During the disruption, trade winds weaken over the central Pacific Ocean,
resulting in a dramatic rise in the ocean temperatures and a depression of
the thermocline in the pacific. The thermocline is the layer of water
between the warmer, surface zone and the colder deep water zone, in a
thermally stratied body of water, in which the temperature decreases
rapidly with depth.
This depression of the thermocline has great effects on the worlds fishing
industry. The cutting of nutrient rich therocline water reduces the growth
of algae, which in trun, collapses the food chain. Thus, leaving our
worlds subsistence and commercial fisher .....

Black Holes
<view this essay>.... Before the discovery of this black hole, astronomers did not think that there was any dust in elliptical galaxies like NGC 4261. Currently they believe that the disk of dust is the remnant of a smaller galaxy that fell into the core of NGC 4261. The black hole will swallow up the gas from the smaller galaxy over the next 100 million years. Researchers believe that while the gas is being swallowed by the black hole, the process will produce some amazing fireworks.
The second puzzling question that astronomers are trying to answer is why isn't the black hole at the center of the galaxy? According to images from the Hubble Space Telescope, the black hole is 2 .....

Fire 2
<view this essay>.... The introduction of a policy of deliberate burning as a management tool has a fascinating history, especially in the United States Forest Service, but the ecological effects of prescribing a fixed burning regime on large tracts of land are increasingly being questioned (Lyons, 1985, 3).
To an ecologist, fire can be treated as just one of the many factors in an environment. It compares with droughts, floods, hurricanes and other physical disturbances because of the direct impact it makes on organisms. Unlike these physical factors, however, fire as a disturbing force is itself influenced by the biota, particularly the plant community. Alteration of the veg .....

as great a world for our children as it was for us.
First, we need to understand that the oceans are not the vast resources
that we believe them to be, but just vulnerable natural resources. Before
Columbus' day, the ocean were thought to be boundless. Although Columbus proved
this theory incorrect, the thought still remains in today's societies. “For we
of the 20th century still treat the ocean as the endless, bottomless pit it was
considered to be in medieval times.”(Heyerdahl) The majority of the world's
population still lives under the misconception that the ocean is a hungry abyss,
eager to devour all .....
