The document discusses several environmental issues including population growth, pollution, habitat loss, and climate change. It explains how burning fossil fuels increases greenhouse gas emissions and warms the planet. It also describes how industrialization and pollution threaten biodiversity by destroying natural habitats and poisoning ecosystems. The text advocates for conservation efforts to protect wildlife, natural resources, and switch to more sustainable practices.

2. • Population growth
• Acid rain
• Acidification of lakes
• Deforestation
• Bioaccumulation
• Ozone depletion
• Carbon-Flouro-Carbons
• Pollution
• Exxon Valdez oil spill
• Global Warming

3. • Industrialization
• Burning fossil fuels
• Non-renewable resources
• Pollution
• Increased CO2 levels

4. • 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

5. • Lakes and
ponds can
become so
acidified that no
life can live in
them!

6. • 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

7. • Water Pollution
• Oil Spills
• Gasoline spills
• Gets into drinking
water

9. • Increase in CO2
• Increase in greenhouse effect
• Increase in global
temperatures

11. • 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.

12. • 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.

13. • The protection,
preservation,
management, or
restoration of wildlife
and of natural
resources such as
forests, soil, and
water.

14. • 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.
