Biodiversity
The variety of different
species
of organisms on
earth.
High biodiversity means ecosystems are more
stable
as species depend on each other for
shelter
and food.
Factors that put biodiversity at
risk:
Availability
of water
Temperature
Atmospheric
gases
Waste management
As the human population
increases
, the volume of waste pollution
increases.
Polluting the ecosystem
harms
or
kills
the organisms that live within it.
Water pollution
Open
sewers
can lead into water courses such as streams and rivers which can cause serious illnesses for humans if they drink
contaminated
water.
Air pollution
Combustion of fossil fuels release
carbon dioxide
which contributes to the greenhouse effect and leads to
global warming.
Land use
When land is cleared for humans such as buildings, biodiversity is
reduced.
The
larger
the human population, the more
land
we require.
More
houses
built, more
resources
, more
food
grown and more
waste
produced.
Deforestation
Leads to destroying
habitats
of organisms and
kills
many species.
Up to an estimate of several hundred species lost each day as a result of
deforestation.
Greenhouse effect
The increased release of greenhouse gases creates an
enhanced
greenhouse effect.
Leading to
global warming.
Consequences of global warming
melting of polar ice caps
the rise in
sea levels
weather patterns
changing
species becoming
extinct
animals will
migrate
to find other suitable
habitats.
