OBJECTIVES
 To determine what is environmental overconsumption.
 To list and define factors causing overconsumption of
resources- Overpopulation and Overexploitation.
 To identify and explain ways environmental resources
are overexploited.
 To establish the effect of over consumption on the
Earth including Habitat Loss.
OVER CONSUMPTION
Overconsumption exists when resources
are consumed at an unsustainable level as
measured by the ecosystem’s capacity.
OVER POPULATION
Increase in people means increase in
consumption, resulting in depletion of
resources and/or pollution. This threatens the
carrying capacity of a naturally resourcelimited collection of global ecologies.

World Population
18001 Billion
19302 Billion
19603 Billion
19754 Billion
19875 Billion
19996 Billion
20157.5 Billion
OVER EXPLOITATION
The unsustainable use of natural
resources and overexploitation, which
occurs when harvesting exceeds
reproduction of wild plant and animal
species.
OVER FISHING
 is still widespread across the developing Caribbean
region with fish stocks fished down beyond maximum
sustainable yields (meaning that less fishing pressure now
would allow stocks to recover); thirty per cent of
Community fish stocks are overfished outside safe
biological limits that may not allow their recovery.
NON SUSTAINABLE
FOREST MANAGEMENT
Deforestation , the drainage of peat lands and
wet forest, fertilization and forest-tree genetic
‘improvement’ have had a particularly negative
effect on the biodiversity values of forests.
PRESSURES ON WATER
RESOURCES
This has increased in recent decades and in
many locations agriculture, energy supply,
industry, public water supply and tourism pose
a threat to water resources, with demand often
exceeding availability.
INTRODUCTION OF
EXOTIC SPECIES
An introduced species (also known as an exotic
species) is an organism that is not native to the
place or area where it is considered introduced and
instead has been accidentally or deliberately
transported to the new location by human activity.
UNINTENTIONAL
INTRODUCTION
 Migration due to Climate Change.
 Sea water released from ship ballast.
INTENTIONAL
INTRODUCTION
 The disposal from Aquariums.
 The Exotic Pet Trade
CATEGORIES OF EXOTIC
SPECIES
Invasive-
Non Invasive-
INVASIVE SPECIES
An invasive species is one that has been
introduced and become a pest in its new
location, spreading (invading) by natural
means.
LIONFISH INVASION
 There have been a reported 68 different invading
marine species found throughout Florida, the Caribbean,
and the Gulf of Mexico over the last century according to
the U.S. Geological Survey, but none have wreaked as
much havoc on the marine environment as the voracious
red lionfish that devour native fish populations wherever
it invades.
Lionfish have no known predators because they
do not belong in these waters. There is nothing here
to eat them, and nothing to stop them from
consuming all of Florida’s and Caribbean reef fish.
Now they are breeding at a pace so rapid that
scientists are feverishly trying to fight the invasion.
To do this they are studying and collecting the
lionfish, trying to eliminate a species now found in
deep as well as shallow waters.
LOSS OF HABITAT
When humans overexploit environmental resources that are used
by other organisms to sustain their life, it will result in that
organism’s habitat being destroyed after resources are used up.
LOSS OF HABITAT
In all the factors influencing overconsumption in developing
and developed countries it all comes down to one
consequence. This is the LOSS / DESTRUCTION OF ONES
HABITAT, whether it belongs to human beings, animals or
plants.
