My Footprint is Way Too Big

If everyone consumed as much as Americans, how many planets would we need?
Three
. America's rate of consumption is so high that if the whole world consumed like America we would need three planets to sustain us.

What percentage of the world's forests have we lost in the last 300 years?
50%. Experts also believe we've lost 1/2 of our wetlands and grasslands.


What percentage of the world's population lives on less than $2 a day?
50%. A 2001 survey by the world bank showed that 1.1 BILLION people lived on less than $1 a day.


How much of the world's habitable space is owned by religions?
7-8%. I hope they're sharing.


In a 1997 survey, the value of services provided by nature was 30 TRILLION dollars. Is that higher or lower than the GDP of the US?
Higher. The GDP of the US in 2005 was $12.5 trillion. Wow, nature is 2 1/2 times more valuable than a year of productivity. Nature's services include water filtration, water supply, air filtration and pollination.


How much rainforest is the Amazon losing each year?
16,000 square miles or an area about equal to the land mass of Switzerland.


What do scientists predict will be the world's population in 2050?
8 to 10 billion. BILLION. Some experts believe that 500 million is a sustainable population level. You know what a billion is?

By weight, which animal is the most abundant on earth?
Krill...these are crustaceans. That's another reason why our oceans are important.


Rainforests contain what percentage of the earth's plants and animals?
50% And the rainforest covers only 3% of the earth's surface. Hmm, I guess the rainforest is very important in the scheme of things.


What will happen if CO2 levels continue to rise?
According to some estimates, in 2050 CO2 levels may be as high as when the earth was 300 feet higher. If sea levels rise along with CO2 concentration, the effect would be devastating. Ten percent of the earth's population lives in coastal areas within 32 feet of sea level.


This was a test on ecology. I only got three right.

That's three more than me Lin. Horrifying. As is the post and comment below. The connection is so patently obvious, how could you think any other way. But then people were convinced the earth was flat at one point...

Lin, I don't think I would know any of these.

I get an education from every one of your posts!
