3 Throughout the world soil is constantly being eroded. There are three major principles that can cause soil to erode‚ leading to soil degradation. Over-cultivation‚ overgrazing‚ and deforestation have huge impacts on the degradation of the soil. There are‚ however‚ actions that can be taken to preserve or correct the conservation of soil. To further understand the prevention of degradation‚ we must fully comprehend the major causes of soil erosion. One major cause of soil erosion is over-cultivation

Conservation and Preservation check pt Conservation is the sustainable use of natural resources including wildlife‚ water‚ air‚ and earth deposits. Some of these natural resources may be renewable or non-renewable. The conservation of renewable resources like trees involves making sure that we are not using more than what we are able to replace. The conservation of non-renewable resources like fossil fuels involves ensuring that we are only using them when we need to. Preservation is maintaining

Evaluation of the soil management strategies in the India The more time goes past‚ the more man starts realising how the management and the way we threat soils is important to insure its preservation and conservation. Nowadays‚ around 9.4 million hectares of soil‚ which represent the 0.5% of the land present on our planet‚ is irreparably damaged and has no longer any biological function. In other words‚ it can no longer be used in any useful way to provide food or other elements to the earth’s

SOURCES OF ENERGY Energy can neither be created nor destroyed. Energy can only be converted from one form to another. E.g. if we drop a plate from a height‚ the potential energy of the plate gets converted mostly to sound energy when it hits the ground‚ chemical energy in the wax is converted to heat energy & light energy on burning. The total energy during a physical or chemical process remains the same. In the above examples‚ energy in the usable form is dissipated to the surroundings in less

The transfer of trace elements between soil and plant is part of chemical element cycling in the nature. The mobility and availability of trace elements are controlled by many factor of Climatic‚ biological and geochemical origins in nature. That means‚ to predict the uptake of trace elements by plants from soil it is important to look at several biotic and abiotic parameters the affect and control the behavior of elements in the soil. The risk to environment and human health of a given trace metals

CHAPTER ONE INTRODUCTION 1.0. Soil – transmitted helminths Soil–transmitted helminths (STHs) are included in the list of the world’s neglected tropical diseases (Molyneux et al.‚ 2005). STHs are major public health problem especially in the developing nations. The species of soil-transmitted helminths that infect humans are concentrated in the developing world‚ and these include the large roundworm Ascaris lumbricoides‚ the whipworm Trichuris trichiura‚ and the hookworm Ancylostoma duodenale

PRESENTATION FOR 8-Cs PROJECT Gas which is used for burning is produced from the fossil fuels‚ which at the moment are decreasing at a much faster rate than they are being produced. Cow Dung is a place below earth surface where all waste of animals and rubbish from city is stored. Together the waste of animals and rubbish produces a gas called bio-gas which can be used for burning. In this way‚ rubbish which is burnt & makes pollution can be made into a useful gas and our fossil fuels can be saved

The Conservation of Races W.E.B. Du Bois The United States of America‚ since its commencement‚ has been a “melting pot” of different nationalities. While the term melting pot sounds forthcoming‚ this is not the case in reality. Many times cultures collide due their differences in ideology‚ culture‚ and geographical proximity. Such culture clashes have marked the history of the United States. Race is usually thought of in the physical sense with difference in skin color‚ hair‚ facial features‚ and
