“Journey to the End of the Earth” by contemporary Indian poet, novelist, and travel writer Tishani Doshi (born 1975) is an evocative, ecologically urgent travel memoir recounting her voyage to Antarctica aboard the Russian research vessel “Akademik Shokalskiy”. Participating in Canadian educator Geoff Green’s pioneering “Students on Ice” programme, Doshi travels across nine time zones, six checkpoints, three bodies of water, and multiple ecospheres to reach the coldest, driest, and windiest continent on Earth. Antarctica, holding 90% of the world’s ice volumes and devoid of human trees, billboards, or cities, offers an unaltered geological window into Earth’s distant past, present, and imperiled future. The narrative charts the history of Gondwana—the giant amalgamated southern supercontinent that existed 650 million years ago before continental drift—and issues a stark warning on modern climate change, retreating ice shelves, and the fragile role of microscopic phytoplankton, emphasizing that small environmental disruptions in simple ecosystems trigger catastrophic global collapse.
❄️ What happens when high school students walk across the bottom of the world to witness the end of time?
Imagine standing on a continent with no trees, no billboards, and 90% of Earth’s ice, where 24-hour austral summer light illuminates calving icebergs as large as countries. In “Journey to the End of the Earth,” Tishani Doshi takes readers on an unforgettable expedition to Antarctica, revealing that understanding our planetary future requires looking straight into the ice of our ancient past.
Why This Chapter Matters
Prescribed as Chapter 3 of NCERT Class 12 English (Vistas), this essay is an essential environmental text addressing anthropogenic climate change, global warming, carbon emissions, and geological continental drift. It teaches students to appreciate the delicate interconnectedness of planetary ecosystems. It frequently features in board exams for questions on the Gondwana supercontinent, the rationale behind Geoff Green’s “Students on Ice” initiative, and the ecological importance of phytoplankton.

1. The Voyage: Across Nine Time Zones to the End of the Earth
The expedition begins aboard the Russian research ship Akademik Shokalskiy. Departing from Madras, author Tishani Doshi crosses nine time zones, six checkpoints, three large bodies of water, and at least as many ecospheres. After over 100 hours of combined travel by car, aeroplane, and ship, she experiences profound physical and emotional relief as she lays eyes on Antarctica’s expansive white landscape and uninterrupted blue horizon.
The planetary archive: the research vessel navigating 90% of Earth’s ice and half-million-year carbon records.
2. Gondwana: 650 Million Years of Geological History
Six hundred and fifty million years ago, a giant amalgamated southern supercontinent called Gondwana existed around present-day Antarctica. At that time, humans had not arrived on the global scene; the climate was warm and tropical, supporting a vast variety of flora and fauna. For 500 million years Gondwana thrived until the landmass was forced to break into separate continents, shaping the globe as we know it today, opening the Drake Passage to create a cold circumpolar current that keeps Antarctica frigid and isolated.
3. The Pristine Canvas: 90% of Earth’s Ice
Visiting Antarctica is like stepping outside human time. It contains 90% of the Earth’s total ice volumes and is completely devoid of human markers—no trees, no billboards, no buildings. Visual scale ranges from the microscopic (midges and mites) to the colossal (blue whales and icebergs as large as countries like Belgium). The 24-hour austral summer sun bathes the silence, punctuated only by the booming crack of an avalanche or calving ice sheet.
4. Geoff Green & “Students on Ice”
Doshi traveled as part of the “Students on Ice” programme founded by Canadian educator Geoff Green. Green had grown tired of ferrying wealthy celebrities and retired tourists who only absorbed Antarctica passively without giving anything back. Instead, he chose to take high school teenagers:
Future Policy-Makers:
High school students are at the ideal age to absorb, learn, and most importantly, act. Watching glaciers retreat and ice shelves collapse with their own eyes makes climate change real, instilling an enduring reverence for planetary ecosystems in future leaders.
Students on Ice: future leaders walking on the frozen ocean, witnessing climate vulnerability firsthand.
5. The Phytoplankton Metaphor: Small Things Matter
Antarctica’s simple ecosystem provides a vital scientific laboratory through phytoplankton—single-celled microscopic marine grasses that nourish the entire Southern Ocean food chain through photosynthesis. Depletion of the ozone layer threatens the activities of these tiny organisms, which would endanger all marine birds, whales, and the global carbon cycle.
The Core Parable:
“Take care of the small things and the big things will fall into place.” If humans protect the microscopic foundations of the ecosystem, global planetary health will be sustained.
6. Walking on the Ocean: The Ultimate Epiphany
The voyage culminates when the ship wedges into thick sea ice at 65.55 degrees south. The captain instructs all 52 participants to disembark. Walking on a meter-thick ice floe with 180 meters of living salt water underneath, Doshi watches crab-eater seals basking on ice floes like stray dogs under a banyan tree. The experience leaves an indelible impression: everything on our planet is interconnected, and human survival depends on respecting natural balance.

Conceptual Solved Examples & Case Studies
Example 1
‘The world’s geological history is trapped in Antarctica.’ How is the study of this region useful to us? (Reading with Insight)
Step-by-Step Solution:
Antarctica is the supreme geological and climatic archive of our planet:
Continental Evolution: It reveals the origins of the ancient supercontinent Gondwana, illustrating how landmasses broke apart, formed the Drake Passage, and pushed India northward into Asia to create the towering Himalayas.
Carbon & Climate Archive: Trapped within its pristine ice cores are half-million-year-old carbon records that allow scientists to study Earth’s past atmosphere, temperature shifts, and climate cycles.
Future Projections: By observing melting glaciers and collapsing ice shelves in Antarctica, scientists can accurately forecast sea-level rise and the catastrophic trajectory of global warming.
Example 2
What are Geoff Green’s reasons for including high school students in the Students on Ice expedition? (Reading with Insight)
Step-by-Step Solution:
Canadian educator Geoff Green included high school students because:
Future Policy-Makers: High school students represent the upcoming generation of leaders, scientists, and decision-makers who will shape global environmental policy.
Receptivity to Change: Unlike wealthy celebrities and retired tourists who only absorbed Antarctica as a curious vacation spot without giving back, teenagers are at an impressionable age where they are ready to absorb, learn, and take decisive action.
Firsthand Climate Reality: Witnessing melting ice shelves firsthand transforms abstract textbook warnings into an urgent, visceral commitment to planetary survival.
Example 3
Why is Antarctica the place to go to, to understand the earth’s present, past and future? (Reading with Insight)
Step-by-Step Solution:
Antarctica provides a holistic three-dimensional window into our planet:
Past: Preserves the history of the Gondwana supercontinent, continental drift, and half-million-year-old atmospheric carbon records trapped in deep ice cores.
Present: Because it has no human settlements, trees, or commercial buildings, it offers an unpolluted, pristine baseline to measure contemporary climate health.
Future: It gives a terrifying preview of what will happen if carbon emissions continue unabated—melting ice sheets will drown coastal cities worldwide, while ozone depletion threatening phytoplankton will collapse the global marine food web.
