Reading with Insight

1. ‘The world’s geological history is trapped in Antarctica.’ How is the study of this region useful to us?

Antarctica stores half-million-year-old carbon records trapped in its layers of ice. By studying these ice-cores, scientists can examine the Earth’s past climate and environmental conditions. This helps us understand climate change, the effects of carbon dioxide in the atmosphere, and possible future environmental changes. Therefore, studying Antarctica allows us to understand the Earth’s past, present, and future.

2. What are Geoff Green’s reasons for including high school students in the Students on Ice expedition?

Geoff Green includes high school students in the Students on Ice expedition to provide them with inspiring educational opportunities that help them develop a new understanding and respect for the planet. He believes that young people who experience Antarctica will learn, absorb knowledge, and act responsibly to protect the environment in the future. 

3. ‘Take care of the small things and the big things will take care of themselves.’ What is the relevance of this statement in the context of the Antarctic environment?

In Antarctica, even small organisms such as phytoplankton play a very important role in the ecosystem. These microscopic plants sustain the entire Southern Ocean’s food chain and help maintain the global carbon cycle. If small elements like phytoplankton are affected, it can disturb the entire ecosystem. Therefore, protecting small environmental components helps maintain the balance of the larger ecological system.

4. Why is Antarctica the place to go to, to understand the earth’s present, past and future?

Antarctica is the only place on Earth that has never supported a permanent human population and therefore remains relatively untouched. It contains ice-cores that hold carbon records from the past many years. Studying these records helps scientists understand the Earth’s geological history, present environmental changes, and possible future climate conditions.
