What is biodiversity and why does it matter?

Understanding how to generate important evidence concerning the role of biodiversity with Dr. Callum Macgregor.

In this video we think about what is meant by the term “biodiversity”. We discuss why biodiversity is important and worth protecting. As a case study, we consider the role that biodiversity plays on farms, improving crop yields by providing the service of pollination.

Here are some questions to consider while you’re watching the video. We’d be happy to hear your views after you’ve watched the video.

• Can you think of another example of a crop that requires pollination by insects? Why are some crops able to produce a yield without insect pollinators?
• Why might plants receive better pollination by encouraging pollinators of different sizes, shapes, mouthparts and behaviours?
• “Ecosystem services” are the benefits that humans can gain from a healthy, functioning natural environment, such as pollination of crops. Can you think of another example of an ecosystem service?
