this presentation is about the sustainability of the environment and techniques we can use to preserve our Environment for future generation along with statistics.
4. • Population growth
• Wasteful and unsustainable resource use
• Poverty
• Failure to include environmental costs of goods and services in
market prices
• Too little knowledge of how nature works
• People with different environmental worldviews often disagree
about the seriousness of environmental problems and what we
should do about them.
Causes Of Environmental Problems
9. • Environment is every thing that effects
living organisms.
• Ecology is biological science that studies
relationship between living organisms and
their environment.
What Is Environment?
10. • In ecology, sustainability is how biological systems
remain diverse and productive. Long-lived and healthy
wetlands and forests are examples of
sustainable biological systems. In more general
terms, sustainability is the endurance of systems and
processes.
What Is Sustainability
13. Sustainable Yield: the highest rate at which a renewable
resource can be used without reducing its supply.
Example: over-farming the land leading to soil erosion,
clear-cutting forests.
Environmental Degradation: when we exceed the natural
replacement rate of the resource.
Example: groundwater depletion, water pollution
Renewable Resources
(can be depleted or degraded)
14. Degradation of renewable free-access
resources.
“If I do not use this resource, someone else
will. The little bit I use or pollute is not
enough to matter, and such resources are
renewable anyway.”
Solutions?
Tragedy of Commons
15. • Exist only in fixed quantities on earth.
• Metallic resources (iron, copper, aluminum)
• Non-metallic resources (salt, clay, sand)
• Energy Resources (coal, oil , natural gas)
When 80% is gone
It may be too
Costly to get last
20%.
Non-Renewable Resources
16. Reduce: Use less resource
Reuse: To use the resource more than once
to conserve.
Recycle: collecting resource, processing it
into new products.
Saving non-renewable resources
18. What is an Environmentally Sustainable
Society
• Our lives and economies depend on energy
from the sun (solar capital) and natural
resources and natural services (natural capital)
provided by the earth.
• Living sustainably means living off earth’s
natural income without depleting or degrading
the natural capital that supplies it.
19. How an environmentally sustainable society
grows economically
• Societies can become more environmentally
sustainable through economic development
dedicated to improving the quality of life for
everyone without degrading the earth’s life-
support systems.
20. Four Scientific Principles Of Sustainability
• Nature has sustained itself for billions of years
by using solar energy, biodiversity, population
regulation, and nutrient cycling – lessons from
nature that we can apply to our lifestyles and
economies.
24. Sustainable Park System in Oregon
• Oregon Sustainable Parks are designed,
developed and operated to promote a
sustainable future meeting the needs of today
without compromising and by balancing the
economic, social and ecological needs of future
residents.
25. Sustainable Park System in Oregon
Sustainable Parks will:
• Support a stable and diverse economy
• Protect and enhance the quality of the air, water, land
and other natural resources
• Protect and enhance native vegetation, habitat areas,
fish and wildlife
• Create opportunities for enhanced social benefits
• Build community
• Promote stewardship and educate the public about
sustainability
• Result in more cost-effective park management
practices
• Ensure longevity of parks and recreation facilities
27. Cactus Dish Washer
• Providing A class washing performance for dishes with
minimum water and energy consumption in order to
leave a better world for future generations.
29. Painted Wood Coffee Table
• sustainable, unique and contemporary small square
coffee table with drawer.
• Manufactured from recycled wood, it is both stylish and
fully sustainable. The top of the coffee table and the
front of the drawer have both been hand painted.
30. .
The main idea is that we must act responsibly so
that resources on the planet will be able to
support many generations to come.
