Acidification of lakes
•
Deforestation
•
Bioaccumulation
•
Ozone depletion
•
Carbon-Flouro-Carbons
•
Pollution
•
Exxon Valdez oil spill
•
Global Warming
Population Growth Leads To
•
Industrialization
•
Burning fossil fuels
•
Non-renewable resources
•
Pollution
•
Increased CO2 levels
Acid Rain
•
Burning of fossil fuels releases
sulphates and nitrates into air
•
Sulphates and nitrates mix with
water vapor in air and form
sulphuric acid and nitric acid
Acidification of lakes
•
Lakes and
ponds can
become so
acidified that no
life can live in
them!
Deforestation
•
Population growth leads
to the loss of natural
habitats
•
Cut down trees to build
new homes
•
Loss of biodiversity
•
Loss of oxygen
producers and CO2
eliminators
Pollution
•
Water Pollution
•
Oil Spills
•
Gasoline spills
•
Gets into drinking
water
Exxon Valdez oil spill
Global Warming
•
Increase in CO2
•
Increase in greenhouse effect
•
Increase in global
temperatures
What is Biodiversity? Why is it
important?
•
Simply means the diversity, or variety, of
plants and animals and other living things in
a particular area or region.
•
It is important because everything that lives
in an ecosystem is part of the web of life,
including humans. Each species of
vegetation and each creature has a place
on the earth and plays a vital role in the
circle of life. Plant, animal, and insect
species interact and depend upon one
another for what each offers, such as food,
shelter, oxygen, and soil enrichment.
How are humans affecting global
biodiversity?
•
Climate change, brought about by emissions of
greenhouse gases when fossil fuels are burnt, is making
life uncomfortably hot for some species and
uncomfortably cold for others.
•
Pollution is currently poisoning all forms of life, both on
land and in the water, and contributing to climate change.
•
Habitat loss and destruction, usually as a direct
result of human activity and population growth, is a major
force in the loss of species, populations, and
ecosystems.
What is meant by
“CONSERVATION”?
•
The protection,
preservation,
management, or
restoration of wildlife
and of natural
resources such as
forests, soil, and
water.
How we can preserve biodiversity.
•
Do not waste paper, use only as much as you
require. Do not scribble on it or tearing it off
after writing just a line or two.
•
Use recycle paper as far as possible.
•
Try to reuse the envelopes where ever
possible.
•
75% of all fisheries are fully exploited or over-
fished. Species like cod, haddock and halibut
are already threatened. If we do not move
towards sustainable use, there will be no fish
left for our grandchildren.
•
Climate change is considered to be the
greatest challenge for humanity. With
changing conditions, ecosystems and habitats
will change as well. It is an obligation to fight
climate change and make sure that species
can migrate or adapt to new surroundings.
Thank you for watching
