A role of the Environmental Ethics in the modern society The inspiration for environmental ethics was the first Earth Day in 1970 when environmentalists started urging philosophers who were involved with environmental groups to do something about environmental ethics. An intellectual climate had developed in the last few years of the 1960s in large part because of the publication of two papers in Science: Lynn White`s “The Historical Roots of our Ecological Crisis” (March 1967) and Garett Hardin`s

The Earth Is Our Only Home! The Importance of Environmental Protection & Practical Steps to Support It By Ven. Jampa Since the second half of the 20thcentury‚ the results of environmental destruction and the exploitationof natural resources have become increasingly obvious. Now‚ 7 billion people are sharing this planet‚ and scientists predict that the population will increase to 10 billion people in this century. However‚ we already face difficulties with dwindling natural resources and environmentalpollution

Gas Chromatography (GC) Definition: Gas chromatography is a physical method of separation in which the components to be separated are distributed between two phases‚ one being a stationary bed of large surface area‚ and the other a gas that percolates through the stationary bed. When the stationary phase is a solid‚ the separation process is more precisely called gas-solid chromatography. Introduction: Gas Chromatography is a technique widely used to separate complex mixtures of substances. Compounds

The key element for fire protection‚ emergency medical and rescue services is people. In order for these complex services to function properly people must be part of the equation. Over the past 25 years the population in the United States‚ let alone the entire world‚ has grown tremendously. As the number of people grow in this country so does the potential of more fires and hazards. During the period of growth the fire service used engineering‚ education and code enforcement to moderate the frequency
