private lands to which could not be protected under the president’s authority. It wouldn’t be until the 1930’s that we actually see policy emerge with emphasis on the management of forests. In the 1920’s Aldo Leopold began pushing for wilderness conservation. As a member of the U.S. Forest service Leopold successful designated the first wilderness area‚ the Gila National Forest (aldoleopold.org 2000). This would set precedent for future acts involving forest lands through means of passing policy through

FOREST CONSERVATION Forests are one of the most important natural resources that have been gifted to mankind for their sustained existence on earth. Without question‚ they provide us with huge amounts of tangible and intangible benefits‚ without which indeed‚ all life‚ less to say human life‚ would fall under the risk of extinction. Hence‚ it is vital for us to realize this importance of forest cover‚ conserve them‚ and ultimately work towards a sustainable way to maintain our forests and meet

most neglected commodity on the earth. Shifting cultivation on the hill slopes‚ non-adoption of soil conservation techniques‚ and over exploitation of land for crop production due to population stress‚ leads to enormous soil erosion. It will take hundreds of years to form an inch of soil‚ but in no time it gets washed away down the slope due to erosion. SOIL CONSERVATION Soil Conservation is the process by which the loss of soil is checked‚ reducing the velocity of run-off through erosion

Various types of Fuel Cells and their working By : Divykant Vishwakarma 03996404910 EEE 2nd shift S.No. 14 Fuel Cell A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air

Wildlife Conservation Introduction Favoured with a unique geographical location and varied landforms‚ India is home to about one third of known life forms in the world. There are over 500 species of mammals and 2060 species of birds that are truly Indian. Rapid growth of human and livestock population since the turn of the century and the consequent pressure on land due to development have taken an increasingly heavy toll on the country wilderness. One of the major threats facing wildlife is the

THE DEPLETION OF FOSSIL FUELS By Zoe Noonan Introduction As the world is becoming more advanced in technology‚ more energy is being used to keep up with the changing requirements. At the current rate at which energy is being used‚ the world will shortly come to an end of fossil fuels- the world’s primary energy resource. Abstract This research paper outlines the problems being faced by the shortage of fossil fuels‚ the effects they are having on the environment and the possible substitutes

the key sources of energy means; fossil fuels are being depleted in a rapid mode which reflects that we need to concentrate over alternative sources of energy that could also prove to be eco-friendly. But‚ before discussing that it should be better to have an idea about the current scenario and where we are standing today in context of availability of energy resources. At present‚ approximately 80 percent of the energy used by us is supplied via fossil fuels which are called non-renewable energy

GREEN FUEL 1. With the present constraints in the supply line of crude oil through Organization of the Petroleum Exporting Countries (OPEC)‚ ‘Green fuel’ rather well famous as biofuel has already set a new dimension to world’s fuel mythologies of exhausting fossil fuels by next century. It paved the way to the scientists to divert from the traditional chase behind the carbon cycle to discover the ideal fuel for man kind’s usage amidst preserving globe. 2. Biofuel is mainly a type which is distilled

Fossil Fuels which include Petroleum and Natural Gas were formed million years ago from the remains of plants and animals‚ are responsible 40% and 20% respectively for the world ’s energy. They were first discovered about 700-900 years ago‚ however since the first modern petroleum industry began in 1859‚ the demand for fossil fuels has escalated beyond our control. It had taken 50-300 million years to form‚ and yet we have managed to burn roughly half of all global oil reserves in merely 125 years
