How long will it last?
Most of us know that natural resources are finite. Due to those pesky laws of physics, there’s only so much stuff on this little planet of ours. New Scientist poses (and then answers) an interesting question: How much do we have left? And how long will it take to deplete these resources at present rates?
Not surprisingly, we don’t have a lot of years left with many of our favorite natural resources given current consumption rates. The chart presents both the rate of consumption for the U.S. (we’re #1! in a bad way) and for the world, based on an assumption that global consumption goes up to half that of the U.S. (with developing nations striving to match our standard of living, it’s not a bad assumption).
The takeaway here is not that we’re going to all of a sudden run out of Indium and stop making LCD monitors. Instead, this should remind us all that we need to drastically change the way we interact with natural resources over the next century if we want to maintain anything close to our current standard of living.
At the risk of politicizing an otherwise apolitical post, I’ll also add this: When you hear politicians tell you that we can’t do anything to change the way we produce energy or to increase the efficiency of everyday processes because it costs too much, ask yourself this: what’s the cost of doing nothing?
