WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become

Evaluating the sustainability of the EU policy: “By 2020‚ 10% of transport fuel in the EU should be supplied from Biofuels” Introduction: The 2009 Renewable Energy Directive (RED) required a 10% share of renewable energy in the transport sector by 2020; biofuels must emit a minimum of 35% less greenhouse gases (GHG) than the fossil fuels they replace‚ increasing to 50% for existing plants in 2017 and 60% for new infrastructure thereafter. The Fuel Quality Directive‚ setting a target of a 6% GHG

CHAPTER ONE 1.1 Introduction Earth is the water planet with more than two-thirds of its surface covered by water. Most of life on Earth is also primarily composed of water; our cells‚ and those of plants and animals are composed of approximately 70 percent water. Vast quantities of water also cycle through the Earth ’s atmosphere‚ oceans‚ land‚ and biosphere over both short and long time scales. This grand cycling of water is called the hydrologic cycle. Precipitation‚ evaporation

The Neolithic and Industrial Revolutions The two changes in the use of the earth’s resources that had the greatest effect on the world population were the Neolithic and the industrial revolutions. The Neolithic revolution (a.k.a. agricultural revolution) was a change in the way of life of our ancestors. It took place about 8000 years ago among various tribes in Asia and the Middle East. It included a transition from foraging and hunting to the domestication of animals (most probably starting
