1. FUNDAMENTALS OF
BIOETHICS AND
BIOSAFETY
(The Environment)
Presented by: Mahmoud Bahnasi
Group No: 72

2. Topics to be discussed
 What is the Environment ?
 Why is the Environment is important ?
 How do we affect the Environment ?
 Pollution of the Environment.
 How to save the Environment.

3. WHAT IS THE
ENVIRONMENT?

4. o The environment is something you are very familiar with.
It's everything that makes up our surroundings and affects
our ability to live on the earth—the air we breathe, the water
that covers most of the earth's surface, the plants and
animals around us, and much more.
o In recent years, scientists have been carefully examining the
ways that people affect the environment. They have found
that we are causing air pollution, deforestation, acid rain,
and other problems that are dangerous both to the earth and
to ourselves.

5. WHY IS THE ENVIRONMENT IS
IMPORTANT?

6.  The environment is important because
everything that supports the survival of
human beings is dependent on it. It is simply
the only home of mankind, making it the
most important aspect in life. Wellness of the
environment directly relates to the wellness
and health in human beings and every other
species. In addition, the environment
provides remarkable beauty.

7. HOW DO WE AFFECT THE
ENVIRONMENT?

8. o Human activities produce a lot of waste
materials which are thrown away into the
environment. These wastes cause
pollution of air, water and soil.
o The waste materials produced are of two
main types. They are biodegradable
wastes and non biodegradable wastes.

9. 1) Biodegradable wastes :- are wastes which
are decomposed into harmless substances by
microorganisms.
Ex :- vegetables, fruits, cereals, cotton, wool,
wood, leather, paper, animal dung, animal
bones etc.

10. 2) Non biodegradable wastes :- are wastes
which are not decomposed by microorganisms.
Ex :- polythene bags, plastics, synthetic fibers, glass,
metals, synthetic rubber, insecticides, pesticides etc.

12. POLLUTION OF THE
ENVIRONMENT

13. Environmental pollution is the contamination of the
physical and biological components of the earth/atmosphere
system to such an extent that normal environmental
processes are adversely affected.

14. Types Of Environmental Pollution
There are three major types of environmental pollution:-
 Air pollution
 Water pollution
 Soil pollution

15. AIR
POLLUTION
o Air pollution is the introduction into the atmosphere of
chemicals, particulate matter, or biological materials that
cause discomfort, disease, or death to humans, damage
other living organisms such as food crops, or damage the
natural environment or built environment. Smoke from
chimneys, automobile exhaust, burning of fossil fuels and
forest fires result in air pollution.

16. WATER POLLUTION
o Water pollution is the contamination of water bodies(e.g.
lakes, rivers, oceans, aquifers and groundwater). Water
pollution occurs when pollutants are discharged directly or
indirectly into water bodies without adequate treatment to
remove harmful compounds.

17. SOIL POLLUTION
o Soil contamination or soil pollution is caused by the presence of
xenobiotic (human-made) chemicals or other alteration in the
natural soil environment. It is typically caused by industrial
activity, agricultural chemicals, or improper disposal of waste. The
most common chemicals involved are petroleum hydrocarbons, poly
nuclear aromatic hydrocarbons(such as naphthalene and
benzo(a)pyrene),solvents, pesticides, lead, and other heavy metals.
Contamination is correlated with the degree of industrialization and
intensity of chemical usage.

18. HOW TO SAVE THE
ENVIRONMENT

19. • Run your air conditioner sparingly or not at all. Air conditioners use a
great deal of electricity.
• Don't use electronic exercise
machines

20. • Bring your own paper or cloth bags
to the supermarket.
• Recycle all you can.

21. • Avoid using disposable items.
• Plant a tree
• Reduce garbage

22. Suggestions to save our Planet-
Earth :-
 Conserve water .
Conserve energy.
Grow more trees.
Recycle the wastage.
Ban the polythene.
Use renewable resources.

23. “We were born to help the
world, not to destroy it,
Then why we are
destroying the
environment?”
