What’s New
We cannot deny that energy is a very precious commodity. It serves many purposes. But the utilization and production of energy have some unwanted effects on the environment. Moreover, the exploitation of these resources has a great impact on our lives. The rapid and increasing consumption of energy creates an energy crisis. As population increases and technological advancement is present, the requirement for these resources becomes vast and complex.
ACTIVITY 1: Fill Me In
Direction: Identify some of the problems arising from the exploitation of natural and energy resources.
####### 1. Results from the utilization of nuclear energy!
- Excavated soil is simply pushed over the side of the exploratory cut, creating ugly scars, landslides, and severe erosion problems!
####### 3. The most dangerous effects are the mutagenic effects (causing abnormal
growths), carcinogenic effects (causing cancer), and teratogenic effects
####### (causing birth defects).

While energy is an indispensable factor in the survival of people and nations and in the progress of a country, we are enjoying the convenience brought about by the utilization of these resources. Major uses of these energy resources are as follows: food production and agriculture; transportation; residential and commercial lighting, cooling, and heating systems; mining, smelting, and industrial processes; and generation of electricity.
Through the years, humans always depend on these different energy resources in their daily activities. However, there are several factors that contribute to the increase in energy consumption like (1) the increase in population, (2) the increase in demand for resources, and (3) the rise in new technology.
The exploitation of energy resources started to emerge in the 19th century as natural resource extraction developed. During the 20th century, energy consumption rapidly increased. Today, about 80% of the world’s energy consumption is sustained by the extraction of fossil fuels, which consists of oil, coal, and gas. Another non- renewable resource that is exploited by man are sub soil minerals such as precious metals that are mainly used in the production of industrial commodities.
Because of these factors, the utilization of the different energy resources led to the following exploitation of man’s activities. Effects of these are as follows:
A. The depletion of fossil fuels- like oil, coal, natural gases, and other nonrenewable energy sources. They, too are, not infinite. The fast-growing population, the increasing demand for resources, and the rise in technology contribute to the consumption of energy sources.
B. The destruction of soil and soil erosion- During the exploration and extraction of fossil fuels, excavated soil is simply pushed over the side of the exploratory cut, creating ugly scars, landslides, and severe erosion problems.
C. Greenhouse gas increased and Thermal pollution- All fuels and power consumed turn up as heat in the environment. They cause an increase in the temperature of the ecosystem which, causes ill effects on the organisms. Examples are combustions of fossil fuels; emissions from automobiles; and when the temperature of a river is increased, the amount of dissolved oxygen is decreased, result of the death of the organism in the river. These are all results of global warming.
D. Water and Material pollution- The energy in any kind of fuel is associated with a material substance, the fuel itself. During the process of consumption, this material substance is transformed into other substances like ashes, smoke, and other gaseous products which, are dumped into the environment as waste products. Examples of these waste products are sulfur dioxide and carbon monoxide. Sulfur dioxide causes throat irritation and respiratory diseases. When sulfur dioxide combines with oxygen it forms into sulfur trioxide. When sulfur trioxide is combined with water, it yields sulfuric acid which, is highly
corrosive and cause rusting of metals, deterioration of fabric, and the corrosion of buildings and sculptures.
E. Radiation pollution- radiation pollution results from the utilization of nuclear energy. You have learned that during fission, the nucleus is split into fragments which, becomes radioactive. Some of these products have short life spans, and their radioactivity dies out quickly, but others have life spans of many years. Therefore, nuclear waste disposal becomes a problem. Unlike sewage, these nuclear wastes cannot be treated in any way to reduce the harmful radioactivity. If improperly disposed of, they cause contamination. Radiation causes cancer and abnormalities.
F. Health hazards- all these types of pollution resulting from the utilization of energy have a common effect 4 health hazards. The most dangerous effects are the mutagenic effects (causing abnormal growths), carcinogenic effects (causing cancer), and teratogenic effects (causing birth defects).
In addition to these environmental effects, there is the problem of clean-up costs and their social consequences. Some pollutants can be reduced to an acceptable level, but such requires expenses.
While energy provides humankind all the conveniences in life, it also has its environmental impact. The increasing population, coupled with the increasing demand for resources, has contributed tremendously to the increasing energy consumption. Likewise, the rise in technology contributed to energy consumption. Increasing energy consumption led to the depletion of energy resources.
