But that is not all that matters. The real world is a more complicated place, as I shall explain in a moment. And that is why a floating exchange rate regime makes sense for Canada. The case typically made for a floating rate for Canada is that it gives us the chance to run an independent monetary policy. That is true.
Over-irrigation of the soil takes out all of the embedded nutrients and makes the soil fallow. In addition, it can lead to erosion and runoff, which can make the ground less stable and less able to hold fruits, vegetables, and plants.
In fact, over the past 40 years, 30 percent of the worldâs arable land has become unproductive as a result of erosion. However, even low rates of soil erosion can severely damage agricultural land; not only does erosion reduce the water-holding capacity of a given soil, it also strips away nutrients and organic matter. In fact, soil removed by erosion contains about 3 times more nutrients and 1.5 to 5 times more organic matter than the soil that remains behind. F
