BBC News website includes a section for special reports. One of the categories of special reports is about science and technology. In the science section I found this short slideshow about biodiversity. The slides explain what biodiversity is, the animals most threatened by environmental changes, and the implications of reduced biodiversity.

Applications for Education
The information in the BBC’s guide to biodiversity is not detailed. Therefore, it is best as a general introduction to the topic. I might consider sharing it with students and asking them to investigate the greater implications of reduced biodiversity in a particular ecosystem.
