Journey to end of the Earth class 12 theme
The Journey to end of the Earth is an enlightening account of the author’s visit to the coolest, windiest and driest continent in the world. Tishani Doshi holds the opinion that in order to understand the Earth’s present, past, and future, one must go to Antarctica.
Journey to end of the Earth class 12 Explanation.
Early this year, I found myself aboard a Russian research. vessel-the Akademik shockalskiy -heading towards the coldest. driest, windiest continent in the world. Antarctica. my journey began 13.09 degree north of the Equator in madras. and involved crossing nine time zones. six checkpoints three bodies of water, and at least as many ecospheres
By the time I actually set foot on the Antarctic continent I hard been travelling over 100 hours in combination of a car, an aeroplane and a ship’ so my first emotion on facing Antarctica’s expansive white landscape and uninterrupted blue horizon was relief. followed up with an immediate and profound wonder, wonder at its immensity. its isolation, but mainly at how there could ever have been a time when Indian and Antarctica were part of the same landmass.
Parts of history.
six hundred and fifty million years ago, a giant amalgamated southern supercontinent -Gondwana did Indeed exist. centred roughly around the present day.
Antarctica, things were quite different then. humans hadn’t arrived on the global scene, and the climate was much warmer, hosting a huge variety of flora and fauna, for 500 million years Gondwana thrived. but around the time when the dinosaurs were wiped out and the age of the mammals got under way the landmass was forced to separate into countries, shaping the global much as we know it today.
To visit Antarctica now is to be a part of that history. to get a grasp of where we’ve come from and where we could possibly be heading. it’s to understand the significance of Cordilleran folds and pre-Cambrian granite shields. ozone and carbon evolution and extinction ,when you think about all that can pretty mind-boggling .
Imagine. Indian pushing northwards jamming against Asia to buckle its crust and form the himalayas. south American drifting off to join north America. opening up the drake passage to create a cold circumpolar current keeping Antarctica frigid. desolate. and at the bottom of the world.
For a sun-worshipping south Indian like myself, two weeks in a place where 90 percent of the Earth’s total Ice volumes are stored is a chilling prospect (not just for circulatory and metabolic function, but also for the imagination). it’s like walking into a giant ping pong ball
devoid of any human markers –no trees. billboards, buildings. you lose all earthly sense of perspective and time here. the visual scale ranges from the microscopic to the mighty. midges and mites to blue whales and icebergs as big as countries. (the largest recorded was the size of Belgium).
Days go on and on and on in surreal 24-hours austral summer light. and a ubiquitous silence. interrupted only by the occasional avalanche or calving ice sheet. consecrates the place. it’s an immersion that will force you to place yourself in the context of the earth’s geological history. and for humans. the prognosis isn’t good.
Human Civilisations have been around for a paltry 12,000 years –barely a few seconds on the geological clock. In that short amount of time. we’ve managed to create quite a ruckus. etching our dominance over nature with our villagers. towns cities megacities. the rapid increase of human populations has felt us battling with other species for limited resources ,
And the unmitigated burning of fossil fuels has now created a blanket of carbon dioxide around the world. which is slowly but surely increasing the average global temperature. Climate change is one of the most hotly contested environmental debates of our time.
Will the west Antarctica ice sheet melt entirely.? will the Gulf stream ocean current be disrupted will it be the end of the world as we know it? maybe. maybe not. Either way. Antarctica is a crucial element in this debate.–not just because it’s the only place in the world. which has over has never sustained a human population and therefore remains relatively.
Pristine. In this respect. but more importantly because it holds in its ice-cores half-million-year-old carbon records trapped in its layers of ice. if we want to study and examine the earth’s past. present and future. Antarctica is the place to go.
students on Ice, the Programme I was working with on the shokalskiy. aims to do exactly this by taking high school students to the ends of the world and providing them with Inspiring educational opportunities. which will help them foster a new understanding and respect for our planet.
It’s been in operation for six years now. headed by Canadian Geoff Green, who got tired of carting celebrities and retired, rich curiosity-seekers who could only give’ back In a limited way, with students on Ice. he offers the future generation of policy-makers a life-changing experience at an age when they’re ready to absorb, learn and most importantly. act.
The reason the programme has been so successful is because it’s impossible to go anywhere near the south pole and not be affected by it. it’s easy to be blase. about polar ice-caps melting while sitting in the comfort zone of our respective latitude and longitude. but when you can visibly see glaciers retreating and ice shelves collapsing you begin to realise that he threat of global warming is very real.
Antarctica, because of her simple ecosystem and lack of biodiversity is the perfect place to study how little changes in the environment can have big repercussions. take the microscopic phytoplankton-those grasses of the sea that nourish and sustain the entire southern Ocean’s food chain. these single-celled plants use the sun’s energy to assimilate carbon and synthesis organic compounds in that wondrous and most important of
Processes celled photosynthesis. scientists warm that a further depletion in the ozone layer. will affect the activities of phytoplankton. which in turn will affect the lives of all the marine animal and birds of the region. and the global carbon cycle. In the parable of the phytoplankton. there is a great metaphor for existence take care of the small things and the big things will fall into place
Walk on the Ocean
My Antarctica experience was full of such epiphanies but the best occurred just short of the Antarctica Circle at 65.55 degree south. the shokalskiy had managed to wedge herself into a thick white stretch of ice between the peninsula and Tadpole Island which was preventing us from going any further.
The Captain decided we were going to turn around and head back north. but before we did we were all instructed to climb down the gangplan and walk on the ocean. so there we were all 52 of us. kitted out in Gore-Tex and glares. walking on a stark whiteness that seemed to spread out forever.
Underneath our feet was a metre-thick ice pack. and underneath that 180 metres of living breathing salt water In the periphery Crabeater seals were stretching and sunning themselves on ice floes much like stray dogs will do under the shade of a banyan tree, it was nothing short of a revelation. everything does Indeed connect. .
Journey to end of the Earth class 12 summary
Geological phenomenon helps us to understand about earths, present and future the writer was working on a programme called students on ice which aimed at studying Antarctica in order to understand such geological phenomenon. it was a great educational opportunity for the high school students. it was headed by a canadian. Geoff green the main aim of the Programme was to faster new understanding and respect for planet earth among the students.
Tishani Doshi started her journey in a Russian research ship-Akademik shokalskiy she had to cross nine time zones three water bodies and three ecospheres to Antarctica 100 hours when she searched there, she wondered at its immensity and isolation.. the water tells us that 650 million years ago, there was a gaint continent’ Gondwana and things were quite different then.
The climate was much warmers. many species. of flora and fauna were present there. about 50 million years ago due to some geological disturbances the huge landmass was forced to separate into various continents.(South America, North drake passage America, Asia)
Thus Antarctica is also a part of human history. it is a place where 90% of ice of the earth is stored here we can study ozone and carbon. evolution and extinction. there are no days nights in Antarctica due to environment pollution and rise in global temperature, there are lots of changes in climatic conditions which can be studied in Antarctica (phytoplankton)
Once of the experience shared by the writer is walking on the ocean once her ship got struck into the stretch of ice. the caption decided to turn around but before the 52 passsangers were asked to walk on the frozen ocean the writer was wonderstruck at the beauty of Antarctica.
Need to Preserve the environment.

Read and Find out
Question:1 How do geological phenomena help us to know about the history of humankind?
Answer” The Geological phenomenon of separating various continents and water bodies from one compact landmass tells us about the age of existence of human race on the earth. six hundred and fifty million years ago, no human race existed on the earth because the environment was not favourable. after the time when the dinosaurs were wiped out, the Mammals started existing and after the separation of landmass, the human race started flourishing on the earth.

Question:2 what are the indications for the future of humankind?
Answer” The Future of the humankind can get in danger if the emission of carbon-dioxide and other poisonous gases go on in the same ozone manner. layer and allow the ultra-violet rays of the sun to enter the earth’s environment .this causes the rise in temperature of the earth and giving rise to the phenomenon called global warming. Increased temperature can melt the ice of the Antarctica, and cause other environmental problems, thus jeopardizing the future of human kind.

Reading with Insight
Question:1 The world’s geological history is trapped in Antarctica. how is the study of this region useful to us?
Answer” The study of this region of Antarctica gives us Insight into the world’s geological history ,it gives an idea, how the earth was like before it drifted into continents and countries. it shows can change the shape of the region. it gives the explanation how the climatic condition of the earth were not favourable for life before and how slowly rising temperature made earth a place to sustain life. all secrets are embedded in the layers of ice in the form of half million year old carbon records.
Question:2 what are Geoff Green’s reasons for Including high school students in the students on Ice expedition.?
Answer” Geoff Green took the high school students to one end of the world to provide them the opportunity to develop the respect and understanding for the earth. he wanted to make the future policy. makers to experience how difficult it would have been for the earth to sustain life by rising its temperature. he wanted them to understand that any interference in nature can cause drastic mishappenings in the future when the students see the ice shelves melting and collapsing, they can estimate the kind of environment troubles ahead in their future.
Question: 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 content of the Antarctic environment ?
Answer” This statement has great relevance in the content of the Antarctic environment. A small change in the environment can give rise to drastic developments. Antarctica has a small biodiversity. the example of small grass called phytoplankton can be studied in this content. these microscopic grasses undergo the process of photosynthesis and serve as food for number of marine. birds and animals
The Author says if there is further depletion of the ozone layer. it will affect the phytoplanktons and the carbon cycle on the global. this whole process can jeopardize the existence of all the marine birds and animals .so if we take care that processes carried over by these small grasses are carried over by these small grasses are carried out properly. the bigger animals and birds will fall into the place on their own.
Question:4 why is Antarctica the place to go to. understand the earth’s present, past and future?
Answer: Antarctica gives us an idea. how the earth would have been like millions of years ago and how it got divided into various earth masses. the melting and colliding ice masses also give us an insight into how our future is going to be. it if we continue with interference. In the working of the nature. moreover Antarctica holds into the depths of its Ice half-million year old carbon records. which are helpful in understanding the past, present and future of the earth. therefore. Antarctica is the place which reveals our past, shows our present and visualize our future.
