Advantages and Disadvantages of Technology / Преимущества и недостатки технологий
Natural resources are the building blocks on which modern society depends. Knowledge of their physical nature and origins, and the web they weave between all aspects of human society and the physical earth can lay the foundation for a sustainable society.
We agree with the above statement because natural resources are important, as human beings would not exist without them. We use natural resources in everything we do. Therefore we should use our resources with minimal wastage and even ensure we dispose of the waste products in an environment friendly manner and whenever possible, we should recycle.
A natural resource is any form of material organic or inorganic obtainable from the earth’s physical environment to satisfy human needs. Before using any such material however, technology, economic implications, cultural beliefs and possible environmental effects of obtaining and using it have to be considered. Thus, a material thing can be considered as a resource only if the technology for obtaining and utilizing it is both available and acceptable economically and culturally.
If natural resources are not explored wisely, even if they are abundant, they will soon be depleted, leading to serious degradation of the earth’s physical environment, such degradation is already producing; soil erosion, the green house effect and depletion of the ozone layer.
Understanding the environment and its impact on life will help you make positive influences to its conservation and use. If we preserve the environment then future generations may also get to enjoy the flora and fauna that we do today.
Mineral extraction companies and other firms involved with the exploitation of the earths resources should think about the impact their activities and take measures to counter the negative impacts before they have a major effect.
Group work question number five:- «There are spiritual dangers of not owning farm .One is the danger of supposing that breakfast comes from the grocery and the other that heat comes from the fireplace».
A farm is a tract of land set aside for agricultural purposes. These may include keeping and rearing of livestock and the cultivating of the land for crop production. In today’s societies where there is a complex division of labor, very few people depend on working or owning farm or their direct survival. Overall development in the areas of manufacturing, new technologies and techniques of production has enabled the majority of the people in the modern societies to live in cities and concentrate on economic activities other than farming. In other words increase in food production led to an increase in population subsequently encouraged specialization of labor, brought new innovations and so rapid development of societies from a society of farmers to the society in which owning a farm is not vital for one’s immediate survival.
With this in mind owning a farm is still desirable and advantageous in the modern day society. Not only economically, that is to grow food or keeping of livestock for the profit making purposes, but also in the long-term sustainability of environment in which we depend on for our survival. Crop growing serves several economically beneficial services to man and the environment around him. The existence of crop cover prevents soil erosion which is known worldwide as a devastating force.
The consideration that heat comes from the fire place is devasting to Kenya’s already marginal forest cover. This fact is supported by the United Nations assessment that Kenya is below the 10% forest cover required for each nation globally. The effect of this state of Kenya’s forest cover has been felt with the current resurging drought situation and the state of Kenya’s food reserves. Due to these sad facts the government has began programmes and initiatives to assist in the reforestation of Kenya’s forest resource. One of the initiatives includes the reduced use of charcoal as an energy source.
To create public awareness other sources of energy have been put forward as a ?more efficient and effective’ alternatives; Sources such as solar, hydro electric and wind power. Another public awareness campaign includes the informing the public that a reduction of the forest cover will instigate low levels of rain.
