Transportation technology is no exception: the single largest element responsible for the high-output power requirements of internal combustion engines had always been the need to overcome friction. For the same reason, all mechanical means of producing energy for transportation systems also require copious amounts of lubrication, adding another major source of environmental impact from petroleum waste products (Rodrigue, 2010). The physical mechanics of thermal friction also contributes greatly to the

Environmental Science Suburban Sprawl: Problems and Solutions The objective of this work is to discuss the cost and benefits of low density suburban development and to who it is that gains and loses. Low density urban sprawl was seen as the answer to housing the growth urban population in both Australia and USA cities. However, this has proven to be untrue and the facts speak quite differently. Health problems are many in these

LD50 values are not always given on the pesticide label; rather, the relative toxicity of a pesticide product is exposed by one of three signal words: DANGER, WARNING, or CAUTION. The rationale for signal words is to alert the user to the level of toxicity of the product. The signal word is usually assigned based on the pesticide's inhalation, oral or dermal toxicity, whichever is the most toxic" (Lethal

But they must remember the analogy of the 'dust bowl' in America -- exploit the earth now, but pay the price with a barren ocean in the future. Other water

Just sitting there, stop-and-go, slow-and-go, wasted two full weeks of work time per year; and the "excess fuel consumption due to congestion" added up to $1,055 for each resident of the Washington, D.C. area a year. But wait - is the money spent on wasted fuel all the harm that is done? No, in fact, "vehicle exhaust remains a serious problem" in the D.C. area. Vehicles are the "main source
