Dynamic Earth Mid-Term

Hmmm, I was not expecting another snow day. We will cancel the quiz on groundwater and caves.

Review Chapters 1,2,3,4,9,8,10,11,5, and 6

Mid-term has changed and will now be only 115 multiple choice questions. I am dropping the essays due to time constraints. Still open note.

Thanks and good luck

A Remarkable Coincidence

So Wednesday in Dynamic Earth I showed you two TED talks on oceans. The first is a very upbeat and hopeful view from Dr. Robert Ballard, the famed ocean explorer. He is a link to the talk if your interested.

Robert Ballard: The astonishing hidden world of the deep ocean

The second video is more worrisome. Coral Ecologist Dr. Jeremy Jackson has seen massive ocean ecological destruction by the hand of man during his career and tells of a dark future, with a damaged ocean.

Jeremy Jackson: How we wrecked the ocean

So I get home Wednesday night and who do I see on PBS? Jeremy Jackson. The new PBS show is called Earth: A New Wild. And looks at how humans are trying to effect a positive change on the environment by managing wilderness. Dr. Jackson and many, many others, are trying to regrow coral reefs, farm fish in the ocean instead of on land, introduce species that filter toxins from the water, and other amazing ideas.

Good show and you can watch it online. The episode I saw was “Oceans”
