"The number of weather related disasters such as severe rain or ice storms has grown over the past 100 years from almost one per year in the early 1900s to an annual average of about three since the year 2000." Ice cover on the Great Lakes is 26 per cent lower than it was 50 years ago, the report found. "And Ontario's growing season has lengthened by about 13 days from 1950 to 2018," Shulz said. There are increased algae blooms in Lake Erie and rising levels of microplastics in Lake Ontario. Dissolved oxygen levels, important for aquatic organisms such as fish, are improving in Lake Simcoe, but do not meet the environment minister's targets. The report said 60 per cent of monitored rivers and streams rate "poor" to "very poor" for biological health.
Back to top Op/Ed: Marking 50 years of wetland conservation and loss
Fifty years ago, nations gathered to create the world’s first global agreement to conserve a habitat. This had long been undervalued, and as a result was rapidly disappearing. Fifty years ago, there was a global call to action to save our wetlands. On February 2, 1971, the Convention on Wetlands of International Importance was adopted in Ramsar, Iran. Often referred to as the Ramsar Convention, its purpose was to stop the worldwide loss of wetlands. Today, 171 countries, including Canada, are parties to the convention. The Ramsar Convention has helped many wetlands. More than 2,400 wetlands around the world have been designated as Ramsar Wetlands of International Importance. Canada has 37 Ramsar sites, including two Nature Conservancy of Canada helps protect in B.C., the Columbia Wetlands and in Creston Valley. World Wetlands Day marks the signing of the Ramsar Convention and is a day to highlight the importance of wetland conservation Despite a global agreement and a special day of recognition, we have not been kind to wetlands over the last half century. Over the past 50-years, over one-third world’s remaining wetlands have been lost. They continue to disappear at a rate faster than forests, and the loss is accelerating.
