Essay Amanda Liao 09/05/13 Clean Water In today’s world‚ one of the most basic problems facing our society is the absence of clean water that we use and drink in daily life. The importance of clean water is self-explanatory. In spite of the fact that 70% of the earth’s surface is covered by water‚ there is only 2.53%of fresh water that we can actually use. For the only 2.53% of fresh water‚ some is not safe and clean to use and it is harmful to human body. Polluted water is a big risk to our health‚

Forms of Energy Energy exists in many forms‚ and when these change‚ energy is conserved. Different forms of energy include the following: Mechanical Thermal Chemical Electrical Electromagnetic Nuclear energy All of these types of energy have the ability to do work‚ which is also the definition of energy. Additionally‚ they have other properties‚ which are specific to their own specific form. Nuclear Energy Nuclear energy is energy in the

Till Now we have studied that energy is the ability of a body to do work .it can also be defined as the ability of a body to bring some change is the energy of that body. Energy is very necessary for human beings; every thing in the universe possessed some energy. There are two main kinds of Energy 1. Kinetic Energy 2. potential Energy Kinetic energy is produced by the motion

issues in today’s world is that of energy sources to power an increasing global demand. Traditionally‚ humans have converted energy from natural resources like coal and natural gas for use. However‚ these sources of energy are both nonrenewable and cause large amounts of pollution. As we progress through the 21st century‚ renewable energy sources like solar and wind energy will see increased use to replace traditional sources. One of these sources‚ wind energy‚ is seeing a rise in development because

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction

Writing Practice Renewable energy has a positive effect on economy. Do you agree? As the fossil fuels resources have been continually mind in recent years. The lack of energy resources is one of the greatest challenges faced by government in Australia. Therefore‚ the new energy resources are promoted and developed such as nuclear power and renewable energy. Some in Australia argued that development of new energy resources not only alleviates the shortage of fossil fuels resources and protects
