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.
