My car
& the environment
When I drive my car with no other passengers, 95% of the energy goes into moving the 1,450 kilo car not in carrying me, its 64-kilo driver.
My car contains 800 kilos of steel, 180 kilos of iron, 112 kilos of plastics, 86 kilos of fluids, 85 kilos of aluminium and 62 kilos of rubber.
Nearly half the steel that was used to make my car began as scrap. The scrap was melted in a furnace, which produced eight pounds of toxic dust.
The rest of the steel came from a much dirtier place an open pit mine in the forests of Minnesota. A total of 1,590 kilos of iron ore was mined to make my car. This produced 955 kilos of waste rock which was dumped.
When the ore was made into steel , coke was used. As the coke burns, it produces carbon monoxide and carbon dioxide.
SCRAP: used materials collected to be used again.
FURNACE: a place with very high temperatures used to melt metals.
TOXIC DUST: poisonous dirt.
OPEN PIT MINE: a mine where minerals come from large open holes dug on the surface.
If you DUMP something, you get rid of it as waste.
COKE: a black or grey substance produced from coal that is burned to make heat.
When my car was assembled, the process used nearly 150,000 litres of water that is more than 100 times the weight of the car.
My car's body was then painted in Detroit, where it was dipped into baths of detergent, zinc phosphate and chromic acid. Next it was submerged in a chemical that pollutes the air, to prepare it for painting. Then it was baked. After that, the car was painted by spraying it six times with a paint that includes PVC solvent.
The waste paint from the spraying process cannot be used again. It was taken to a landfill and buried.
SUBMERGE: to go down into a liquid.
PVC: Polyvinyl chloride - a type of plastic
SOLVENT: a liquid that dissolves certain solids
LANDFILL: a place where waste is buried.
Do I really need a car?
If the answer is 'yes' then:
- I should use it as little as possible;
- Share it as much as possible;
- And always try to keep this car running, instead of buying a new one.
SHARE: to let someone else use something that belongs to you.
