1. “The US Role in Global Population-Environmental Links” AAAS Annual Meeting

2. I.US role in global context (high population growth and resource use) II.Key US population factors and environmental impacts III. US population/RH trends IV. New research on env/pop as tool to address issues

3. Global population and environmental changes are occurring in fundamentally different ways than ever before in history 60% of earth’s ecosystems transformed, mainly from human activity (UN Millennium Ecosystem Assessment) More people on earth than ever before (LDCs, urban, young, aging)

4. Plays out differently in various world areas: Local village/community level National/country level * Global level *US case – Combination of high population growth and resource consumption

6. The US Role in the Global Context Disproportionate 5% of world population, consuming over 25% natural resources US is the largest, fastest growing of the industrialized nations Only one experiencing significant population growth Combination (high population growth and high per capita resource use) results in biggest environmental footprint globally

8. US Population Factors Linked to Environment Population size and growth rate Distribution Composition (age, income, etc.) Households (number, size, land) Per-Capita consumption of natural resources

9. Households Three way impact: Decrease in number of people per household (increase in number of houses) Increase in average house size Increase in land area around homes

10. Key US Population Trends Linked to Environment Rural to urban Past hundred years - largest population increase (doubled since 1950) Density doubled Shifts to South and West

11. “Metropolitanization”/ sprawl Over 51% live in coastal areas, on 1/5 land area Population-Environment “Hot Spots” - Coastal ecosystems in South; - Water issues in West (largest and fastest growing US regions)

12. Main US Population-Environment Linkages Land Use: each American uses 20% more land for multiples uses than 20 years ago. Water: US is top ten in world use per capita, uses 3 times world average - 40-50% rivers/lakes too polluted for swimming/fishing - 53% wetlands lost from development or agriculture use

13. Forests: US is largest world consumer of forest products Biodiversity: 6,700 plant and animal species at risk from extinction in US, mainly from habitat loss. -Half US land no longer supports original vegetation; sixth mass extinction, first time attributed to humans

15. Energy: 5% population, 25% energy consumed; highest world oil consumer; transportation fastest growing energy use sector Climate Change: 2 nd largest CO2 emitter; 25% of world emissions; temperature increases of 5-9 F in 100 years/SLR and severe weather in coasts (NH=NC)

18. Fisheries: 30% of US coastal fish populations overfished; one third of all US lakes, quarter of rivers, two thirds of the coastline’s fish under advisory from mercury; third of US freshwater animal species “at risk” Waste: Each American produces 5 times average of developing nations per capita

19. US Population 3 rd largest country in world Largest and fastest growing of all industrialized nations (add 7,200 day) - 1/3 immigration - 2/3 natural increase*

20. Addressing US Population – RH Trends Nearly half of pregnancies in US are unintended (at least 38% of pregnancies in every US state are unintended). The rate has increased substantially among poor and low-income women, while declining among higher- income women. Most unintended pregnancies (95%) due to women using contraception inconsistently, incorrectly, or not at all for a month or more during the year.

21. Nearly half of pregnancies in the United States are unintended Source: Guttmacher Institute 2011

22. Most unintended pregnancies occur when women fail to use contraceptives or use their method inconsistently

23. What do Americans/environmentalists think about population? New Survey/polling research (Americans for UNFPA) Best entry point: women’s empowerment New constituency: concerned about environmental degradation, believe population/consumption = negative env. impact Contraception can make a big difference in slowing population growth Environmentalists ready to discuss population and favor addressing it through voluntary access to contraception

24. Current Status = Future Status? on US/Global “RH, development, environment issues” I. Choice: Reproductive health and sustainable consumption - Youth key II. Access: Need to have universal access to good quality reproductive health

25. Socolow/Pacala’s “stabilization wedge” to reduce CO2 emissions. Population stabilization can be 1-2 wedges.

26. What Works, What’s Possible Interdisciplinary, science-based solutions Women/girl-centered approaches -Impacts, solutions (voice, leadership) -Different DC/LDC US roles and responsibilities (US leadership in funding and support RH; girls/women’s empowerment/opportunities; education; environmental sustainability US and globally )
