Environmental Awareness, Biodiversity, it's changes, it' threats and consequences.

1. ENVIRONMENTAL
AWARENESS
REPORTERS
ASHLEY JUDE LEGASPI

2. ENVIRONMENTAL AWARENESS
It is the process of being aware
of our natural environment and for an
individual to make choices that can
benefit the environment rather than to
cause harm on it.

3. WHAT IS THE IMPORTANCE OF KNOWING/STUDYING
ENVIRONMENTAL AWARENESS?
The need to know and study environmental
awareness is very important because most of the
environmental issues are the outcomes of an
individuals’ way of living such as improper waste
management that leads to pollution, population
explosion that can lead to industrialization and
urbanization.

4. Our climate, our lives and the future of the
human civilization are all at risk if we do don’t
do something with all these issues. If we make
simple steps and adjustments in our daily routine
we can still restore, help and maintain our
environment. We can still save and prepare the
future of our next generation.

consequences or risks on the environment.

17. Biodiversity

18. Biodiversity
 It is the biological diversity in an environment
as indicated by numbers of different species of
plants and animals.
 It is the variety of life on Earth at all its levels,
from genes to ecosystem
 Bio = Life
 Diversity = Variety
 It is affected by many Earth system processes
and phenomena, including:

19. Climate
Condition
The amount of
sunlight absorbed
at different
latitudes,
temperature.
4
Species
Interaction
Species depend on
other organisms
for food, shelter,
or compete for
food, space, or
nesting sites.
3
Extinction
Decreases
biodiversity.
2
Evolutionary
Process
Generetes new
species traits.

20. Changes in
Biodiversity

21. Changes in Biodiversity
Loss of Species
Human activities have led to a
significant loss of species diversity worldwide,
with many plants, animals, and
microorganisms facing extinction. The loss of
key species can have cascading effects on
ecosystem dynamics and functioning.

22. Changes in Biodiversity
Species Interactions
Changes in biodiversity can alter
species interactions within ecosystems,
affecting processes such as predation,
competition, and mutualism. Disruptions to
these interactions can lead to imbalances and
ecosystem instability.

23. Changes in Biodiversity
Ecosystem Resilience
Reduced biodiversity can decrease the
resilience of ecosystems to environmental
disturbances, making them more vulnerable
to factors such as climate change, disease
outbreaks, and habitat destruction.

24. Threats to
Biodiversity

25. Threats to Biodiversity
Habitat Loss/Destruction
▪ A process by which a natural
habitat becomes incapable of
supporting its native species.
▪ Habitat Loss/Destruction can
be the result of land conversion,
lumber harvesting, material minings,
and agriculture.

26. Threats to Biodiversity
Habitat Fragmentation
▪ A process by which a large
expanse of habitat is transformed into a
number of smaller patches of lesser
total area.
▪ Habitat fragmentation is the
result of the creation of pastures or
crop fields, as well as hydro-electric
reserviors.

27. Threats to Biodiversity
Habitat Degradation
▪ It is when an area can no longer
support native wildlife.
▪ Pollution, invasive species
and disruption of ecosystem
processes such as the changing
intensity of fires are some of the
ways that can cause habitat
degradation.

28. Threats to Biodiversity
Invasive Species
▪ These are organisms that are not
indigenous or native to an area. While not
all non-native species are invasive, the
ones that are classified as such can cause
great economic and environmental harm
to an area.

29. Threats to Biodiversity
Climate Change
▪ Can disrupt the ecological balance
between interdependant and often endangered
plant and animal species.
▪ It is the significant and long lasting
change in the Earth's climate and weather
patterns.

30. Threats to Biodiversity
Pollution
▪It is the action of making an
environment unsuitable or unsafe
for use by introducing man-made
wastes.

31. Threats to Biodiversity
Overexploitation
▪It is when a living resource is removed
from the environment at a rate faster than it
can be replaced.
▪ It can also be known as overfishing or
overharvesting, depending on which species is
being harmed.

32. Threats to Biodiversity
Overpopulation
▪It refers to the condition of
having a population so dense as
to cause environmental
deterioration, an impaired quality
of life, or a population crash.

33. Biodiversity Loss
▪Biodiversity loss refers to the decline or
disappearance of biological diversity.
▪Biodiversity has declined at an alarming
rate in recent years, largely as a result of
human activities.

34. Main Causes of Biodiversity Loss
Climate Change
▪It impacts biodiversity in various levels:
species distribution, population dynamics,
community structures and the functioning of the
ecosystem.

35. Main Causes of Biodiversity Loss
Pollution
▪Pollution causes changes in energy, different
radiation levels, and unwanted biological, physical
and chemical changes in the biosphere, which
includes all other living creatures.

36. Main Causes of Biodiversity Loss
Destruction of Habitat
▪The loss of habitat can fragment ecosystems and can
cause species extinction.
▪It negatively influences biodiversity directly through its
impact on species ubandance, genetic diversity, species richness
and species distribution.

37. Main Causes of Biodiversity Loss
Overexploitation of the Natural Environment
▪The overexploitation of natural resources refers
to their consumption at a speed greater than that of
their natural regeneration, which has an obvious
impact on the planet's flora and fauna.

38. Main Causes of Biodiversity Loss
Invasive Alien Species
▪Invasive species are organisms that entered and established in
the environment from outside of their natural habitat.
▪They act as predetors, competes for food, hybridise with native
species, introduce parasites and diseases, etc.

39. Consequences of Biodiversity Loss

40. Consequences of Biodiversity Loss
Extinction of Species
▪ The alteration and destruction of
habitats puts thousands of species in
danger of extinction.

41. Consequences of Biodiversity Loss
Threats to Human
Beings
▪ Biodiversity loss endangers
human well-being by affecting soil and
water, which are fundamental to food
production.

42. Consequences of Biodiversity Loss
Proliferation of Pests
▪ Imbalance in ecosystems can
lead to the emergence of pests that
damages crops.

43. Consequences of Biodiversity Loss
Increase in CO2 Imission
▪ The capacity of forests and
oceans to absorb CO2 decreases if their
ecosystems are adversely affected.

44. Ways to Prevent Biodiversity
Loss

45. Ways to Prevent Biodiversity Loss
Be Environmentally Aware
▪In order for us to prevent the loss of
biodiversity, we should first be aware of the
problems that surrounds us and the changes
that was made.

46. Ways to Prevent Biodiversity Loss
Conservation
▪ This refers to the protection,
preservation, management, and
restoration of wildlife and natural
resources like forests and bodies of
water.

47. Ways to Prevent Biodiversity Loss
Conservation
In-Situ Conservation Ex-Situ Conservation
▪ Refers to the conservation of
habitats, species and ecosystems
in nature or where they naturally
occur.
▪ Refers to the conservation of
biodiversity outside of natural
habitats.

48. Ways to Prevent Biodiversity Loss
Restoration Ecology
▪ Renewing/ reatoring degraded/
damaged/ destroyed ecosystems and
habitats due to human activities.
