Methaneemissions also result from the decomposition of organic wastesin municipal solid waste landfills, and the raising of livestock. Nitrous oxide agricultural and industrial activities, as well as duringcombustion of solid waste and fossil fuels. Hydro Fluoro Carbons (HFCs),Per Fluoro Carbons (PFCs),Sulphur HexaFluoride (SF6), industrial processes. 10. Example of theGreenhouse EffectThe Suns energypasses through thecars windshield.This energy (heat)is trapped insidethe car and cannotpass back throughthe windshield,causing the insideof the car to warmup. 11. 11EffEcts Health Water resources Mountains Forests Deserts Coastal Zones Agriculture International 12. Households are Big Contributors to Climate ChangeOf all greenhouse gasemissions come fromhouseholds: Vehicles Home Heating Electricity 13. so how can Each of usslow global warming now? 14.
