Environmental care to the technological impact - Examples

Environmental care to the technological impact - Technology impact

The application of technology (in general) often results in unavoidable environmental impacts, which according to the I=PAT equation is measured as resource use or pollution generated per unit GDP. Environmental impacts caused by the application of technology are often perceived as unavoidable for several reasons. First, given that the purpose of many technologies is to exploit, control, or otherwise “improve” upon nature for the perceived benefit of humanity while at the same time the myriad of processes in nature have been optimized and are continually adjusted by evolution, any disturbance of these natural processes by technology is likely to result in negative environmental consequences. Second, the conservation of mass principle and the first law of thermodynamics dictate that whenever material resources or energy are moved around or manipulated by technology, environmental consequences are inescapable. Third, according to the second law of the thermodinamics, order can be increased within a system (such as the human economy) only by increasing disorder or entropy outside the system (i.e., the environment). Thus, technologies can create “order” in the human economy (i.e., order as manifested in buildings, factories, transportation networks, communication systems, etc.) only at the expense of increasing “disorder” in the environment. According to a number of studies, increased entropy is likely to be correlated to negative environmental impacts.

Environmental care to the technological impact - Environmental impact in China

China is the most populated country in the world whith lot of technological devices, and this causes lot of enviromental problems. Here i have found a video of how technology affect our environment, it explains us the impact of technology in the enviroment, in the case in China.

Environmental care to the technological impact - Women an the enviroment

In the early 1970s an interest in women and their connection with the environment was sparked, largely by a book written by Esther Boserup  entitled, Woman's Role in Economic Development. Starting in the 1980s, policy makers and governments became more mindful of the connection between the environment and gender issues. Changes began to be made regarding natural resource and environmental management with the specific role of women in mind. According to the World Bank in 1991, "Women play an essential role in the management of natural resources, including soil, water, forests and energy...and often have a profound traditional and contemporary knowledge of the natural world around them'". Whereas women were previously neglected or ignored, there was increasing attention paid to the impact of women on the natural environment and, in return, the effects the environment has on the health and well-being of women. The gender-environment relations have valuable ramifications in regard to the understanding of nature between men and women, the management and distribution of resources and responsibilities and the day-to-day life and well being of people

Environmental care to the technological impact - I=PAT

I = PAT is the lettering of a formula put forward to describe the impact of human activity on the environment.

I = P × A × T

In words:

Human Impact (I) on the environment equals the product of P= Population, A= Affluence, T= Technology. This describes how our growing population, affluence, and technology contribute toward our environmental impact, but in this part im going to explain only the technologocal impact on the enviroment.

The T variable in the I=PAT equation represents how resource intensive the production of affluence is; how much environmental impact is involved in creating, transporting and disposing of the goods, services and amenities used. Improvements in efficiency can reduce resource intensiveness, reducing the T multiplier. Since technology can affect environmental impact in many different ways, the unit for T is often tailored for the situation I=PAT is being applied to.

Enviromental impact:

Increases in efficiency can reduce overall environmental impact. However, with P increasing exponentially, T would have to decrease drastically (doubling efficiency each time the population doubles) just to maintain the same impact with the same affluence. Over the last few years, data from the World bank has shown that T has decreased and that it is likely to continue to do so in the future. .

Environmental care to the technological impact - Introduction

INTRODUCTION:

The general public believes that technology will improve health care efficiency, quality, safety, and cost. However, few people consider that these same technologies may also introduce errors and adverse events. Given that nearly 5,000 types of medical devices are used by millions of health care providers around the world, device-related problems are inevitable. While technology holds much promise, the benefits of a specific technology may not be realized due to four common pitfalls: 
       - (1) poor technology design that does not adhere to human factors and ergonomic principles,
          - (2) poor technology interface with the patient or environment,
          - (3) inadequate plan for implementing a new technology into practice,
       - (4) inadequate maintenance plan.

Electrical measurements - Electrical power

Electric power, like mechanical power, is the rate of doing work, measured in watts, and represented by the letter P. The term wattage is used colloquially to mean "electric power in watts." The electric power in watts produced by an electric current I consisting of a charge of Q coulombs every tseconds passing through an electric potential  difference of V is:
