(Video "The Death of Bees Explained: Parasites, Poisons, and Humans from Kurzgesagt and The Nova Project)
Although we don’t entirely know why, bees are disappearing. While scientists have several theories as to why this might be happening, the overarching conclusion is that widespread impact will occur as the bee population dwindles. Some theories about the disappearance of bees include parasites called varroa mites that weaken the bee by sucking fluid from their bodies. It’s hard to kill these mites without also harming the bees, making this a particularly hard problem to navigate. Bees also need plenty of food and water to survive; but with human population growth their access to clean water and plants may be limited.
There are several things we can do to help bees stick around. Supporting local beekeepers by buying their honey products is one way to make sure that they have the resources to help their hives survive. Another helpful strategy is planting blooming plants. Not only does this provide bees with the pollen they need, but it’s also great motivation to have a beautiful garden. However, when planting anything it is important to avoid insecticide dusts as well as any neonicotonoid pesticides. Both of these can get carried back to the hive.
In 1988, there were five million hives. Today, there are 2.5 million. While we aren’t entirely sure why so many colonies are collapsing, we can be sure that the loss of bees would change the world.
To see what other effects the loss of bees would have as well as what may be causing the decline, watch the video from Kurzgesagt and The Nova Project.
