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.
Water quality can be affected when farmers spray their crops with chemical pesticides and hormonal chemicals. These chemicals can seep into the ground water and eventually flow into streams and rivers. Overgrazing occurs when too many animals are kept in an area which is too small to sustain them.
