Pushing the Bear is a historical novel by Diane Glancy about the Trail of Tears and the Cherokee experience in 1838 and 1839 as they traveled from their native land to reservations in the west. Told from the perspective of a number of Cherokee Indians who are on the trail, the book is interspersed with real historical documents and the voices of Christian missionaries and soldiers who were tasked with leading the Cherokee toward their new home. The book looks closely at the experiences of the Cherokee as they were exiled from their ancestral home, and the horrors they experienced on the trail.
Explanation:
I believe that the most important idea is that life without gravity is not as good as you may think. I believe this because even though you can do things you can't on earth, it has some effect on your body. Most of the excerpt is about how it affects you, and here is some proof: "If astronauts don't force themselves to exercise, their muscles become so feeble that when they return to Earth they can't even walk." As you can see, the author thinks that microgravity is bad, but there are a few sentences where he says it is a fun thing. So I believe that the main idea is that microgravity is fun, but can have terrible affects on your body.
