On Picking and Choosing Facts: Shady Statistics and Propaganda
I hadn’t planned another detour from our biodiversity series this week, but after spending a day watching propaganda from both sides on the state of fish populations and fisheries, I couldn’t help but talk about sustainable fisheries. On the one side, there was a speech by this dude called Ray Hilborn, author of the book…

Underwater Forests: Seagrasses and Seaweed
How do you offset your carbon footprint? You plant trees. Right? Well, as we established in the episode on primary production, trees are actually not the major player when it comes to carbon offsetting.

But with the warming ocean waters and more extreme weather events, coral reefs are struggling. The corals bleach. But what is coral bleaching? Coral reefs are cities underwater. About a quarter…

What is a KEYSTONE Species?
Keystone species are the glue for their ecosystems and hold everything together. Without them, entire ecosystems collapse. What are keystone species? What do they do? Why do we care? All species fulfill their purposes but some species are so important that their survival is essential to the ecosystem they live in. Keystone species can determine…

What Are INVASIVE Species?
Invasive species are one of the biggest threats to ecosystems. We humans are probably the most damaging invasive species both because of the harm we cause to ecosystems and because of how carelessly we help other invasive species along. Mentioned in this episode: National Geographic: People and Invasive Species (choose your reading level) Australian Government:…
