The world population has grown rapidly and exceeded the Earth's carrying capacity, causing issues like depletion of natural resources, environmental problems, water scarcity, destruction of rainforests and fisheries overexploitation. By 2050, the world population is projected to reach at least 9 billion people, which will increase the demand for food and fuel and likely outpace food production. This unsustainable population growth threatens our planet's life support systems and risks exacerbating problems like global warming, extreme weather, and loss of biodiversity if no action is taken to transition to a greener economy and more sustainable consumption and production.

outstripped the capacity of the
world to support
world population

Green Economy
 Sustainable consumption and
production
 The world we want

to sustain a Green Planet

4. Lu Liu
World Population Reaches 7 Billion
Overpopulation is an undoubtable
facts which far exceeds the carrying
capacity of our earth .

Depletion of Natural Resources

“Do We Consume Too Much?”
“Do We Fit On the Planet?”
“By the 2030s, we
will need the
RESOURCES of
two Earths to
support us. But we
only have one.”

7. The Shortage Of Land Leads
Over-Crowed Cities
Lu Liu
City environmental problems, such as air pollution,
inadequate water ,waste management and so on.

8. Urban problems
-Greater Los Angeles
Greater Los Angeles is able to
support at most one million people
on its own water system and
energy supply; as of 2015, There
are population of over 18 million.
Actually the similar resource
scarcity will happen in most cities
as the world population increases
Lu Liu

9. Water Scarcity
Lu Liu
“By 2025, 1.8 billion people will be
living in countries or regions with
absolute water scarcity”
%50 Developing
country
“and two-thirds of the
world population could live
under water stress
conditions.”

10. Tropical Rainforest
Lu Liu
Destroyed at 100
acres /minute
2%
EARTH
“Covering less than 2 percent of the Earth's total surface area, the
world's rainforests are home to 50 percent of the Earth's plants and
animals.”
Data:http://www.nature.org/ourinitiatives/urgent
issues/rainforests/rainforests-facts.xml

11. World’s Fisheries
Lu Liu
Consumed too much
72%
“Of the 600 marine fish stocks monitored by FAO, 52% are fully
exploited, 17% are overexploited, 7% are depleted. ”

12. World Footprint
Lu Liu
To keep up with human
consumption by 2050

PLANET
Today People uses the about 1.5 planets to provide the resources
we use and absorb our waste.

13. Global Carbon Emissions
Lu Liu
from 1900-2008
16
Times
“Global carbon emissions from fossil fuels have significantly increased
since 1900. Emissions increased by over 16 times between 1900 and
2008 and by about 1.5 times between 1990 and 2008.”
Data:http://www.epa.gov/climatechange/ghge
missions/global.html

14. World population At least 9 billion people in 2050
The demand for food and
fuel
Likely outpace food production
Increased use in
agriculture
Reducing water resources ,add more climate
change
Food Could Be Most Serious
Global Issue By 2050
Lu Liu

15. Global warming
Extreme weather events that
threaten our life
One-third of all counties
Facing sustainability of water supplies in the
future
50% carbon emissions Leading Sea level being risen and forest loss

16. “Population Matters”
Lu Liu
Data http://blog.populationinstitute.org/

17.  Different View About
Over-Population
☑ We have enough food ,forest
and renewable resources to
feed 10 billion people .
Lu Liu
☑ Farmers worldwide could
double the crop production

18.  Different View About
Over-Population
“No global shortages of natural fuels are in
sight.” (“Consumption: Theory and issues in the study of consumption” Daniel Miller
Taylor & Francis, Jan 1, 2001)
 “Technologies are ready to begin building
a world energy system powered by solar
resources.”

Inspire our solutions and innovations
awareness of Environmental Stewardship
& Sustainability.

20. Problem Worth Solving
☑ Environment Sustainability
☑ Reduce Poverty And
Inequality
☑ Protect Our Planet
☑ Biodiversity Conservation
Lu Liu

21. Renewable
Energy
Lu Liu
Stop fossil fuels which puts
Our lands, air,
water and climate at risk.

22. Conserving Fisheries
 Ocean ecosystems will continue to
deteriorate by overfishing and pollution.
 Sustainable fishing by conservation-
minded fishing practices.

24. Reach zero loss of natural
habitats
Establish a conservation
target of 17% water areas
Restore at least 15% of
degraded areas
Some Biodiversity Targets

25. Conclusion
Our Planet Cannot Support
Our Population Growth
 The global eco - system is damaging
under more than 7 billion people.
 It is not possible to support still
growing exponentially population.
Lu Liu

26. Continued
 Earth has lost 80,000 acres forest
every day, some 50,000 species a year,
and many clean air ,water and land.
 How can we feed more people without
doing bad the earth?
Lu Liu

27. Take Action --Sustainable
Development
Lu Liu
Meet the needs
of the world's current
population without
damaging our
Planet

28. Take Action --Stewardship
Priorities

Safeguarding ecosystem
Reduce the direct pressures on
biodiversity
Sustainable consumption and
production
Protecting endangered animals
