Global warming and peak oil

…I believe in the secular bull market commodities thesis the strong conviction that we are still in the early-to-middle innings of the natural resource ballgame. This is an “obvious” point, but one that is important to re-emphasise when storm clouds darken the horizon…

We tend to see urban pollution as a modern problem. But did you know that urban pollution was a serious problem for Western world cities as far back as 200 years ago?

The greatest source of pollution for 19th-century cities was, believe it or not, the horse. Horses were ubiquitous back then. They drew pretty much anything that was heavy and had to move. Horse-drawn carriages, trains, wagons, supply carts…you name it.

Of course, there were no horse toilets, so these animals had to relieve themselves in the streets. This might seem like a quaint issue until one realises that the average city horse could produce up to 35 pounds of manure and 2 pints of urine a day. Yuck!
