While that may be so‚ it is important to understand how the disappearing green cover and the resultant threat to habitats and to human life fits into the bigger picture of life on the planet. The forest is a complex ecosystem - a biological system with distinct‚ myriad interrelationships of the living part of the environment (plants‚ animals and micro-organisms) to each other and to the non-living‚ inorganic

that can be met by conventional energy sources. The solution to long term energy source is the nuclear powered batteries which have a life span of few decades and can pack in energy densities thousands of time greater than conventional battery sources. Hence‚ there is an urgent need to harvest enormous amount of energy released naturally by the tiny bits of radioactive material. Unlike conventional nuclear power generating devices‚ these batteries do not rely on the fission or fusion reactions and

Millions of years before animals lived on land; there were trees on the Earth. But today trees are in serious danger. Everybody knows that trees produce oxygen that we breathe and take carbon dioxide that we exhale that is why trees called the lungs of our world. As man cannot live without lungs‚ so and world cannot exist without trees. Factories‚ power stations and cars emit tons of smoke into the air. This smoke contains sulphur dioxide and nitrogen oxide. These substances mix with water vapor

Nuclear Proliferation INTRODUCTION: In the world today‚ there are many controversies that affect our every day lives‚ and these are important to stay informed about to be informed about. In this paper‚ I will review the history and up rise of nuclear weapons‚ and how nuclear proliferation has become a fear for the world. I will describe in detail what treaties‚ NGO & IGOs are involved with the topic‚ and the nations involved with nuclear proliferation. The more we know about the history and

changes in Earth’s orbit and tilt‚ volcanic activity‚ human activity. 2. How orbital changes may affect climate? Ans. When Earth’s orbit is elliptical‚ Earth encounters more variation in energy from the Sun. The tilt of the Earth’s axis also changes. When the tilt decreases‚ temperature differences between seasons decreases. Wobbling of Earth changes the direction of tilt and can reverse the seasons. 3. How changes in CO₂ concentrations affect global temperatures. Ans. Carbon dioxide is a greenhouse

People are so reliant on the advanced medical technology this world possesses because they believe that it could save their lives‚ make their lives easier‚ and make their appearance change based on the self image they want. Scientific and medical technology will constantly continue to grow because there will always be a medical

Nuclear energy originates from the splitting of uranium atoms in a process called fission. At the power plant‚ the fission process is used to generate heat for producing steam‚ which is used by a turbine to generate electricity. Nuclear energy usually means the part of the energy of an atomic nucleus‚ which can be released by fusion or fission or radioactive decay. What are the Benefits of Nuclear Energy Nuclear energy is the world’s largest source of emission-free energy. Nuclear power plants

Nuclear Weapons Non-Proliferation is a limitation of production such as the Nuclear Non-Proliferation Treaty. The big five: United States‚ Britain‚ France‚ China‚ and former Soviet Union agreed to dismantle arsenals and signatory nations would not possess nuclear weapons (Conn). Although North Korea has become the world’s ninth nuclear power‚ they withdrew from the treaty in January 2003. Since then‚ North Korea processed enough plutonium for five nuclear bombs (Norris). America should and does
