What is the course about?

This course examines some aspects of our current climate crisis and of the 5 mass extinctions that ravaged the earth over the last 450 million years. It will give you an appreciation for the fragility of ecosystems, which can be disrupted by even the smallest change. You will also learn how scientists date rocks and how they know these extinction events took place. Scientists have not entirely explained the causes of these events and a number of possibilities will be examined for each period. This is an opportunity for you to go beyond the extinction of the dinosaurs to planetary history that featured some of the most devastating mass extinctions.

What will we cover?

- The Holocene Extinction Event: Present Day
- The Extinction of the Dinosaurs: 65 million years ago
- The Triassic-Jurassic Extinction Event: 200 million years ago

- The Ordovician-Silurian Extinction Event: 450 million years ago.
