Chapter 1 Flashcards
What are some statistics of Increasing population growth and declining human well-being?
Population growth: 80 Mil per year
- 2013-over 7.1 Billion
- 2050-could be 9.3 Billion
- 2200-10 billion
What are Four Global trends that are of particular concern?
1) Increasing Population Growth and Declining Human Well-Being
2) A decline of vital ecosystem services
3) The negative impacts of global atmospheric changes
4) A loss of biodiversity
All UN member countries adopted a set of goals to reduce poverty and it’s effects on human well-being
Millennium Goals
What are 4 Indicators of Decline of Vital Ecosystems?
- Depleted Water Supplies
- Degraded Agricultural Soil
- Overfishing
- Forests cut faster than they grow
The natural and managed ecosystems that provide essential goods and services to human enterprises.
Ecosystem Capital
3 types of goods and services
1)PROVISIONING Services:goods like food and fuel
(timber,fiber,crops,livestock,wild foods,etc.)
2)REGULATING Services:processes like flood protection(erosion pro.)
3)CULTURAL Services:Nonmaterial benefits like Recreation.
Goods
Freshwater,all of our foods,much of our fuel,wood for lumber and paper,leather,furs,raw materials for fabric,oils and alcohol,etc.
Services
Support human life and economic well-being,such as the breakdown of wastes,regulation of the climate,erosion control,pest management,crucial nutrient cycles.
Took 4 years to compile information about the ecosystem around the globe.Scientists found widespread abuse and overexploitation of ecosystem resources
Millennium Ecosystems Assessment
Global Warming trend since 1958 correlates with the emissions of CO2
280 ppm-1990,395 ppm-2012
Greenhouse effect-increase in the temperature caused by Co2 and other gases to trap heat.
Anthropogenic greenhouse gases
Due to human activity
What is an unavoidable by-product of burning fossil fuels?
CO2
Fossil Fuels-like crude oil,coal,and natural gas
The Intergovernmental Panel on Climate Change(IPCC)
-responsibility to report it’s Assessment on climate change at 5-year intervals.
The Fourth Assessment Report (FAR)
-produces convincing evidence of human-induced climate change
Montreal Protocol (1987)
-aimed at curbing pollution from the release of
chlorofluorocarbon refrigerants into the atmosphere
Kyoto Protocol
- 166 nations met in Kyoto Japan in December 1997
- Treaty was ratified in 2004 to reduce emissions of CO2 and other greenhouse gases
- US-biggest emitter
What is Biodiversity and what significance does it serve?
They variability among living organisms and the ecological complexes of which they are apart
- It’s the mainstay of Agriculture Crops and Medicine
- Critical Factor in maintaining the stability of natural systems
- Enabling them to recover after disturbances
What are 3 Contributors of Loss of Biodiversity?
- Habitat Alteration
- Pollution
- Exploitation
What is the study of how the world works? It is the most multidisciplinary of all the sciences.
Environmental Science
What are the Cumulative Impacts?
Doing too much of one activity
What are the Un-intended Consequences ?
Not paying attention how the world works
What is the movement that is marked by increasing awareness of the environment. It has been so successful that Congress created the Environmental Protection Agency (EPA) in 1970 and passed numerous laws promoting pollution control and wildlife protection?
The Environmental Movement
What are persons and organizations with a strong focus on environmental concerns?
Environmentalists
What is a term used to refer to the widespread development of the environmental movement?
Environmentalism
What are the Strategic themes of how we should conceptualize our task of forging a sustainable future?
- Sound Science
- Stewardship
- Sustainability
What is the basis for our understanding of how the world works and how human systems interact with it?
Sound Science
