Environmental issues are harmful effects of human activitity on the biophysical environment. Environmentalism‚ a socialand environmental movement that started in the 1960s‚ addresses environmental issues through advocacy‚ education and activism. The carbon dioxide equivalent of greenhouse gases (GHG) in the atmosphere has already exceeded 400 parts per million (NOAA) (with total "long-term" GHG exceeding 455 parts per million). (Intergovernmental Panel on Climate Change Report) This level is considered

Classification and Marine Biodiversity Important Background Information that you need to know and understand: (Understand the Key Concepts) Key words: binominal system of naming; science of classification is taxonomy; species; levels of classification (know them); dichotomous identification key; 5 kingdoms; etc… CLASSIFICATION Our oceans have a great variety of life forms. Thousands of new species are discovered each year. We need to identify‚ name‚ and know the biology of all the marine species.

But there is a significant pending problem in the ozone layer. Each year‚ a large hole appears in it. It is not an actual hole‚ like a hole in a pocket‚ but a thinning in the layer that shows up on satellite pictures. The "hole" is located over Antarctica. It covers an area about the size of the United States. Experiments done in Antarctica show that the hole in the ozone layer appears to let in twice as much ultraviolet radiation as normal‚ according to measurements researchers made there only

THE EFFECT OF GLOBAL WARMING Introduction One of the most agent controversial topics that are discussed in the world is global warming. Global warming and its effects are real and various scientists unlock the past mysteries and analyze today’s activities‚ they issue warnings that the future generations will be in jeopardy. Overwhelming evidence that the world’s climate is changing due to various human activities exists. Since the industrial revolution‚ various human activities such as agriculture

climate of the earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate‚ a problem that is referred to as "global warming." This paper will attempt to explore this very issue‚ its causes‚ dangerous and somehow deadly effects and how we could deal with this global crisis. Global warming has become perhaps the most complicated issue facing world leaders. Warnings from the scientific community are becoming louder‚ as an increasing body of science points

Global Warming is an Ethical Issue By Alan AtKisson "Ethics" is a word that does not usually get the blood flowing. It calls up images of Aristotle‚ schoolteachers‚ hearings where political leaders weakly defend their honor after having done something foolish that everyone else understands to be wrong. "Ethical issues‚" as a phrase‚ is even worse. Ethical issues are often precisely the ones we prefer to avoid‚ because they force us to confront the sometimes muddy difference between doing right

I. WHAT IS GLOBAL WARMING? Global warming is the gradual increase of the Earth’s average measured temperature overtime. This measured average temperature is derived from both the near-surface air as well as ocean waters. Scientists began measuring this temperature beginning in the mid-20th century and have continued to monitor fluctuations and deviations in measurements ever since. The average global temperature increased approximately 1.33°F over the past 100 years ending in 2005. This led the

lately we understand how destructive it would be if this process to be continued. Although there are many organizations established for the management and protection of forests‚ they have not always been active for the purpose they were meant to be. While carrying out this study‚ I collected data on the statistics of deforestation‚ the main reasons for it‚ countries and regions that mostly produce or consume lumber‚ the projects which helped to lower the rates of deforestation and how they worked out

Introduction Nowadays‚ Global warming is an incontrovertible fact‚ which proves that our planet and its climate are in trouble. Well global warming is a term that denotes a slow warming of the earth’s regular temperature. It was also named exclusively man-made effects‚ in particular carbon dioxide. Carbon dioxide has largely increased during the past forty years‚ and scientists concluded that the average earth temperature has increased solely based on man-made activities such
