Wetlands in Canada are diminishing due to the expansion of agriculture and subdivisions.

Wetlands in Canada are indeed diminishing due to factors such as agriculture and urban development. According to a report by the Canadian Wildlife Federation, Canada has lost over 70% of its wetlands due to human activities. Agriculture often involves drainage of wetlands to make way for crops, while urban development leads to the conversion of wetlands into subdivisions and other infrastructure. The loss of wetlands has significant ecological impacts, including loss of habitat for wildlife, decreased water quality, and increased risk of flooding.
