Global warming Essay is one of the most frequently asked topic especially from environmental perspective. Global warming is the current increase in temperature of the Earth’s surface- both land and water as well as its atmosphere. Average temperatures around the world have risen by 0.75°C over the last 100 years about two thirds of this increase has occurred since 1975.
When the level of gasses caused by cars and factories increase in the atmosphere, the layer of greenhouse gasses surrounding the earth increases in thickness. This means that when the sun rays are reflected by the earth, they come into contact with the thick layer of greenhouse gasses surrounding the earth and all of the heat is trapped. No amount of heat goes out to the outer space. This leads to increase in temperatures, and the earth gradually starts to become warmer.
More than 80% of the world-wide energy demand is currently supplied by the fossil fuels coal, oil or gas. It will be impossible to find alternative sources, which could replace fossil fuels in the short or medium term. The energy demand is simply too high.
Deforestation has become a massive responsibility of humans and transforming forests into farms has a significant number of impacts as far as greenhouse gas emissions are concerned. For centuries, people have burned and cut down forests to clear land for agriculture. This has a double effect on the atmosphere both emitting carbon dioxide into the atmosphere and simultaneously reducing the number of trees that can remove carbon dioxide from the air.
In our technology and scientific minded world, we seem to have forgotten that mankind is only a comparativelynegligible part of Nature.
We believe to be able to control Nature instead of trying to arrange ourselves with Nature. This arrogance is the true main cause of global warming. As a matter of fact, some people still believe that technical solutions alone would be sufficient to fight global warming.
A successful approach to fighting global warming and other consequences of climate change will require vision and expertise across corrections.
The transportation sector’s emissions have increased at a faster rate than any other energy-using sector over the past decade. A variety of solutions are at hand like switching to low-carbon fuels, and reducing vehicle miles traveled through smart growth and more efficient mass transportation systems.
A shift to renewable sources of energy such as wind, solar and hydropower will help bring down demand for fossils fuels and eventually lower the level of greenhouse gasses emitted into the atmosphere.
Taken together, tropical deforestation and emissions from agriculture represent nearly 30 percent of the world’s heat-trapping emissions. We can fight global warming by reducing emissions from deforestation and forest degradation and by making our food production practices more sustainable.
Trees play a critical role in maintaining greenhouse gas balance. If you have the resources to plant a tree, you better start digging to save the planet. Abundance of trees would effectively stabilize the emissions caused by factories, cars, and other human activities.
Pollution from vehicles account for major portion of carbon emissions. Usage of public transportation, carpooling and low carbon fuels not only reduce pollution but also reduce vehicular traffic on the road. In the long run, public transportation appear more cost friendly and doesn’t pinch the pocket.
Lastly, not the others need to change, we must change ourselves. There are no international treaties or additional national laws required to start changing. We can start to change our consciousness immediately. It is really only about our personal behavior- independent of what others do or don’t do.
