Nutrition Nutrition is a process by which the body takes in breaks down and uses food. Good nutrition is important as it keeps us healthy. It helps us grow‚ develop ‚ prevent diseases and help the body to function properly. Food that gives good nutrition contains substances called nutrients The six basic nutrients are : Carbohydrates Fats and oils Protein Vitamins Minerals Water Carbohydrates : Is an important nutrient as it gives the body heat and energy. It contains starch and sugar

Global Warming Human kind has entered a brand new relationship with the earth. The constant and increasing pressures we are exerting threaten our planets ability to sustain life itself. Change-in the way we think ‚ and in the way we live-is needed now.Global warming is the most urgent environmental problem the world will face in the next decade and the next century. Few‚ if any‚ trends are more important to our future than climate change caused by human activities. Scientist around the world

What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter‚ disasters like hurricanes‚ droughts and floods are getting more frequent The average facade temperature of the globe has augmented more than 1 degree Fahrenheit since 1900 and the speed of warming has been almost three folds the century long average since 1970. This increase in earth’s average temperature is called Global warming. More or less all specialists

Global Warming Glaciers are melting‚ sea levels are rising‚ cloud forests are drying‚ and wildlife is scrambling to keep pace. Its becoming clear that humans have caused most of the pat century’s warming by releasing heat-trapped gases as we power our modern lives‚ called Greenhouse Gases‚ their levels are higher now than in the last 650‚000 years. We call the result global warming and it is causing a set of changes to the earth’s climate. As the earth spins each day‚ the new heat swirls with

Over the past few decades scientist have been observing a warming trend in the over all temperature of the earth. Although the earth has been known to go through warm and cold periods‚ it seems that we humans are causing the earth to heat up this time. The greenhouse effect is causing the earth to go through this warming trend that we call global warming. The greenhouse effect is caused when the infrared radiation from the sun is absorbed in atmospheric gasses such as water vapor‚ carbon dioxide

Global temperatures on the Earth’s surface have increased by 1.1 degrees Fahrenheit during the last century‚ faster than any time in the last 1000 years (Rauber 41). Consequently‚ the 1990s was the warmest decade in the last 1000 years (“Global Warming”). As humans emit fossil fuels‚ greenhouse gasses slowly warm the Earth’s atmosphere (“EPA Global”). This gradual process is known as global warming. As glaciers begin to melt‚ sea levels rise and coastal areas in Florida may suffer immense losses

Global warming is the warming of earth’s land‚ water and atmosphere. Global warming has happened throughout history‚ but has recently become more of an issue. Every year since 2001 has made it on the warmest year record list. There is much debate whether this is a natural phenomenon or if the human population is causing global warming. There is no denying that the earth is getting warmer. As shown in the graph to the right global temperatures have risen from -.4 C to .6 C over a four year period

New items were gradually added to the list‚ ranging from the degradation of ecosystems to threats to human health. Experts in fields from forestry to economics‚ even national security experts‚ pitched in to assess the range of possible consequences. It was impossible to make solid predictions given the complexity of the global system‚ the differences from one region to another‚ and the ways human society itself might try to adapt to the changes. But by the start of the 21st century‚ it was clear

the burning of fossil fuels" - David Bellamy Global warming can be defined as the gradual increase in the temperature of the earth’s atmosphere and the question over what has been causing this increase in temperature has sparked many debates throughout the world. There is certainly evidence to suggest that global warming is a real issue‚ not just an urban myth. Since pre-industrial times (i.e. before the industrial revolution in the late 1700s) global average temperatures have risen by about 0.7°C
