Today we learned a little bit more about mass extinction events, since they have come up in previous discussions about the evolution of sharks and prehistoric apex predators.
We got to visit a few other classes and check out their work. The highlight was watching and voting on the stop motion animation videos!
Finally, we Skyped with Jennifer Nolan, author of Sea Turtles Up Close. She shared her favorite ocean animal (dolphin), type of shark (tiger), and type of sea turtle (hawksbill). She also showed us lots of beautiful photographs of the ocean! Here are a few facts we learned from her:
- 90% of large predatory sharks have been killed
- 73 million sharks die each year. 250,000 per day!
- 80% of sharks dying are being caught for shark fin soup. The good news is that sales have dropped by 50%
- By creating marine protected areas (like underwater national parks) we can help ocean animals
- The sea turtle population is finally going up!
- Her books each took about 2 years to write
She sent me some follow up information that I wish we had been able to view in advance. If you’re interested, the links are below (I have not previewed these, but assume they are good resources).
Link to the Dr. Sylvia Earle Ted Prize acceptance speech – brilliantly made case for why we must protect our oceans.
Lastly, excellent non-profits working to protect our oceans and sea turtles as well:
