Global Population & Resource Scarcity

Are you aware that global population has doubled in the past 40 years, going from 3.3 billion to just under 7 billion today? Think about that for a minute. Forty years is an insignificant number in the global scale of time, and yet, in the past 40 years alone we have doubled the number of people living on this planet. And while much of this growth has occurred in rapidly developing countries such as China and India, it should still concern you. Why? Because, according to the Worldwatch Institute, in the very near future food demand from China and India alone will likely exceed the current global agricultural production capacity, driving global food prices higher as countries compete for ever-dwindling agricultural resources.

In fact, you are likely seeing evidence of this trend in your grocery prices right now. What’s more, water tables on every continent are declining as we pump out water at greater rates than rainwater can replenish it, (and human waste continues to foul what water we have left). Right now, more than 400 million people suffer from water scarcity, and the Population Media Center predicts that number will hit the 2 billion mark soon – 25% of the entire planet’s population. Two commodities that we all take for granted, food and water, will within your lifetime very likely become as precious as gold. And finally, exponential growth in population is mirrored by increases in demand for oil – that precious and incredibly efficient source of energy that our society relies upon.

It may surprise you to learn that the world’s supply of oil is diminishing, and according to most scholars on the subject, we have already ‘peaked’ in oil production at a time when demand is at an all-time high and expected to grow exponentially. Given that most of society relies upon oil for manufacturing, food production, supply and distribution, transportation, construction, etc., etc., what do you think our world will look like when oil prices skyrocket due to shortages. Think about it…
