Here’s a quick look by the numbers at where we’re in trouble on key environmental issues. I’ve borrowed a bit from the style of the Harper’s Index, and a bit from those before/after ads for weight loss products. Except that it’s not weight that we’re losing:

Atmospheric Carbon Dioxide levels:

Estimated pre-industrial CO2 levels: 280 parts per million

1958 CO2 levels: 317 parts per million

1990 CO2 levels: 356 parts per million

2009 CO2 levels: 391 parts per million

U.S. air travel passenger miles:

1960: 33.9 billion passenger miles

1990: 358.9 billion passenger miles

2006: 590.6 billion passenger miles

U.S. car travel passenger miles:

1960: 1.145 trillion passenger miles

1990: 3.561 trillion passenger miles

2006: 4.994 trillion passenger miles

(Yes, that’s right: As of the last full year posted by the U.S. Bureau of Transportation statistics, if you count up every mile traveled by every passenger or driver of every car in the U.S., we travelled almost 5 trillion miles on roads in 2006. That means we drove 570 million miles an hour.)

1960: 17.1 billion passenger miles

1990: 6.0 billion passenger miles

2006: 5.4 billion passenger miles

U.S. coal use, 2007: 1.129 trillion tons

China coal use, 1980: 678.5 billion tons

China coal use, 2007: 2.893 trillion tons

Worldwide coal use, 1980: 4,127 trillion tons

Worldwide coal use, 2007: 7,193 trillion tons

U.S. oil imports:

Barrels imported, 1960: 590 Million Barrels

Percentage of oil that was imported, 1960: 16.7%

Barrels imported, 2007: 4.395 Billion Barrels

Percentage of oil that was imported, 2007: 58.2%

Number of U.S. presidents that have vowed to cut oil imports since 1960: 11

What, me worry?

Percentage of Americans who think global warming concerns are exaggerated, 1998: 31%

Same polling question, 2009: 41%

Don’t worry, be thrifty

Percentage of Americans who prefer environmental protection even if it harms the economy, 1984: 60%

Same question, asked amidst the recession of 2009: 42%

Catching the last one:

Chesapeake Bay oyster landings, 1880: 10,000,000 bushels

Chesapeake Bay oyster landings, 2006: 45,000 bushels

Are you on the list?

Average annual endangered species listings during the Reagan administration: 32

Want not…:

Average amount of food thrown away by each American each day: 1.3 pounds

Dead Sea level:
