How are coral reefs threatened?

Having explored the coral reef and its life, this last session looks at how coral reefs around the world are being threatened by human activity, including increased carbon emissions. The main activities develop an understanding of ocean acidification, the other carbon problem.

The Great Barrier Reef is currently experiencing a mass bleaching event, having suffered similar events in 2016 and 2017. This and other threats could point to the end of the coral reef as we know it.

This live lesson will review the impact of ocean acidification and discuss what we can all do to create a better future for coral reefs.

Broadcast on Thu 16 Apr 2020
  • 30 mins
  • Ages 7-11, Ages 11-14

This live lesson assumes that students and families will have completed the ocean acidification activities, Ocean acidification in a cup and Dissolving 'coral' in vinegar. There is a wealth of other resources on Encounter Edu on the impact of ocean acidification and ocean warming on coral and a selection is listed in the supporting resources.

There is also a range of background information on the threats to reefs and some of the things that can be done to help conserve them in the Coral Oceans Professional Development collection.
