The earth is about 4.5 billion years old, and during its
life, the climate has changed quite often and the planet has experienced an Ice Age, warming, and everything in between. Scientists agree that the Earth's averge termperature has increased by about 1.8° F over the past 200 years. It may not sound like a big change, but it will influence the earth. The earth is covered like a greenhouse, which is used by some farmers, florists, and others to grow plants. A greenhouse is a glass-covered building that absorbs the heat from the sun it is usually very hot. Of course, the earth is not covered with glass, but the greenhouse effect refers to the retention of the sun's warmth in the earth's lower atmosphere by greenhouse gases. The greenhouse glass include mostly carbon dioxide, methane, and nitrous oxide. These gases (instead of glass) act as a blanket for the earth, helping to keep the earth warm enough to support life at an average temperature of about 50° F. An increase in the greenhouse gases the earth to become warmer. Think of it as a heavier blanket. The 'blanket' is created by the gases released into the atmosphere when fossil fuels-such as oil, coal, and natural gas-are burned.
Even a few years ago, very few people had even heard of the
C
word internet. Now it would be difficult to find anyone who has not heard of it. Many of us use it on a regular basis, and most of us have access to it at our homes too. The 'net' in the internet stands for network. A network is two or more computers connected together so that information can be shared or sent from one to the other. The internet is a vast resource for all types of information. You may enjoy using it to do research, download your favourite song or communicate with family and friends. It is like a giant bulletin board for the whole world to see. Since anyone can put anything on the internet, one must be very careful and use both judgement and common sense while accessing and using internet sources.
