2. Fossil Fuels
Fossil fuels are fuels created by natural proceedings such as anaerobic
decomposition of buried dead organisms
There are several different types of fossil fuels that exist depending on
temperature and pressure conditions that were created throughout the
years.
There are three primary varieties of fossil fuels. These are coal, oil, and
natural gas.
3. Coal
Coal is a carbon-rich material that most often occurs in stratified
sedimentary deposits
It is one of the most important primary fossil fuels
Coal is abundant, affordable, easy to transport, store and use, and
furthermore free of geopolitical tensions. As a result of its capacities
nowadays it is very popular
4. oil
Fuel oil is a fraction obtained from petroleum distillation
Oil is made of long hydrocarbon chains
It is one of the most popular and commercial fuels
It has extremely many uses: usually used for heating and transportation
Types of oil: Diesel, Gasoline, Kerosene, Naphtha
5. Natural Gas
Natural gas is a naturally produced hydrocarbon gas
Natural gas is found deep under the ground on rock formations and it is
associated with other hydrocarbon reservoirs
Natural gas is used as a source of energy for heating, cooking, and
electricity generation
It is also used as fuel for vehicles and as a chemical for plastics and other
commercially important organic materials.
It is a non-renewable resource
7. The use of fossil fuels today
Indeed, we can not imagine our life without using fossil fuels. They have a
vital role and are necessary in our daily life because they offer multiple
uses.
Some uses of fossil fuels nowadays are: heating, combustible liquids for
means of transport such as cars, buses, trains, airplanes etc., power
electricity plants, medicines, cosmetics, plastics, synthetic fabrics, and
lubricants, the production of electricity that is necessary for successful
daily activities.
8. Advantages of fossil fuels
Fossil fuels are able to generate huge amounts of electricity in a short
time
Fossil fuels are accessible and very easy to find
Most of them are abundant
Fossil fuels are very efficient and useful in daily life
Power stations that make use of fossil fuels can be constructed in almost
any location.
9. Disadvantages of fossil fuels
Pollution is a major disadvantage of fossil fuels
Because of their burning they give off carbon dioxide thereby causing a
greenhouse effect
It has induced climate changes
Destruction of wide areas of land
fossil fuels also endanger not only the lives of the people but also the lives
of the animals
10. The impact of fossil fuels on human
health
Fossil-fuel burning contributes to the build-up of carbon dioxide. In the
atmosphere, this CO2 can trap the sun’s heat, leading to global warming. A
number of recent studies have linked hotter air temperature increase with
diseases of the lungs and heart
Exposure to air pollution can induce behavior problems and learning
difficulties.
Fossil-fuel pollution can cause breathing diseases. These include asthma
and bronchitis
For young people: Pollution exposures may even lower a child’s IQ or lead
to attention deficit hyperactivity disorder
Pollution can cause premature death
11. TO SUM UP:
FOSSIL FUELS CREATE: Acid Rain
Climate Change
Global warming
Land and Water Pollution
Air pollution
The green house effect
12. The Industrial revolution
The Industrial Revolution was the converting to new manufacturing
procedures in the period from about 1760 to between 1820 and 1840
This transition included: from hand production methods to machines,
new chemical manufacturing processes, improved efficiency of water
power, the development of machine tools and the rise of the factory
system.
The Industrial revolution had radically changed the daily life of people and
that is the reason why it constitutes a major turning point in history
13.
14. Positive impact of the industrial
revolution
Products were produced a lot easier and faster
With machines the production was rapidly increased and as a result a lot
of products were produced in a short amount of time
Prices of products went down because by then the construction process
was very simple
Mass production also lead to an increased supply of goods
More accessibility to a product
The labor needs gave the opportunity to many people to have an income.
So, this improved the standards of living
15. Negative impact of the industrial
revolution
Working in a factory is something unpleasant for the people
Long working hours without breaks. It was very exhausting
Working under pressure and difficult conditions without the necessary
hygiene
Machinery was unsafe. People were prone to injuries unless they were
very careful
Factories were unhealthy places and that is the reason why many people
were infected
There wss little compensation for health injuries and illnesses
Smoke was produced by the factory and the ultimate result was air
pollution and the existence of many illnesses
16. toxics
Toxics are poisonous materials which are capable of causing death or
serious debilitation
Toxics have extremely harmful effects. Some of these effects are:
Coronary heart disease is now the leading cause of death
Asthma and upper respiratory illnesses
Particulate matter in air pollution
Brain injury
Serious eye and skin irritation
Cancer
17. TECHNOLOGY
By definition Technology is the collection
of techniques, skills, methods and processes used in the production
of goods or services or in the accomplishment of objectives, such
as scientific investigation
18. How technology affects our lives
Technology, indeed, affects our lives immensely. Without technology, many
things would not be able to materialize. Technology has made our lives
more enjoyable and easy
In the twenty-first century, one of the most important innovations would be
the Internet. The Internet is a system, which allows people to communicate
globally. This means that we have the opportunity to communicate with
people not only in the same country but also with people who live abroad
Another part of technology in our life would be mobile technology. With
mobile technology, people's lives are made easier as they can contact
each other anywhere and anytime they want to. As far as I am concerned,
mobile phones constitute more than a necessity in our life
20. In the 1990s, the dominant means of communication shifted from the
telephone to email as the Internet became commonplace.
During the first decade of this century, the form of communication
developed into communication available at anytime and anywhere
In the 2010s, it was assumed that optimum communication, in which the
means of communication is optimized according to the users' situations,
would become the norm.
21. Fields influenced by technology
Technology has contributed to the development of many areas
As we point out above a lot of achievements have been attained with the
aid of technology in the field of communication. But there have also been
medical achievements, business and many transportation developments
that play a major role in the daily life of people because firstly medical
achievements have led to the treatment of many diseases and thus many
human lives have been saved. Secondly, concerning transportation the
movement of people from one place to another without being too costly
and exhausting has been facilitated.
22. Advantages of technology
Easy Access to information
Encourages innovation and creativity
Improved communication
The convenience of Traveling
Improved housing and lifestyle
Improved Entertainment
Convenience in Education
23. Disadvantages of technology
Increased loneliness (isolated from the outside world)
Virtual reality
Competency (increased dependency on modern tools)
Job loss (Modern technology has replaced many humans with robots that
are more efficient and cost less)
24. Negative impact of technology on
human health
Technology can have a large impact on users' mental and physical health.
Beside affecting users' mental health, use of technology can also have
negative repercussions on physical health.
Mental and physical problems:
psychological issues such as distraction, narcissism, expectation of instant
gratification, and even depression
Physical health problems:
Exaggerated mobile use something that can cause cancer
Poor sleeping habits (using a laptop or a cell phone late at night is
something very usual and simultaneously very destructive for the brain)
Vision problems
25. Negative impact of technology on
human health
Back and neck pain
Obesity risk, most of us are content in front of a screen without having the
need to take some exercise in order to be fit. As a result we don’t move a
lot and unwillingly we become fat)
Stress
To conclude, nowadays technology dominates our life. We can’t imagine our
life without technology because it offers a lot of facilities and constitutes a
necessary mean that makes our life comfortable. But, aside from the
numerous advantages, technology also has a lot of negative consequences
regarding our health and that’s the reason why we should limit our use of
technology especially concerning communication and gadgets.
