A Disappearing World


I need you all to close your eyes. Take a deep breathe in and slowly breathe out. Now picture this. A calm, serene and tranquil environment. Enrobed in a thick luxurious blanket- it helps to keep the place balanced. The warm sun silently filters through, gently warming your skin, greenery all around you, birds chirping and a light breeze makes the leaves whistle. Oh! How peaceful.
Suddenly with a bang, a huge hole occurs in the thick blanket.Whats happening, everything is upset. Now there is too much sunlight, there are no more birds singing and the greenery has silently vanished. A gentle breeze now turns into a violent storm.
Our heaven on earth has turned into a disaster zone. You probably thinking, ‘’Man, this girl watches too many movies.’’ But unfortunately this is the truth my dear friends. Our planet is heading for a disaster and is crying for help. All we do is stand back and relax. Now I welcome you to our terse reality, our disappearing world and to global warming.

‘’Global warming’’- words often spoken about but never taken into consideration.
Global warming is the increase in the average temperature of the Earth, near its surface and its oceans, and is mainly influenced by human activities. Now what on Earth does an increase in temperature have to do with us, right? WRONG! An increase in global temperature in turn causes other changes, including sea level rising and changes in the amount and patterns of rainfall. There may also be an increase in the frequency and intensity of extreme whether events such as tsunamis, hurricanes, earthquakes, floods, volcanic eruptions and more. Other effects may include changes in agricultural yields, glacier retreat, a difference in season change, species extinctions and an increase in the range of disease vectors. You tell me how that doesn’t affect our lives!
Now that we know what it’s doing we now have to stop it, but before that we need to know how it is caused. Ever heard about the green-house effect? The green house effect is unquestionably real and helps to regulate the temperature of our planet. It is essential for life on Earth and is one of Earth’s natural processors. It is the result in heat absorption by certain gases in the atmosphere and re-radiation downward of some of that same heat back onto Earth. The concern is not that we have a green-house effect rather it is weather human activities are leading to the enhancement of it. Human activity had been increasing the concentration of green-house gases in the atmosphere. Mostly carbon dioxide, from combustion of fossil fuels such as coal, oil and gas.

Scientist have predicted that global temperature will increase anywhere from 1.4 degrees Celsius to 1.5 degrees Celsius from 1990 to the year 2100. Also that snow-extent and sea-ice will decrease further in the northern hemisphere, and that glaciers and ice-caps are expected to continue to retreat.

Before we are taken from this world, lets leave it a place to be seen for the future generations. A place with no health hazards, one of peace and tranquility,
joy and happiness. Lets not leave behind a devastating past. Lets not be selfish, it is not always about what we can take but rather what we can give. So lets leave behind a beautiful world.
