Journey to the End of Earth

Ans. Geographical lands carry fossils as imprints of history. These fossils provide important information about evolution. With the help of Modern Technology (Carbon dating) Scientist determine the age of fossil. In this way we can say geological phenomena help us to know about the history of mankind.

Ans. If the pollution keeps on increasing in the same way as it is increasing today. Future of human kind is in danger. Due to increasing pollution carbon dioxide and other poisonous gases are depleting ozone layer as a result ultra violet rays of the sun come to earth. This leads to Global warming.

Ans. Antarctica was once a part of the supercontinent. It later got separated from India and drifted south to create the present continent. The climate of this land changed from warm to extremely cold. It hence carries a lot of history with itself and can be useful for archaeological purposes too. That’s why the study of this region useful to us.

Ans. Geoff Green took high schools on the expedition because he wanted to make young minds sensitive about climatic changes that are happening around the world. He believes that these young minds are the future policy makers of the world.

Ans. The statement points out the fact that building up small habits and making little changes can bring a big positive change in the world. If every individual takes small steps, the total impact on the world will be massive. The book provides an example of phytoplankton, which are small photosynthetic plants and serve as food for several marine birds and animals. If the ozone layer depletes further, the phytoplankton might get depleted and its contribution to the ecosystem will be depleted which in turn would affect the globe on a large scale.

Ans. The land of Antarctica existed millions of years ago and is untouched by humankind. Its present state of melting and breaking apart tells that we are polluting mother earth resulting in global warming. The melting of Antarctica glaciers warns us that if humans now don’t improve their ways, the result will be very dangerous. That is why Antarctica the place to go to understand the earth’s present, past, and future.
