Then‚ the equations developed at microscopic level are needed in order to provide some input into problem solving at macroscopic level. At all three levels of description (molecular‚ microscopic & macroscopic)‚ the conservation law play a key

Myra Willard’s 1920’s context influences her view that the ‘White Australia Policy’ was valid to ensure that the Australian population formed a stable society and a strong sense of nationalism. Willard states that the reasoning for the ‘White Australia Policy’ originated from the 1850’s gold rush era. It was believed the policy needed to be established as countries‚ including America‚ struggled with the influence of non-white races. The 19th Century thought that continued into Willard’s context was

Conservation of Biodiversity One of the most pressing environmental issues today is the conservation of biodiversity. Many factors threaten the world’s biological heritage. The challenge is for nations‚ government agencies‚ organisations and individuals to protect and enhance biological diversity‚ while continuing to meet people’s needs for natural resources. Biodiversity is the existence of a large number of different kinds of animals and plants which make a balanced environment. Biodiversity

HomeExamples and SamplesIs Oil and Gas Conservation Relevant? Is Oil and Gas Conservation Relevant? Oil and natural gas are non-renewable sources of energy. There have been numerous attempts to minimize the depletion of these two resources. Scientists have proposed many reasons for the high importance of their conservation. Oil and natural gas conservation involves the use of these resources in a better and a more well-organized manner with respect to economic‚ social and ambient expenses

to instigate wildlife conservation efforts in India‚ World Wildlife Fund has set up various groups. India hosts diverse kinds of wildlife species possibly due to the broad range of weather‚ soil‚ climate‚ and other similar factors. On the negative side‚ however‚ there are certain species that are threatened or vulnerable and are required pro¬¬tection. Perhaps the need of the time is to put more and more conservation efforts to protect wildlife in India. Wildlife Conservation Efforts in India In

Water conservation From Wikipedia‚ the free encyclopedia United States postal stamp advocating water conservation. Water conservation encompasses the policies‚ strategies and activities to manage fresh water as a sustainable resource‚ to protect the water environment‚ and to meet current and future human demand. Population‚ household size and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources especially in manufacturing and

Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use‚ which refers to using less energy for a constant service. For example‚ driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services‚ it can result in

Intro Forest Conservation is the practice of planting and maintaining forested areas for the benefit and sustainability of future generations. Around the year 1900 in the United States‚ forest conservation became popular with the uses of natural resources. It is the upkeep of the natural resources within a forest that are beneficial to both humans and the ecosystem. Forest conservation acts to maintain‚ plan‚ and improve forested areas. Forests provide wildlife with a suitable habitat for living

WATER Conservation INTRODUCTION: Water is essential for life on earth. Water is needed for growing food‚ keeping ourselves clean‚ generating power‚ controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation: Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning‚ manufacturing‚ and agricultural irrigation
