Some pro-environmentalists, like Sioux medicine man John (Fire) Lame Deer, claim that the damage industrialized society has done to nature is both immense and nearly criminal , the result of greed. Lame Deer complains that the white men "have not only despoiled the earth, the rocks, the minerals, all of which they call ‘dead' but which are very much alive; they have even changed the animals, which are a part of us, part of the Great Spirit, changed them in a horrible way, so no one can recognize them" (Erodes 209).

This took a lot of time researching, as there are so many to choose from. I also wasn't real sure of where to begin. I decided to begin with location and money, which are important when deciding a college. Next I decided to visit the few I singled out which greatly helped me choose this for my education. Next I had to perform and even harder task, choosing a major. It's very difficult to decide what you want to do with the rest of your life in just a short time. I had the plans o .....

The software industry can be split into three broad sectors:
? Small Office, Home Office (SO-HO)
? Games
? Industrial Use
Because of the difficulty in separating consumer software purchased by individuals, into applications destined for use by busi .....

Photoperiodism
<view this essay>.... is the
flowering of plants. The ability to respond to day length is linked to an
inner, light-sensitive circadian rhythm.
In the temperate zones, day lengths during the natural 24-hour cycle
vary with the seasons. In winter and spring, the period of light
lengthens; in summer and autumn, it shortens. Plants in these zones
undergo alternate 12-hour phases of light sensitivity. During one 12-hour
phase, decreasing exposure to light induces a short-day reaction. For
example, deciduous trees under the influence of the shorter days of fall
drop their leaves. During the other 12-hour phase, more exposure to light
creates a long-day reaction. Deciduous trees grow .....

Plate Tectonics
<view this essay>.... Howard Hess and R. Deitz to revive Holmes' convection theory. Hess and Deitz modified the theory considerably and called the new theory "Sea-floor Spreading". Among the seafloor features that supported the sea-floor spreading hypothesis were: mid-oceanic ridges, deep sea trenches, island arcs, geomagnetic patterns, and fault patterns.
Mid-Oceanic Ridges
The mid-oceanic ridges rise 3000 meters from the ocean floor and are more than 2000 kilometers wide surpassing the Himalayas in size. The mapping of the seafloor also revealed that these huge underwater mountain ranges have a deep trench which bisects the length of the ridges and in places is more than 200 .....

Uranium: Nuclear Friend Or Nuclear Foe
<view this essay>.... found uranium in 1789, the study of uranium dates
back much further. As early as the sixteenth century it was recognized that
men who worked in pitchblende( a chemical containing iron ore) mines were
subject to fatal pulmonary diseases. An early study of the Schneeberg mines
of Germany conducted between 1869 and 1877 found that 650 miners working in
the mines had a life expectancy of 20 years after entering the mines.
It was two german doctors, Harting and Hesse, who brought this to
the public. The doctors found that 75 percent of the miner deaths were due
to lung cancer. But with their scientific knowledge the doctors could only
assume that the deaths w .....

Extinction Of Dinosaurs
<view this essay>.... such as plesiosaurs,
mosasaurs, ichthyosaurs, and ammonites, swimming and flying reptiles, sea
crocodiles, and foraminifera. In addition to that there were many bony fish,
sponges, snails, clams, and sea urchins became extinct.
Paleontologists have proposed scenarios that could have caused these
extinctions. One such scenario involves the growing number of small mammals
which ate dinosaur eggs, and therefore caused the dinosaurs' birth rate to drop.
The birth rate became smaller than the death rate and the dinosaurs died out.
This, however, is not a plausible scenario. This would only account for the
dinosaurs, but not all the other creatures of that ti .....
