The longest section of the Interstate
system runs from Boston, Massachusetts to Seattle, Washington. It covers
3,020.54 miles. The shortest two-digit interstate is from Emery, North Caroline
to Greensboro, North Caroline. It covers only 12.27 miles. All state capitals
except five are served by the system. The five that are not directly served are
Juneau, AK, Dover, DE, Jefferson City, MO, Carson City, NV, and Pierre, SD. The
Interstate Highway System serves almost all major U.S. cities.
EACH Interstate highway is marked
with a red, white, and blue shield with the word “Interstate,” the name of the
state, and the route number. Interstate highways are named with one or
two-digit numbers. North-south highways are designated with odd numbers; east-west highways are
named with even numbers. The north-south Interstate highways begin in the west
with the lowest odd number; the east-west highways begin in the south with the
lowest even numbers. There all mile markers at each mile of the interstate
system, starting at the westernmost or southernmost point on the highway. Every
Interstate highway begins with the number “0”. Interchanges are numbered
according to their location on the highway in relation to mileage; an exit
between milepost 7 and milepost 8 would be designated “Exit 7.” This system
allows drivers estimate the distance to a desired exit, which a road is leading
off the highway. Despite the common acceptance of the numbering system on the
Interstate highways, some states have adopted different numbering systems. For
example, a portion of the Interstate 19 in Arizona is measured in kilometers
instead of miles since the highway goes south to Mexico.
Since the Interstate highways are
freeways-highways that do not have signs and cross streets – they have the
highest speed limits in the nation. Most interstate highways have speed limits
between 65 – 75 miles per hour (105 – 120 kilometers per hour), but some areas
in Texas and Utah have an 80 mile-per-hour (130 kilometer-per-hour) speed
limit.
The federal government primarily
funds interstate highways. However, they are owned and operated by the
individual states or toll authorities in the states. The federal government
generally funds up to 90% of the cost of an Interstate highway, while the
states pay the remainder of the cost.

Question # 6
A great deal of discussion countries as to the real extent
of global environmental degradation and its implicational. What few people
challenge however is that the renewable natural resources of developing
countries are today subject to stresses of unprecedented magnitude. These
pressures are bought about, in part, by increased population and the quest for
an ever expanding food supply. Because the healthy, nutrition and general
well-being of the poor majority are directly depends on the integrity and
productivity of their natural resources, the capability of governments to manage
them effectively over the long term becomes of paramount importance.
Developing countries are becoming more aware of the ways in
which present and future economic development must build upon a sound and
sustainable natural resources base. Some are looking at our long tradition in
environmental protection and are receptive to US assistance which recognizes
the uniqueness of the social and ecological systems in these tropical
countries. Developing countries recognize the need to improve their capability
to analyze issues and their own natural resource management. In February 1981,
for example AID funded a national Academy of Sciences panel to advise Nepal on
their severe natural resource degradation problems. Some countries such as
Senegal, India, Indonesia and Thailand, are now including conservation concerns
in their economic development planning process.
Because so many governments of developing nations have
recognized the importance of these issues, the need today is not merely one of
raising additional consciousness, but for carefully designed and sharply
focused activities aimed at management regimes that are essential to the
achievement of sustained development.
