Speaker Name(s): Laurence Packer, Ph.D. Description: Bees are the most important pollinators on the planet. There are 20,000 species - 800 of which are found in Canada. Not only are they responsible for 30% of the food we eat, they are excellent indicators of the quality of terrestrial environments. Everything from the tomatoes in your urban garden to trees in the forest need bees. As bee populations decline, impacts will be felt throughout the food chain and in numerous ecosystems.
