Humankind has relied heavily on fossil fuels, releasing greenhouse gases that have warmed the planet. Toxins and plastic pollution have accumulated in oceans, land, and air. Technology has become deeply integrated into modern life and is shaping how people interact. While fossil fuels and technology provide benefits, they also pose risks to the environment and human health if not addressed sustainably.

1. THE ANTHROPOCENE
Humankind is responsible for the massive USE of fossil
fuels which has charged the atmosphere and temperature of
the planet. Toxins and plastic are an accumulating problem of
the oceans, land and air, while technology is becoming our
second if not our first nature. Discuss.

3. PROLOGUE
Nowadays, fossil fuels predominate in the production of
energy. According to some researches, they will
continue to be our main energy source until 2030.

5. Generally about fossil fuels
• Fossil fuels are sources of energy which come from
very old life forms, that decomposed within the earth
over millions of years. The three most important fossil
fuels are coal, petroleum and natural gas. They are
considered non-renewable energy forms, because it
took them so long to be created. This means that they
cannot be used again once they have been utilized
(with the exception of natural gas). A fossil fuel can be
in the form of a solid, a liquid or a gas.

6. Generally for fossil fuels
• This type of fuel consists mainly of hydrocarbons,
where energy is stored. For the production of energy all
that is needed is combustion. So essentially, through
electricity we are provided with heating and light for
our house or other appliances and fuel or gas for our
car.
• But by burning fossil fuelswe release various gases
such as carbon dioxide and other gases. Αre these
gases too dangerous when polluting the atmosphere?

7. ADVANTAGES OF FOSSIL
FUELS
https://cdn.instructables.com/FP5/1KYE/I5P7JM6C/FP51KYEI5P7JM6C.MEDIUM.jpg

8. Easily available
• Because of the
increasing demand
of fossil fuels,
science and
technology have
been advanced.
With this fact, the
refineries and the
extraction
procedures have
also improved a lot.

9. Large amount of energy
• Fossil fuels are easily combustible.
• In this way, most engines are powered with little
amounts of fuel.
• They can produce large amounts of energy.

10. High Calorific Value
• Fossil fuels are among
the highest producers of
calorific value in terms of
energy.
• That’s why they are still
preferred over the
renewable sources of
energy or the alternative
sources of energy.

12. Stability
• Fossil fuels are very stable because they are
composed of molecules of carbon and hydrogen.
• Because of their constancy, they are also easy to be
stored as they do not form other compounds after
being stored for a long period of time.

13. Transportation
• The biggest
advantage of using
fossil fuels is that
they can be easily
stored and
transported from
one place to
another.

14. Low Cost
• Fossil fuels are available all over the world and the
methods to extract energy from them are also not that
expensive.
• Unlike other alternative sources like solar power or
wind turbines whose initial investment cost are too
high, fossil fuels have pretty low cost.

15. Easy Set Up
• Construction of
fossil fuel
power plants
can take place
anywhere.

17. Environmental hazards
• When fossil fuels are burnt, they emit carbon dioxide.
• Carbon dioxide is the main cause of global warming and
one of the greenhouse gases.
• High temperatures have devastating effects on our lives
as they lead to many floods because of the melting of
polar ice caps.

19. Acid rain
• When burnt, fossil fuels
also produce sulphur
dioxide, one of the
gases that is
responsible for acid
rain.
• This type of rain
destroys monuments
made of marble or
brickwork and even
crops.

20. Non-renewable
• As we extract fossil fuels
in an increasing rate, one
day we will run out of
sources.
• They are non-renewable
so there is a limited
amount of them and we
are not actually sure
where that limit is.

21. Human health
• Because fossil fuels release greenhouse gases, the
ozone layer has been worn-out and ozone holes
have been created. These holes allow harmful UV
rays to enter the Earth’s atmosphere.
• UV rays affect human life and they cause serious
diseases, particularly skin cancer.

22. Coal-mining dangers
• Extracting coal from
areas with huge
reserves is not only a
difficult and dangerous
task, but it is also a
risk to the health of
the workers.
• Aside from this, coal
mining destroys vast
lands, which can
result in ecological
imbalance. http://www.imsif.com/images/Coal-mining.jpg

23. Affecting marine life
• When fossil fuels are
transported via land, air or
water they pose a threat to
the environment. For
example, leaks in oil
tankers or ships sinking
deep in the sea can cause
huge problems as many
substances of the crude oil
pose serious hazards to
marine life.

25. What is technology?
Definition; The branch of knowledge that deals with
the creation and use of technical means and their
interrelation with life, society and the environment,
drawing upon such subjects as industrial arts,
engineering, applied science and pure science.

26. Technology; our second nature
Technology has become a very important part of our
lives and we consider that we cannot live without it. It is
difficult to find an area which has not been influenced
by technology. From how we cultivate our land to how
we communicate with each other the change is huge.
