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.
Some of the developing countries of Asia and Africa have
Arrowheads, which are ancient
hunting tools, are often themselves ‘hunted’ for their interesting value both
as artifacts and as art. Some of the oldest arrowheads in the United States
date back 12,000 years. They are not very difficult to find. You need only to
walk with downcast eyes in a field that has been recently tilled for the spring
planting season, and you might find one.
Arrowheads are tiny stones or pieces
of wood, bone, or metal which have been sharpened in order to create a tipped
weapon used in hunting. The material is honed to an edge, usually in a
triangular fashion, and is brought to a deadly tip. On the edge opposite the
tip is a flared tail. Though designs vary depending on the region, purpose, and
era of the arrowhead’s origin, the tails serve the same purpose. The tail of
the arrowhead is meant to be strapped onto a shaft, which is a straight wooden
piece such as a spear or an arrow. When combined, the arrowhead point and the
shaft become a lethal projectile weapon to be thrown by arm or shot with a bow
at prey.
Indian arrowheads are important
artifacts that give archeologists (scientists who study past human societies)
clues about the lives of Native Americans. By analyzing an arrowhead’s shape,
they can determine the advancement of tool technologies among certain Native
American groups. By determining the origin of the arrowhead material (bone,
rock, wood, or metal), they can trace the patterns of travel and trade of the
hunters. By examine the location of the arrowheads, archeologists can map out
hunting grounds and other social patterns.
Arrowheads are commonly found
along riverbanks or near creek beds because animals drawn to natural water sources
to sustain life were regularly found drinking along the banks. For this reason,
riverbeds were a prime hunting ground for the Native Americans. Now, dry and
active riverbeds are prime hunting grounds for arrowhead collectors.
Indian arrowheads are tiny pieces
of history that fit in the palm of your hand. They are diary entries in the
life of a hunter. They are museum pieces that hide in the dirt. They are
symbolic of the eternal struggle between life and death.
