What is Economic Growth? www. assignmentpoint. com

Economic growth is an increase in the capacity of a country to provide people with goods and services. Must have more people (producers and consumers) and more production and/or consumption person. www. assignmentpoint. com

Apply gross domestic product (GDP) and per capita GDP in determining economic growth. Gross domestic product (GDP)- a way to measure the economic growth (% change in GDP/ country) Encompasses the annual market value of all goods and services produced, foreign and domestic, operating within a country. The higher the GDP, the faster the economic growth. per capita GDP-changes in a country’s economic growth person or GDP/population at midyear How do you think the GDP and per capita GDP compare for developing nations versus developed nations? www. assignmentpoint. com

Developed countries (US, Japan, Canada, Australia, Europe): highly industrialized and have a high per capita GDP, Use most of Resources, create most waste and pollution, have most money www. assignmentpoint. com Developing or moderately developed countries (Africa, Asia, Latin America, China, India, Brazil, Mexico): low per capita GDP (either have high GDP but so many people it brings down per capita GDP (China) or low GDP because they are a poor country (Africa), have less money, use less resources, cause less waste and pollution

Overview of major environmental problems: Environment al Problem Coral reef loss Cause Water temperature increase Forrest shrinking Atmosphere warming Fisheries collapse Groundwater pollution www. assignmentpoint. com Effect on humans Losing aesthetic value, storm buffer, fish habitat Prevention method Decrease the amount of greenhouse gases released Remediation Protect reefs, help rebuild

Major Causes Population growth Wasteful use of resources Affluenza Poverty Poor environmental accounting Environmental ignorance Global trade policies that undermine environmental protection Money in politics Failure of those concerned about environmental quality to provide positive visions of more sustainable economic and environmental futures (unattainable goals) 3 things that have the greatest environmental impact: agriculture, transportation, heating and cooling buildings. www. assignmentpoint. com

How and why did the agricultural and industrial revolution affect human population size and the environment? HOW Agricultural revolution (1900’s) Increase WHY Industrial revolution Increase www. assignmentpoint. com ENVIRONMENTAL IMPACTS Introduction of Machines (plow, cotton gin, combine) More food Freed more people to do different kinds of jobs More pollution and wastes, natural resource use went up Factories, trains (coalburning), steamships, ironworks More pollution (CO 2, NOx, SOx) and wastes, natural resource use went up

Pollutants are chemicals at high enough levels in air, water, soil, or food to threaten the health, survival, or activities of humans or other living organisms From natural occurrences- volcanoes From man-driven actions- burning coal Effects of pollution: Can degrade life-support systems for humans and other species. Damage wildlife, human health and property Create nuisances like noise and unpleasant smells, tastes, sights Solutions: Prevention (costs more up front, research is needed to www. assignmentpoint. com have new technology) and cleanup (cause pollution somewhere else, expensive)

Point sources single, identifiable sources like smokestacks on coal-burning plants or exhaust pipe of a car Nonpoint sources larger and dispersed sources like pesticides blown into the air and carried by wind, runoff of fertilizer from farms, golf courses, and lawns in streams and lakes. www. assignmentpoint. com

What does p. H measure? What is the p. H equation? What is the p. H scale? Hydrogen ion concentration [H+] p. H= -log[H+] = [H 3 O+] p. H=1 : [H+]=1 x 10 -1 moles/liter (acidic) If you have a solution with 1 x 10 -6 and a solution of 1 x 108 [H+], how much more acidic is one than the other? www. assignmentpoint. com

Buffers stop drastic changes in p. H by reaching equilibrium and forming the conjugate base. www. assignmentpoint. com

What is a NOx? They are mono-nitrogen oxides NO and NO 2 (nitric oxide and nitrogen dioxide). They are produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures. Produce smog and acid rain NOT to be confused with N 2 O (nitrous oxide) which is a greenhouse gas (absorbs and emits radiation) www. assignmentpoint. com

What is a SOx? • Sulfur oxide gases • SO 2, SO 3 • These gases dissolve easily in water to form acid rain • SOx gases are formed when fuel containing sulfur, such as coal and oil, is burned, and when gasoline is extracted from oil, or metals are extracted from ore. www. assignmentpoint. com

What is a VOC and give 3 examples. Volatile organic compound Methane (CH 4), Benzene (C 6 H 6), paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, office equipment such as copiers and printers, correction fluids and carbonless copy paper, graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions. www. assignmentpoint. com
