Beautiful and terrfiying in equal measure, this is a good new documentary on Netflix for thinking about the relationships between human actions and ocean health, as well as some good technical stories of collecting footage and data. Great visuals and explainers for symbiosis and how the corals “work”.
New from Leonardo DiCaprio and National Geographic, Before the Flood is a compelling and powerful climate change documentary. Where are we in the world right now with our understanding, challenges and potential solutions. What actions need to be taken right away?

In the current age of environmental destruction it can be difficult to keep paying attention to the news. But some stories stand out as being real alarm bells, and this very sad piece on the iconic barrier reef highlights a lot of purely human-caused issues. To add to the misery, now the reef is under further threat from destructive dredging and dumping… to make way for shipping lanes for coal mining in Australia. #EpicFail.

This is a neat animation by The Black Fish (@theblackfishorg) on Ending Overfishing, highlighting issues of overfishing, bycatch, fish-farming and the tensions between science-recommended catches and econonmy-driven catch limits. It connects directly to the Population Ecology option topic.
This video is an excerpt from George Monbiot’s recent TED Talk (posted here a while back), and really sets up the imagery of an ecosystem as it responds to change. A great clip, well suited to starting off the Ecology units.
This TED Talk from Guardian environment writer George Monbiot (@GeorgeMonbiot) makes a compelling argument for rewilding: putting back what we have taken from nature, letting the ecosystems do what they will and allowing the megafauna to re-reshape the ecosystem.
“It offers us the hope that our silent spring can be replaced by a raucous summer.”
The connections across the curriculum here are clear, most notably to 5.1 Ecosystems and HL Option G4: Conservation of Biodiversity. Well worth 15 minutes and could be the stimulus for class discussion.
I’ve featured Hank Green’s Crash Course Biology here a number of times and many of his videos have been embedded into the topic pages for the IB Biology course around this site. Prolific as he is, his ‘Crash Course Ecology’ series has just finished, so here are 12 episodes that pull together elements of the the Core and Option topics (as well as a lot more).
The full playlist is here: Crash Course Ecology. It’ll take about as long as Avatar to get through it all, and you’ll learn more about environmental change, impacts and solutions.
Episode 1: The History of Life on Earth
The rest of the episodes are linked after the jump.
These are for the Grade 10 Environmental Science students. More are on the topic page, here.
I saw this on Twitter from the QI Elves. They also posted this great clip of an eagle owl. Follow them!
Tis the season to be jolly – and to ask for new shiny gadgets to replace the still newish, slightly less shiny doodas we already have. But how often do we really think about the impacts of our disposable culture?
Watch Annie Leonard’s clip on the story of electronics and take principled actions this holiday season.
