The exploration and development of safe alternatives to fossil fuels should be the most important global priority today.
To what extent do you agree or disagree?
Give reasons for your answer and include any relevant example from your own knowledge or experience.
Write at least 250 words.
Fossil fuels like coal, oil and natural gas are the primary source of energy in the world. These fuels have fuelled almost all major industries and economies across the globe. Many experts propose that finding other forms of energy that are safer than these non-renewable ones should be the topmost priority of all the nations. I strongly agree with this view.
To begin with, the world has overused fossil fuels without paying attention to their detrimental effects on our natural environment. Global warming and soaring air pollution levels have become a threat to our planet and our existence. All nations are experiencing a change in their climate. Their citizens are suffering from diseases caused by hazardous air pollutants. Unquestionably, these are international problems and resolving them is beyond the capacity of any one nation.
Furthermore, the reservoirs of coal, crude oil and natural gas are depleting at a rate faster than ever before. The day when these sources will not be able to support us is not very far. Definitely, the way forward is global co-operation which will focus on the research and development of sustainable means of energy. Many wealthy countries like UK, Japan and USA are trying to reduce their dependence on non-renewable fuels. They are developing technology for other eco-friendly forms of energy such as solar, water, wind and geothermal etc. But, developing and poorer nations are not on par with them. I believe that co-ordinated efforts will be fruitful in bridging this gap as well.
Of course, there are several other serious global problems such as illiteracy, poverty, shortage of food and water, unemployment and terrorism etc. They are as important as exploring alternative sources of energy. Nonetheless, the efforts to repair the damaged environment should be prioritized before it is too late.
To conclude, the unquenched thirst for development and the rise in the global population have exacerbated immense pressure on fossil fuels. Personally, I believe that sincere efforts at a global level are required not only to meet the increasing demands of energy but also to mitigate the problems that excessive exploitation of non-renewable fuels has caused.(353 Words)

Alternatives to Fossil Fuels Essay
947 Words4 Pages
Fossil fuels which are hydrocarbons found within the top layer of the crust, are natural resources formed by the decomposition of anaerobic buried dead organisms such as dead plants and animals. They fossilize through the exposure of heat and pressure in the Earth’s crust. Fossil fuels are non-renewable resources because of the millions of years they take to be formed; prime examples are coal, natural gas and oil. When coal, natural gas and oil are burnt they release gases into the atmosphere such as carbon dioxide also known as CO2 which is a greenhouse gas that traps heat from the lowest part of the earth’s atmosphere, which also contributes to global warming. There is also Sulfur dioxide (SO2) which is a key contribution to acid rain,…show more content…
And on top of that during the burning of the fuels there is a release of greenhouse gas, increasing global warming.
Global warming is the warming near the earth's surface that is a result when the earth's atmosphere traps the heat of the sun. The earth’s temperature is increasing but the changes are small, so far, but they are expected to increase and the process to speed up, within the next fifty to one hundred years. The earth may be hotter than it has been in the past million years, as oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Global warming will affect weather everywhere, plants and animals everywhere, people everywhere; humans are warming the earth's atmosphere by burning fuels, cutting down forest, and by taking part in other activities that release certain heat trapping gases into the air. Of course one major cause of global warming is the use of fossil fuels. We have only known for a few thousand years that coal, oil, and natural gas can be burned to provide energy, however that is when began to burn very large quantities of these natural resources and the worldwide consumption of fossil fuel has increased dramatically.
The other option is the energy in water can be
