APES: Chapter 1 What is Environmental Science? What are resources? What is pollution?
What is Environmental Science? Environmental Science - interdisciplinary study of human relationships with other organisms and the nonliving physical environment
Watch This! Mercy Mercy Me - Marvin Gaye 1971 : What’s Going On Album
What is the study of Env. Science ? Environmental Science tries to establish principles and model how the natural world functions AND THEN uses these principles to develop solutions to environmental problems caused by humans.
What is a resource? Resource - anything from environment that meets the needs/wants of humans defined based on replenishment time
Renewable Resource replenished during lifetime, can be depleted but regenerated in human lifespan
Nonrenewable Resource Cannot be replenished during lifetime, fixed stock, can be replenished on geologic timescale
Perpetual Resource Renewed Continuously
Ecological Footprint Amount of land needed to produce the resources needed by an average person in a country
Ecological Footprint
Sustainable Meeting the needs of today without harming future generation’s abilities to meet their needs.
Three Principles of Sustainability
Sustainable
Solar Capital Natural Capital What needs to be sustained?
Natural Capital = Natural Resources + Natural Services Fig. 1-4, p. 9
What is pollution? Pollution -any addition to air/water/food/soil that threatens health of organisms
Sources Point Source from single identifiable source Nonpoint Source from dispersed sources p. 12 = Fig 1-9, Fig 1-10 Env. Problems + Causes
Major Environmental Problems 1.Air Pollution 2.Biodiversity Depletion 3.Food Supply Problems 4.Waste Production 5.Water Pollution
Basic Causes of Environmental Problems 1.Rapid Population Growth 2.Unsustainable Resource Use 3.Poverty 4.Not including environmental cost in the price of goods/services 5.Trying to manage and simplify nature with too little understanding of how it works.

IPAT is Another Environmental Impact Model I = P x A x T – I = Environmental impact – P = Population – A = Affluence – T = Technology
Environmental Impact of Humans
Fig. 1-14, p. 17 Less-Developed Countries Consumption per person (affluence, A) Population (P) Technological impact per unit of consumption (T) Environmental impact of population (I) More-Developed Countries
What are current issues at the heart of Env. Science? ENERGY SUPPLY and DEMAND GLOBAL WARMING
OVERPOPULATION FOOD SUPPLIES
