Hello friends, I wish to express my views on one of the important topics of the twenty first century. It is the Global Warming Issue.
Let us first understand what it is :
Global warming is the steady increase in the
average temperatures of Earth's atmosphere (and Earth's surface). The
measurements are taken over long duration of time. Our atmosphere has
been getting warmer much faster in the last two decades as compared to the
temperature rises in the previous century. Obviously, it concerns the whole of the world.
What are the reasons really ?
One of the main reasons for the warming is the increased
emissions of greenhouse gases, by people and their activities. These
gases are water vapor, carbon dioxide, methane, chloroflurocarbon (CFC) and
Ozone. It seems even the clouds could contribute to the radiation
levels. The ozone layer depletion is one result of the green house gases,
by free radical Chlorine ions produced by UV radiation from the Sun. If
ozone layer becomes ineffective, then we all will suffer.
Deforestation and fossil fuel burning are some causes
that increased the amounts of these gases in the atmosphere. Burning of gas,
coal, oil, flares, cement production etc are reasons too. Global
warming has an effect on the climate at many locations, affecting crops and
human system. There have been many economic loses.
What can we do about it ?
There are some efforts by various governments for
reducing vehicular pollutions. There must be more mitigation activities like
enhancing the carbon sink, natural sink (reforestation), increasing
energy efficiency. Utilizing more of nuclear energy and renewable energy
sources can also mitigate greenhouse gas amounts. Awareness is required. Too much of selfishness must be avoided and common welfare must be respected more.
Finally, now we all understand the harms of global warming. So we all
must agree together to minimize the global warming effects and stop
exploitation of the environment and ecosystem for short spanned
selfishness. Save Earth and Save atmosphere.
