Which statement best explains an environmental outcome of using fossil fuels for energy?
Fossil fuels release carbon dioxide which plants use to make food
When fossil fuels are bumed they release toxic gases into the air that cause pollution and increase global
warming
When fossil fuels are bumed, hazardous ash is created and carried through the environment by wind and
dropped into nearby lakes and ponds
Fossil fuels produce waste that exposes humans to dangerous levels of radiation
