Threats to the sustainability of bee pollination for year 11 and 12 Earth and Environmental Science

there’s been increasing concern about two different things one is that the honey bees so the bees we’re providing in a box are finding it harder and harder to live in our agricultural landscapes and when i say that i’m talking about the whole world this is not just a problem for australia this is a problem that the whole world is thinking about so when you see stuff on the news about oh bees are in decline often what they really mean is that one particular kind of bee the honey bee is in decline and that’s not a b that’s native to australia that’s a b that evolved in europe and north africa but that’s still a real issue because it’s important to be able to provide the bees in the box when you need them as a farmer but the other thing is um we’ve got well in australia we probably have um three to six thousand species of bee we don’t even know how many because there aren’t enough people that study bees to answer that question so we’ve got all of these wild species globally there’s probably 20 000 or more species of bee and then there’s other insects that are contributing to pollination and they’re not necessarily declining for the same reasons that honey bees are declining but they they are threatened by loss of habitats and the presence of insecticides on farms just in the same way that many um much of nature is so when you read about b decline that’s often really what it’s talking about is the risk that we’re losing honey bees and we might be losing wild bees and that can be causing problems for the production of food but there’s a lot more nuance to that story i want to tell you that we’re not at it’s not quite the crisis that’s painted in the in the um in the media sometimes but there are some real issues really important issues that um that where we as researchers are trying to help to understand better and provide better ways both for producing food but also creating an environment that’s better for humans to live in you
