1. SUSTAINABLE USE OF
ECOSYSTEM
For sustainable ecosystem, we have to make
globe green

2. SUSTAINABILITY
1. The ability to maintain ecological
processes over long periods of
time.
2. Sustainability of an ecosystem is
the ability of that ecosystem to
maintain its structure and function
over time in the face of external
stress.

3. SUSTAINABILITY
Is strongly linked to ecosystem health. The more sustainable an
ecosystem is, the healthier it is because it is able to “deal” with
external stress better i.e. limiting factors.

4. ECOSYSTEM AND SUSTAINABILITY
• The biodiversity of an ecosystem contributes to the
sustainability of that ecosystem.
Higher/more biodiversity = more sustainable
Lower/less biodiversity = less sustainable
• High biodiversity in an ecosystem means that there
is a great variety of genes and species in that
ecosystem.

5. HOW DOES AN ECOSYSTEM BECOME SUSTAINABLE ?
 By having a lot of biodiversity.
 The biodiversity of an ecosystem contributes to the sustainability of
that ecosystem.
 The higher the biodiversity of an ecosystem, the more sustainable it
is.
 Conversely, lower biodiversity equals less sustainability.

6. MAJOR ENVIRONMENTAL PROBLEMS
 Air pollution
 Biodiversity depletion
 Water pollution
 Waste production
 Food supply problems

7. AIR POLLUTION
 Global climate change
 Stratospheric ozone depletion
 Urban air pollution
 Acid deposition
 Outdoor pollutants
 Indoor pollutants
 Noise

8. BIODIVERSITY DEPLETION
 Habitat destruction
 Habitat degradation
 Extinction

9.  Sediments
 Nutrient overloaded
 Toxic chemicals
 Infectious agents
 Oxygen depletion
 Pesticides
 Oil spills
 Excess heat
 Solid waste
 Hazardous wastes
Water problems Waste production

10. FOOD SUPPLY PROBLEMS
 Overgrazing
 Farmland loss and degradation
 Wetland loss and degradation
 Overfishing
 Coastal pollution
 Soil erosion
 Ground water depletion
 Soil water logging
 Soil water shortage
 Loss of biodiversity

11. HOW TO INCREASE THE SUSTAINABILITY?
 Recycling, reusing, caring for the environment (planting,
etc.), taking only the surplus of populations when fishing
or hunting, reduce pollution, etc.
 The main idea is that we must act responsibly, so that
the resources on the planet well be able to support
many generations
