5
Industrial Machines Advanced technology Factories Increase in population Increase in pollution
6
Sustainable Development Ethic Resources are limited Humans are part of nature
7

Fossil Fuel Fuels from the remains of organisms that lived long ago (fossils) Ex: coal, oil, gas
26

27
Petroleum Liquid Formed from aquatic microorganisms, sedimentation, heat and pressure
28
Natural Gas Formed from aquatic microorganisms, sedimentation, heat and pressure (same as petroleum)
29
Fracking Fracturing shale rock with a pressurized fluid to release petroleum or natural gas
