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.
Unsustainable water use harms the environment by changing the water table and/or depleting ground water supplies. Excessive irrigation can also increase soil salinity and wash pollutants and sediment into rivers â causing damage to freshwater ecosystems and species as well as those further downstream, including coral reefs and coastal fish breeding grounds.
