Question : If what I have read on a series of birthday cards about interesting things from the year YOU were born is the truth, gas prices from 1930 to 1940 increased only 1 penny, from 10 to 11 cents. In fact, in 1964 they had only gotten up to 30 cents. Then in 1980, gas was $1.19 per gallon. Somewhere in there, I suppose, was the switch.
1930-1980: increase of 89 cents;. 1980-2006: at least 181 cents (so far. I know gas prices here were 303 cents per gallon by 4:00 pm July 8)
Answer : I think the switch was in the 1950s and 1960s when americas growth took over our ability to produce as If I remember Opec started in the 1960s as a way to stabalize prices over many different member countries.
The prices are due to supply, demand, and inflation.
Milk was 10 cents a bottle in the 1950s also, now that same amount is roughly $2.00
But gas from 1980-1989 I think it was went from $1.19 down to as low as 69 cents in some areas (usually around 79 cents though around 1986-87) with gas prices going up only in the last 4years over $1.50/gal. increase (in 2003, gas was $1.39 now $2.90 in my area) but that price is due to avaliability (rememeber OPEC and the fact that one of it's members thinks we are out to kill their leader (venezuela).. China is wanting it more than they did 5 years ago... and we got greedy oil companies
I rest my case
Question : Working on my powerpoint presentation on air pollution
Answer : here's a link about air pollution...
Air Pollution Definition:
Air pollution is toxic contaminants or Volatile Organic Compounds (VOCs) which have been released into the air. All over the world, fuel, in the form of oil and coal, is burned to run factories, machinery and all forms of transportation. The burning of these fuels creates by-products such as smoke and invisible irritants which contaminate our atmosphere. Many consumer products such as hair spray, paint, cleaners, windshield washers, etc. release high levels of VOCs into the atmosphere. The cumulative effect of air pollution destroys our environment and poses health treats to humans.
Air Pollution Sources:
Cars, Consumer Products, Gas Stations, Power Stations, Agriculture & Forestry, Chemical Industry
Air Pollution Effects:
The effects of air pollution are a major threat to our health. The American Lung Association believes that sulfur-dioxide exposure (one sou..
Question : Compared to auto & truck emissions. In other words, if no homes were heated with oil, natural gas, propane, etc., would the amount of air pollution created annually be materially less? Or would there be no significant difference? (Please don't give me 'your guess'; if you have some hard facts, bring 'em on; otherwise, don't just tell me things like 'well, you KNOW most pollution comes from cars.' I'm not interested in idle speculation. Thanks!)
Answer : Because we cannot directly measure every single emission made by every home and every car, there can be no accurate information about this type of study. Any info you may find will be speculation. Until the output of every single car and home can be measured, all we can do (even scientifically) is idly speculate and share our opinions and ideas with others. In my opinion, cars emit less pollutants than homes heated with gases, especially since many homes now operate on electricity. Modern cars are designed with the environment in mind, while less work has been done to minimize emissions from homes. Since I live green for the most part, I try to minimize both by walking, riding my bike, or riding the bus when possible as well as wearing an extra sweater or blanket instead of turning up the thermostat.
