Global Environmental Trends World Resources Institute

Global population continues to rise

Stabilization remains a challenge

Different assumptions, different projections

Fertility declines, real and projected

Rapid growth in low income economies

The number of poor continues to grow

Growing disparities in incomes among regions

Urban Growth Spurt Continues

Africa and Asia are Urbanizing Fastest

People on the Move

Progress Toward Democracy OECD: Organisation for Economic Co-operation and Development

More Children Are Attending School

More Adults Can Read

Yield (metric tons/hectare) Wheat Yield Rice Yield Maize Yield Yields Are Up, But Growth is Slowing

% Increase in Yield WheatPaddy RiceMaize Yields Are Up, But Growth is Slowing

Progress in Feeding the World Has Varied Widely by Region

Despite Gains, Millions Go Hungry

World Totals (million hectares) Vegetation Removal579 Overexploitation133 Overgrazing679 Agricultural Activities522 Industrial and Bioindustrial 23 Degraded Soil Means Less Food

Food Supply Increasingly Relies on Irrigation

Farmed Fish Are a Growing Share of the Global Fish Harvest

What Do Industrial Economies Use?

Paper Use is Growing Worldwide

Paper Recycling: Rising Volume, Growing Importance

Vehicle numbers are rising dramatically

Motor vehicle use is highest in developed countries

Surface temperatures have warmed over the past century Temperature (Fahrenheit)Temperature (Celcius)

Greenhouse gas warming

Per capita CO 2 emissions are small in developing countries (metric tons of carbon dioxide)

Developed nations have altered the atmosphere most

Stabilizing CO 2 means steep emission cuts eventually

Success story: CFC production has fallen sharply

Backsliding: Halon production is rising again

Excess nutrients may spur algal blooms Pre 1972

Excess nutrients may spur algal blooms Post 1972

More fertilizer: More food, but more pollution too

SO 2 emissions in Asia could triple

NOx levels are still a problem in Europe and North America

Forest Loss Is Severe in the Tropics

Amazon Deforestation Remains High

Many of Earth’s Forests Have Been Cleared or Degraded

Water Demand is Growing, But Supplies Are Limited

Agriculture Dominates Water Use, But Its Share Will Decline

Low-Income Nations Are Especially Vulnerable to Water Scarcity

River Habitats Have Been Heavily Altered

How Much Are Nature’s Services Worth? Global GNP (US $18 trillion) Ecosystem Services (US $33 trillion) Ecosystem Services (US $33 trillion)

Reef Threats Are Extensive

Some Fish Stocks Have Collapsed from Overfishing COD CATCH NON COD CATCH

Bird Populations Are Under Siege Worldwide
