When the storm occurs, people are asked to restrict their outdoor activities so they will breathe in the polluted air. The magnitude of impact is directly connected with the intensity of the storm. The more severe ones can cause problems for people going to work and hence can disrupt economic activities. Some of the respiratory problems caused by the YDS can be severe enough to prove fatal. It has been noticed that in areas that encounter yellow dust storms annually, there is an increase in mortality rate.
The effect on farm land is also serious in nature. While the dust itself doesn't harm the farm activities, it is the sulphuric emission and acid rain resulting from the storm that destroy crop by damaging the soil. When soil is affected, animal life is also seriously harmed by the storms especially the cattle. But the effect on sea life is even graver. The economic effects are also especially troublesome as hundreds of flights are cancelled, construction is stopped, manufacturing faces obstacles and general delays crop up in every economic area. (Ai, 2003)
To help us gauge the possible effects of YDS, researches Guo and his colleagues (2005) cite examples of two storm cases and resulting destruction: "a YDS occurred in 1993 in Gansu Province, China directly affected area of 1.1 million square kilometers, caused 85 deaths and 246 injuries, destroyed 4,412 houses, killed 120,000 livestock, and damaged 373,000 hectares of crops land. The direct economic cost of the YDS alone was estimated to be more than 550 million RMB, or about $66 million at current...
For example, the soil in the Loess Plateau area is notoriously erodable and it is difficult to revegetate the steep slopes with a sufficiently dense cover of plantation and grass. Moreover, rainfall in the area is generally insufficient to support the growth of trees and plants even after their plantation; grazing by animals worsens the situation. Silt retention dams and structures in the silt-carrying gullies and valleys have proven
European Epidemics on Native American Lifestyles When the Europeans arrived in America, the Native Americans were a settled agricultural people. These Indians relied heavily on corn, beans and squash and their diet was supplemented through the gathering of wild plants and hunting. (Geier, 1991) Hundreds of thousands of Native Americans lived in America with the greatest diversity - as many as 120 - of languages, dialects, and cultures of any comparably

ecosystem, which is a biological environment made up of various organisms, whether living or not, physical constituents which life forms interact with, for example, soil, water, and sunlight. Environmental homeostasis is achieved with the presence of various insects and critters in the ecosystem. This paper will delve into the role wasps' play as biological pest control, nesting habits, and various methods to control the population. A majority of wasps are
Richard Hughes: A High Wind in Jamaica This story, the first novel by Richard Hughes, takes place in the 19th Century, and mixes the diverse subjects of humor, irony, satire, pirates, sexuality and children into a very interesting tale, with many sidebar stories tucked into the main theme. The first part of the story has an eerily familiar ring and meteorological link with the December, 2004 tsunami-related disaster in Asia. In A
Even though users of light therapy are often advised not to look directly at the light source, the mechanisms of the eye focus incoming light onto the macula, the small region of the retina where vision takes place, and where age-related macular degeneration occurs. Since blue light wavelength make up only a small percentage of the light in white light, any form of light therapy using a high proportion
