Environmental Engineering

1. Science and Its
Impact on Society

2. Science and its impact on Society
•Science helps solve the world’s
major problems such as poverty,
famine and pestilence

3. Science and its impact on Society
•Science has helped mankind
advance in the fields of technology,
agriculture, medicine, etc.

4. Science and its impact on Society
•Engineering is one of the
applications of science that helps
address these issues

5. Science and its impact on Society
Question: Therefore, masasabi ba
natin na ang science and its
applications gaya ng engineering
ay kakampi natin sa paglutas ng
mga problema ng mundo?

6. Science and its impact on Society
•However, the rapid development
in science comes with a price: the
degradation of the environment,
depletion of natural resources,
pollution, energy crisis, to name a
few

7. Science and its impact on Society
•So, in summary, science which
used to be viewed as an ally and
solution, turns out to be the
enemy and the problem itself

8. Science and its impact on Society
•Hence, we realize that in applying
science, considerations about the
welfare of the environment cannot
be ignored and in fact must be our
primary concern

9. Scope and
Meaning of Ecology

10. What is Ecology?
Ecology is a scientific discipline
interrelated with a wide variety of
fields of study. Its primary focus is
on the individual’s relationship
with the environment.

11. What is Ecology?
Therefore, ecology deals not
with what is within the
organism but with what is
outside the organism.

12. The levels of organization that make
up the outside of the organism are:
1. Population – a group of
organisms of the same kind

13. The levels of organization that make
up the outside of the organism are:
2. Community – a group of
populations living together in
a given place

14. The levels of organization that make
up the outside of the organism are:
3. Ecosystem – the basic unit of
ecology, refers to the interaction
between the organisms and its
environment; it includes
population, community, habitat
and the environment

15. The levels of organization that make
up the outside of the organism are:
4. Biosphere – the world of life; it is
the part of the earth where life
operates; it is a system capable of
capturing, converting, storing and
utilizing the energy of the sun to
support life

16. Therefore, in summary…
Ecology is the harmonious
partnership of an organism
with nature.

17. So…

18. If the organism is a tree…
What will its nature consist of?

19. A tree’s nature will consist of soil, insects, rainfall, fungi,
bacteria, light and other organisms including man.

20. If the organism is man…
What will its nature consist of?

21. Man’s nature will consist of the hills and valleys, the tress, the rivers,
and the other organisms that surround him, including man.
