I would like to thank Joselyn Morley for her article, “Sustainability, The importance of wetlands”, in the May 12, 2021 edition of the North Grenville times. It was extremely informative. I particularly like her statement on how wetlands replenish the underground aquifers. Since so many farm fields are now tiled or are being tiled, the water that is already in the ground is being put back into either the cycle of evaporation or the runoff to rivers. This water, then, does not replenish the aquifers, making the wetlands very important.
