oxygen, wood, water, sunlight, wind

Question 3

nonrenewable resources 3

Answer 3

• consumed quicker than it can be created

fossil fuels, metal, plastic

Question 4

technology pollutes 3

Answer 4

air water land

Question 5

Technology provides 3

Answer 5

clean energy
waste management
cleanup pollution

Question 6

3 types of technology that influences sustainability

Answer 6

agriculture, alternative energy, industrial

Question 7

agricultural goal

Answer 7

increase food yields

Question 8

agricultural pros 4

Answer 8

contour farming (prevents soil erosion)

fertilizer (increase yields from more soil nutrition)

Irrigation system (drip irrigation). prevents soil errosion, improve effieciency

farming machines

Question 9

agricultural cons 2

Answer 9

fertilizer = excess nitrogen eutrification

farm machines use fossil fuels- pollution

Question 10

alternative energy goal

Answer 10

provide clean energy to power society without influencing atmosphere

Question 11

alternative energy pro 2

Answer 11

decrease bruning fossil fuels
use renewable resources (sunlight, wind, water, nuclear)

Question 12

alternative energy con 2

Answer 12

expensive (+uses fossil fuels to create the structures)

nuclear energy creates radioactive waste

Question 13

industrial tech goal

Answer 13

increase manufacturing efficiency, transportation, and communication

Question 14

industiral tech pro 3

Answer 14

improve communication
fast transport
cheaper industries

Question 15

industrial tech con 2

Answer 15

creates CFC (foam packaging material + refrigerants)

burn offil fules=increase greenhouse gasses + acid rain

Question 16

acid rain

Answer 16

takes/ leaches soil nutrience
changes water pH

Question 17

CFC

Answer 17

clora flora caarbons

depletes ozone layer

Question 18

greenhouse effect

Answer 18

NORMAL/NATURAL warming effect when gasses trap heat in atmosphere

Question 19

greenhouse gasses 4

Answer 19

CO2
O2
CH4 (methane)
H2O

Question 20

global warming

Answer 20

CFCs deplete ozone layer=more suns UV rays to get in

key contributor: combustion

• CO2 into air more greenhouse gases = up temperature of earth

Question 21

biodiversity

Answer 21

higher biodiverity = healtheir ecosystem

Question 22

human impact

Answer 22

pollution
habiitat destruction/fragmentation

introduce new disease, invasive species
- water hyacinth
