Exploring Patagonia's Frozen Giant
In Exploring Patagonia's Frozen Giant, host Simon Reeve and his guide reach the breathtaking Grey Glacier in Patagonia, a massive four-mile-wide glacier that's part of the South Patagonian ice field. Simon explains how climate change has caused the glacier to retreat about 328 feet (100 meters) every year, showing the urgent need to protect these icy giants. As they trek onto the surface, Simon is amazed by its creaks, groans, accompanied by howling winds, making it feel alive. He reflects on how this wild place reminds us of our connection to nature and the importance of preserving it. This video is excerpted from BBC’s Wilderness With Simon Reeve, an epic adventure into the heart of Earth’s last great wild areas, where nature is at its most beautiful and fragile.
Lesson Express
Q: How does the retreat of the Grey Glacier highlight the impact of climate change on our planet?
A: The retreat of the Grey Glacier, which has been moving back by 328 feet (100 meters) each year, shows how climate change is causing glaciers to shrink. This is a clear sign that the planet's temperature is rising, affecting the environment and ecosystems that depend on these glaciers.
Q: Why do you think Simon describes the glacier as "almost alive"? What does this tell us about the glacier’s importance in the ecosystem?
A: Simon describes the glacier as "almost alive" because of the creaks and groans he hears while on top, suggesting that glaciers are dynamic and constantly changing. This helps us understand that glaciers are not just frozen ice but are active parts of the environment, playing a crucial role in water cycles and supporting life downstream.
Q: If glaciers are retreating due to climate change, what do you think could happen to the rivers and ecosystems that depend on them?
A: If glaciers continue to retreat, rivers that rely on the meltwater could dry up, affecting the ecosystems that depend on those water sources. This could lead to a loss of biodiversity, as many plants and animals depend on the fresh water from glaciers to survive.
