  • Essay / Human Activity and Energy Sources - 976

    Earth's resources, such as water, productive agricultural land and energy, provide the basic foundations of our continued existence on earth. However, with continued human activities, for example logging and charcoal burning, these resources are rapidly depleting. Human habitation and increased consumption of natural resources cause untold destruction. Global climate change, the rapid depletion of freshwater catchments, the decline in forest cover, the ever-decreasing fish stocks in our seas and oceans, and the abandonment of agricultural land are some of the effects resulting from human occupation and activities. Poaching, another human activity, leads to the extinction of some animal species, thus labeling them as endangered. For life to continue on earth, man will have to learn to make his way of life sustainable. Such a measure will greatly contribute to guaranteeing the protection of natural resources and thus the balance of the delicate ecosystem. It is essential that world governments begin to educate their citizens on the importance of conserving the ecosystem (Austria 3). This article, from local to global level, aims to analyze the relationship between human activities, Earth resources and the use of energy resources. The article will also evaluate the relationships between humans and energy resources, for example the sun. The Earth is endowed with natural resources essential to human existence. These resources are generally geological in nature and can therefore be extracted. Some of the earth's resources that man extracts and uses include: energy sources, for example oil, natural gas, uranium and coal; non-metallic sources for example r...... middle of paper ......ring that every home be provided with a solar lamp because unlike kerosene, solar energy is renewable. Solar energy is essential because it can be harnessed from the sun and therefore reused again and again. Renewable and non-renewable energy sources generally have advantages and disadvantages. Those who prefer natural gas say it is less polluting than coal and other fuels because it leaves no residue. In addition, its price is reasonable compared to coal. Natural gas is not renewable and can therefore be depleted. Hydropower is less expensive to operate, although it threatens marine life. It also requires building a dam, which can be costly. On the other hand, crude oil is easily available and relatively affordable, but its spills usually pose a danger to the ecosystem. Its extraction degrades the environment and therefore constitutes a danger for marine life (Sandra 2).
