Lesson duration is: 45 minIntroduction
Lesson Five – How can we help prevent the extinction of species?
This lesson examines how each of the identified manmade issues could be addressed and shows which actions tackle issues like overfishing.
Learning activities:
Research and report on a critically endangered species and devise a plan to save it from extinction.
Identify actions that each student could take to help save marine species.

During the lesson we will use these icons to identify the learning actions.
Slide 3 - Slide
In previous lessons we have discussed what a mass extinction event is and some of the signs. We have talked about how this time the extinction event is resulting from our actions, like for instance climate change, pollution, poaching and overfishing. We have looked at how this is impacting the ocean ecosystem and our biosphere.
We have an idea of our negative impacts on the ocean, contributing to extinction of species, but how can we reverse this impact and stop this extinction event from progressing?

Slide 4 - Mind map
We discussed some of the causes of climate change as well as the impact they are having. What can we do to help stop the rate of climate change, or counter the impacts?
Ask students: “What do you think we can do, or what projects have you heard about that are tackling the impacts of climate change?” How can we help as individuals or a group?

Slide 5 - Mind map
What can we do to stop the decline of species, in particular to stop poaching?
Ask students: “What do you think we can do, or what have you heard about that is taking place to stop this issue?” Consider the laws that are in place, the poaching and the demand for various species as food.

Slide 7 - Slide
There are a number of measures in place by governments to help tackle the issue of overfishing and protect marine species.
Marine protected areas are important in order to preserve and protect biodiversity of species. In these areas species have the chance to recover.
Ask students: “What are marine protected areas and how do they protect marine species?”

Slide 8 - Video
Supporting marine protected areas is critically important.

Slide 9 - Slide
Stopping illegal fishing activities is critically important, particularly when we see the level of crime taking place in the ocean. In the video we saw that having a marine reserve is not enough. Laws prohibiting destructive activities are also required.
Discuss with students what those laws should cover.

Slide 10 - Video
Laws alone don’t protect marine reserves and the ocean. The laws need to be enforced. Monitoring for illegal activity and ensuring illegal operations are apprehended are crucial. Only by having effective surveillance and monitoring in place can we help to stop these destructive and illegal activities.
This video (3.28 min) from Sea Shepherd’s Operation Gambian Coastal Defense campaign shows the implications of illegal fishing and how patrolling can stop illegal activity and protect the ecosystem.
