Third are chlorofluorocarbons (CFCs) and similar chemicals‚ which are also implicated in the separate problem of ozone depletion (see #5 below). Nitrous oxide (from fertilizers and other chemicals) is fourth. #2 Earth’s average temperature has risen about 1 degree F in the past 100 years and is projected to rise another 3 to 10 degrees F in the next 100 years.

Chemical Waste Management In the 70’s‚ there was so much neglect to the management of chemical waste. The study of chlorofluorocarbon (CFC) in the 1980’s brought more attention to chemical waste management as it was discovered that CFC depletes the ozone layer [a layer in earth’s atmosphere that protects the earth from the ultraviolet rays from the sun (UV rays)].

America (3). 119 million people are overeating and under-exercising causing Americans to contract this newly classified disease. Damn‚ Americans sure are owning up to our stereotypical laziness.

stream. Ehrlich was pessimist (the prices will increase) in his argument where Simon was optimist (the prices will decrease). Ehrlich pointed out the demographic changes in the world which result in increasing demand‚ emerging the scarcity and depletion of irreversible resources‚ deterioration of environmental resources‚ increasing diseases‚ global warming and so on. On the other side‚ Simon described the hierarchy as; when population increases and over the period of time the income of the people

Unless a person lives in a country where technology is prevalent‚ one’s life is most likely influenced by technology in one way or another. For example if one looks at the devices in a modern day home‚ a refrigerator‚ an electric stove‚ a blender or a toaster oven will be found. In the living room‚ one will most likely have a television and perhaps a computer. A large percentage of people own cell phones to stay connected with friends‚ family‚ colleagues and business associates. The most up to

ESSAY (Question n°4) For decades‚ humans use natural resources for their development. Today‚ we pay for this exploitation. Human lifestyle are responsible of many effects on environment: global warming‚ climate change‚ depletion of Ozone layer‚ deforestation‚ pollution‚ extinction of species… With depleting resources of nature‚ certain ways to save the environment have to be formulated. But who can do something to save the planet: people or governments? This
