Throughout this podcast, we have traced the history of Antarctica from its geologic origins, its earliest discovery and the first people to set foot there, to the first research stations and into the modern world. Even though Antarctica has been impacted throughout the past 120 years from research stations, tourism, and external anthropogenic factors such as climate change and pollution, it still remains the most remote and pristine place on earth, an extreme environment so relatively few people visit it. In this final episode, I go over the greatest threats facing Antarctica today, including global warming and sea level rise, and the importance in maintaining the Antarctic Treaty and Antarctica as a world park. It is up to all of us to ensure that Antarctica remains for peaceful purposes only.
