The good news is that citizen scientists and backyard butterfly lovers from across the northeastern U.S. and southern Canada have reported through social media that monarch butterflies are arriving and laying a remarkable number of eggs. But it's too early to gauge whether the numbers will meet already low expectations.
In the mid-1990s, the eastern monarch population was more than one billion. In winter 2013, the population had dropped by more than 95 per cent to 35 million, with a modest increase to 56.5 million this past winter. Much of the monarch butterfly decline has been pinned on the virtual eradication of its critical food source milkweed.
Apart from the immediate and lethal effects on bees, neonics represent a more subtle threat to a wide range of species. The 2014 Worldwide Integrated Assessment of the Impacts of Systemic Pesticides, the most comprehensive review of the scientific literature on neonics, pointed to effects on smell and memory, reproduction, feeding behaviour, flight and ability to fight disease.
Canada's newest "national park" is a vibrant patchwork of green space meandering through dynamic downtown neighbourhoods in one of Canada's densest metropolises, along the former path of a creek buried more than 100 years. It's a welcoming space for birds and bees that's nurturing a new generation of city-builders. And it may spread to your city.
Last week, Canadian beekeepers filed a class action lawsuit in Ontario Superior Court (Windsor) against two massive chemical companies, Bayer AG and Syngenta AG, for over $400 million in losses allegedly caused by neonicotinoid pesticides to Ontario bees. This is the first Canadian class action lawsuit filed for harm to bees caused by these widely used pesticides.
Bees may be small, but they play a big role in human health and survival. Some experts say one of every three bites of food we eat depends on them. The insects pollinate everything from apples and zucchini to blueberries and almonds. If bees and other pollinators are at risk, entire terrestrial ecosystems are at risk, and so are we.
