Date: ______Living Environment Unit 9 Human Impact Study Outline Test Date: ______Unit 8 Important Topics:

I. Aim # 55: Nonrenewable vs. Renewable Resources

II. Aim # 56: Water Pollution

III. Aim # 57: Global Warming and Ozone Depletion

IV. Aim # 58: Human Interference & Decision Making

KNOW THAT HUMAN POPULATION IS INCREASING DRASTICALLY ….

WHICH IS NEGATIVELY IMPACTING THE ENVIRONMENT

KNOW THE TYPES OF RESOURCES USED TO GENERATE ENERGY

Type of Resource Definition Example Positives Negatives Resources that cannot Fossil Fuels-Coal, oil, - cheap - cannot be be replenished within a and natural gas - easily found replenished once lifetime. They exist in - provides us gone - release CO2 limited (finite) with energy Non renewable which leads to amounts global warming

Resources that can be Wind power, water -Renewable (will -Expensive replenished within a power, solar power, not run out) geothermal power, lifetime. -Less Pollution Renewable biofuels

ECOLOGICAL CAUSE NEGATIVE SOLUTION PROBLEM EFFECT

 Development of  Increases use of  Use cleaner technologies/alternative Factories, Cities, resources, human energy sources Industrialization etc. population, &  Pass laws to regulate development of pollution factories  Acid rain, global warming  Habitat loss  Burning fossil  Acidification of  Buffers to neutralize lakes & rivers fuels releases lakes and soil  Use filters on smokestacks Acid sulfur and • Damages  Use alternative energy sources to reduce Rain nitrogen into the wildlife/plants the burning of fossil fuels • Increases erosion air. on buildings  These gases + rain = acid rain.

 Increase of  Changes in  Use alternative energy sources (solar, greenhouse gases climate/weather wind, hydroelectric) (MAINLY CO2 which can lead to Global and methane) due loss of  Decrease burning fossil fuels (reduce, Warming to burning fossil habitats/species reuse, recycle) fuels (which releases CO2)  Plant trees

 Decrease deforestation  Deforestation prevents producers from naturally removing CO2 from atmosphere during photosynthesis  CFCs  More harmful UV  Don’t use CFC’s/ban them Depletion of the (Chlorofluorocarb rays reach Earth’s  Use safer chemicals Ozone Layer ons) which are surface = increase released by in mutations and aerosols, air conditioners, skin cancer refrigerator coolants

 Deforestation • Loss of  Pass laws to protect natural areas (natural biodiversity parks, preserves etc.) Loss of Habitats  Industrialization • Loss of potential  Control population growth resources (ex:  Farming Medicine from the rainforest) • Unstable ecosystems  Habitat Loss • Unstable  Regulate hunting Loss of ecosystems  Overhunting • Loss of  Pass laws to protect species Biodiversity genes/organisms  Overfishing • Loss of medicines/resourc es

 Humans moving  They have no • Control/restrict importation of goods Invasive (imported around the planet natural predators • Set traps that use chemical scents to attract causes organisms  Overcrowd and insects or foreign) • Control the population by releasing to be brought to outcompete native Species species. biological controls = releasing natural new habitats that diseases/predators if that species lack their natural predators (ex: Purple loosestrife plant, gypsy moth, zebra mussels, Japanese beetle)

Station # 1 Human Impact Station Review

Station # 2

Some scientists are urging that immediate action be taken to stop activities that contribute to global warming. Discuss the effects of global warming on the environment and describe some human activities that may contribute to it.

Your answer must include

: • an explanation of what is meant by the term global warming

• one human activity that is thought to be a major contributor to global warming and an explanation of how it may contribute to the problem

• one negative effect of global warming if it continues for many years
