North American desert flora

Near the Colorado River, riparian vegetation and sandy beaches. Just above the river corridor a desert scrub community exists complete with a wide variety of cacti and warm desert scrub species. A pinyon pine and juniper forest grows above the desert scrub up to 6,200 feet, while between 6,200 feet and 8,200 feet ponderosa pine strive. On the North Rim at elevations above 8,200 feet, a spruce-fir forest tops out the park. As in all natural habitats, the type and abundance

Aldo Leopold pioneered “land ethics” in the first half of the 20th century. Inspired by Leopold, his fellow professor at the University of Wisconsin, Van Rensselaer Potter, coined the term “bioethics” in the second half of the 20th century (1970). Both terms have a powerful social and personal component. Both terms connote an integration of values and the environment. So, too, do “hunt ethics,” an integration of values and an action based upon biology and the ‘land.’ The hunter has affection and

Reading Material: Realms of the Earth Astro-physicists and scientists believe that there could be quite a few planets in the Universe similar to our planet Earth. There is also a probable chance that some form of life prevails and sustains in one of such planet. However, so far as we presently know, the Earth is the only planet which supports life which makes it a very unique planet. It is therefore imperative (very important and necessary) for us to understand the spheres of the Earth as the spheres

Park in 1933 under President Franklin Delano Roosevelt, Death Valley is the largest national park in the continental United States even though its total length is no more than approximately 100 miles in length. The valley is located in the Mojave Desert in eastern California and is surrounded by the Amargosa Range on the east, the Panamint Range on the west, and the Sylvania Mountains and Owlshead Mountains on the northern and southern boundaries. The topography of this region is varied and complex;

glaciers have risen from 0.35 mm to 0.4 mm. Scientists have warned in their reports that most of the glaciers will disappear within a period of 15 to 25 years. ("Science News )It will create problems of drinking water and food grains in most of the North American countries. India is not unaffected from it. The Himalayan glaciers have shrunk about 30 per cent after 1970. The rise in sea levels is a major cause of concern. A large number of cities located in coastal areas will submerge in the sea. Besides

It is a major attraction in the park, especially in late spring when the water flow is at its peak. The total 2425-foot

Guns, Germs, and Steel: The Fates of Human Societies, by Jared Diamond, attempts to explain why history progressed differently for people from various geographical regions. Diamond introduces his book by pointing out that history followed different courses for different people because of differences among peoples’ environments, not because of biological differences among people themselves. Through his convincing explanation for how civilizations were created and evolved throughout the course of history

The crack of gunfire and the disruptive shouts of the men ripple through the humid, sweltering air, disturbing the once calm atmosphere that had settled over the Sahel desert of Mali in North Africa. The distinct sound of an ear curdling shriek comes next, followed by a distant thump as a large, limp body crashes to the ground. Just in that moment, another endangered animal is slain out of season by the same faceless men that will be back soon for more. Disturbingly enough, sounds like these and

Global warming is the greatest challenge facing our planet. It is, in fact, the increase in the temperature of the earth’s neon- surface air. It is one of the most current and widely discussed factors. It has far-reaching impact on biodiversity and climatic conditions of the planet. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels, the melting of ice caps and significant worldwide climate changes. In short, global warming represents a fundamental
