Environmental Science (Bio-220)(GCU)
Environmental Science
is the systematic study of our environment and our place in it
Interdisciplinary:
1. Natural Sciences
2. Social Sciences
3. Humanities
Energy:
fossil fuel use causes pollution, there is a shift to using more renewable energy resources.
Biodiversity Loss
species are being lost at a rapid rate.
Air Pollution
air quality has worsened dramatically in many areas.
Agriculture
Expanded food production led to increased population and consumption
What are Scientists have firmly concluded that humans are changing the composition of ?
atmosphere
What happens when Earth's surface is warming?
Melting glaciers
Rising sea levels
Impacted wildlife and crops
Increasingly destructive weather
Population & Pollution
Many cities are more livable today than a century ago due to human birth rate stabilization and
clean technology use.
Health
Incidence of life-threatening diseases has been reduced in most countries.
, Information and Education
Expanding access to knowledge is essential to progress.
Sustainable Resource Use and Habitat Conservation
Tropical forest destruction has slowed & habitat protection has improved in some areas.
Renewable Energy
Progress is being made in the transition to renewable energy sources.
Carbon Markets and Standards
Cap-and-trade programs help limit greenhouse gas emissions.
International Cooperation
Some international environmental protection agreements have been highly successful, while
others lack enforcement.
Who is this?
~Man and Nature published in 1864
~Influenced Theodore Roosevelt and his conservation advisor,
~"For the greatest good for the greatest number for the longest time"
~Reflected today in the Multiple Use Policies of USFS
George Perkins Marsh
~President Sierra Club
~Nature deserves to exist for its own sake - regardless of degree of usefulness to humans.
John Muir
Biocentric Preservation
"Why ought man to value himself more than...the one great unit of creation." He opposed
Pinchot's view.
Aldo Leopold
~A student of Pinchot's
~Authored "The Land Ethic" - "we abuse land
because we regard it as a commodity belonging
to us."
