Economic growth needs many supply side resources such as food
& water for the population, fossil fuels, metal ores etc. There is a
growing concern that we would run out of resources impacting economic growth.
But at the tipping point, when many predicted worse, things seem to change for
better. Read more on this.
The biggest debate on this subject was at the rate we were
burning oil, we would run out of them in few decades. Economy won’t advance if
we don’t have sufficient energy to produce goods or services or transport them
around. So the oil prices went up above $100/barrel increasing inflation in the
importing countries and many thought oil prices would never soften. But shale
technology changed the industry landscape. Last year, US produced more oil than
Saudi. And oil is traded at the half-price sustain-ably for many months now.
Forget inflation, welcome deflation! Those who predicted high price of oil are
licking their wounds.
Similarly in the agriculture domain, when there was no additional
arable land was available, use of fertilizers took up the productivity. Now advances
in bio-technology seem to be the next wave to improve agricultural output.
World’s population has more than doubled in the last 50 years while the available
land did not double up but yet this population is fed better comparatively.
Many are concerned that water would become the reason for the
next world war. But we are finding ways to recycle water, preserve rain water, or
cut water use in agriculture through drip irrigation etc. Those who are
predicting water shortfall might be overestimating the demand or ignoring the
improvements which would come in time.
Before coal runs out, wind and solar would have become
significant sources of energy production.
Whenever we approach the limits of available resources, a new
vista opens up taking these limits higher.
Though the depleting resources have some irreversible impacts
on ecology, focus of this blog post is on its impact on economic growth.
In the debate between Environmentalists (who find limits to
growth) versus Economists (who are helped by innovation to overcome the limits),
the optimists have had the last laugh always. Next time when you get into
similar debate, do remember there is no reason to get pessimistic completely and hoping
for better would not prove you wrong.
